Sure-Grip® Bushings

FeaturesSure-Grip® “Quick Detachable” bushings are easy to install and remove. They are split through flange and taper to provide a true clamp on the shaft that is the equivalent of a shrink fit. All sizes except JA and QT have a setscrew over the key to help

STANDARD MOUNTING REVERSE MOUNTING

1. Cap screws from outside through drilled holes in the mating part and into threaded holes in the bushing flange located on the inside of the assembly. Or the complete as sembly reversed on the shaft and;

2. Cap screws from inside through drilled holes in the mating part and into threaded holes in the bushing flange located on the outside of the assembly.

3. Cap screws from inside through drilled holes in the bushing flange located on the inside of the as sembly and into threaded holes in the mating part.

4. Cap screws from outside through drilled holes in the bushing flange located on the outside of the as sembly and into threaded holes in the mating part.

Cap screws used to secure bushings to sheave and to remove bushing from sheave.

Keyseat 180° from split.

Precise taper (3/4 in. per ft. on diameter) provides proper wedging action.

Saw cut through flange and taper (and sometimes cut down into keyway also) to provide a true clamp fit.

6-hole drilling (most sizes) makes installation and removal quick and easy.

maintain the bushing’s position on the shaft until the cap screws are securely tightened. Sure-Grip bushings have a very gradual taper (3/4-inch taper per ft. on the diameter) which is about half the inclined angle of many other bushings. The result is the Sure-Grip securely clamps the shaft, with twice the force of those competitive bushings, to provide extreme holding power.

Versatile Sure-Grip bushings permit the mounting of the same mating part on shafts of different diameters, and the mounting of different sheaves on the same shaft using the same bushing. Their interchangeability extends through sheaves, pulleys, timing pulleys, sprockets, flexible and rigid couplings, made-to-order items by Wood’s, and to product lines of several other mechanical power transmission manufacturers.

Sure-Grip bushings are manufactured with the drilled and tapped holes located at a precise distance from the keyseat; thus, a wide mating part having a bushing in each end can be mounted on a common shaft with the two keyways in line. This feature not only facilitates installation but also permits both bushings to carry an equal share of the load.

SURE-GRIP® BUSHINGS

Bore and Key Seat DimensionsSure-Grip Bushings are available from stock with all the bores and keyseats listed below. In some cases, as the bore increases in diameter, a shallow keyseat is provided—due to insufficient metal thickness. When this happens, Wood’s furnishes the correct rectangular key to suit at no charge. This does not affect the bushing’s ability to transmit the load. The rectangular key, or flat key as some call it, fits into the standard keyway in the shaft.

Sure-Grip® Bushings

Installation InstructionsThe Sure-Grip tapered, QD-type interchangeable bushing offers flexible and easy installation while providing exceptional holding power. To ensure that the bushing performs as specified, it must be installed properly.

Before beginning, make sure the correct size and quantity of parts are available for the installation. The bushing has been manufactured to accept a setscrew over the key and its use is optional. It is packaged with the hardware on sizes SH to M and loosely installed in the bushing on sizes N to S.

To Install:IMPORTANT: DO NOT USE LUBRICANTS IN THIS INSTALLATION!1. Inspect the tapered bore of the sheave and the tapered surface of

the bushing. Any paint, dirt, oil, or grease MUST be removed.2. Select the type of mounting (See Fig. 1 or 2) that best suits your

application.

3. STANDARD MOUNTING: Install shaft key. (Note: If key was furnished with bushing, you must use that key.) Install bushing on clean shaft, flange end first. If bushing will not freely slide on the shaft, insert a screwdriver or similar object into the flange sawcut to act as a wedge to open the bushing’s bore. Caution: Excessive wedging will split the bushing. If using the setscrew, tighten it just enough to prevent the bushing from sliding on the shaft. Caution: Do not over-tighten setscrew! Slide sheave into position on bushing aligning the drilled holes in the sheave with the tapped holes in the bushing flange. (Note: Install M thru S bushings so that the two tapped holes in the sheave are located as far away as possible from the bushing’s sawcut.) Loosely thread the cap screws with lockwashers into the assembly. DO NOT USE LUBRICANT ON THE CAP SCREWS!

4. REVERSE MOUNTING: With large end of the taper out, slide sheave onto shaft as far as possible. Install shaft key. (See shaft key note in #3 above.) Install bushing onto shaft so tapered end will mate with sheave. (See wedging note in #3 above.) If using the setscrew, tighten it enough to prevent the bushing from sliding on the shaft. Caution: Do not over- tighten setscrew! Pull the sheave up on the bushing, aligning the drilled holes in the bushing flange with the tapped holes in the sheave. Loosely thread the cap screws with lockwashers into the assembly. DO NOT USE LUBRICANT ON THE CAP SCREWS!

5. Using a torque wrench, tighten all cap screws evenly and progressively in rotation to the torque value in Table. There must be a gap between the bushing flange and sheave hub when installation is complete. DO NOT OVER-TORQUE! DO NOT ATTEMPT TO CLOSE GAP BETWEEN BUSHING FLANGE AND SHEAVE HUB!

To Remove:1. Relieve drive tension by shortening the center distance between driver and

driven sheaves.2. Lift off belts.3. Loosen and remove cap screws. If the bushings have keyway setscrews,

loosen them.4. As shown below, insert cap screws (three in JA through J bushings, two in

QT and M thru W bushings and four in S bushing) in tapped removal holes and progressively tighten each one until mating part is loose on bushing. (Exception: If mating part is installed with cap screw heads next to motor, with insufficient room to insert screws in tapped holes, loosen cap screws and use wedge between bushing flange and mating part.)

5. Remove mating part from bushing and, if necessary, bushing from shaft.

CAUTION: The tightening force on the screws is multiplied many times by the wedging action of the tapered surface. If extreme tightening force is applied, or if a lubricant is used, bursting pressures will be created in the hub of the mating part.

Metric Sure-Grip® Bushings

FeaturesSure-Grip® “Quick Detachable” bushings are easy to install and remove. They are split through flange and taper to provide a true clamp on the shaft that is the equivalent of a shrink fit. All sizes except JA and QT have a setscrew over the key to help

maintain the bushing’s position on the shaft until the cap screws are securely tightened. Sure-Grip bushings have a very gradual taper (3/4-inch taper per ft. on the diameter) which is about half the inclined angle of many other bushings. The result is the Sure-Grip securely clamps the shaft, with twice the force of those competitive bushings, to provide extreme holding power.

Versatile Sure-Grip bushings permit the mounting of the same mating part on shafts of different diameters, and the mounting of different sheaves on the same shaft using the same bushing. Their interchangeability extends through sheaves, pulleys, timing pulleys, sprockets, flexible and rigid couplings, made-to-order items by Wood’s, and to product lines of several other mechanical power transmission manufacturers.

Sure-Grip bushings are manufactured with the drilled and tapped holes located at a precise distance from the keyseat; thus, a wide mating part having a bushing in each end can be mounted on a common shaft with the two keyways in line. This feature not only facilitates installation but also permits both bushings to carry an equal share of the load.

Metric Sure-Grip® Bushings

Installation InstructionsThe Sure-Grip tapered, QD-type interchangeable bushing offers flexible and easy installation while providing exceptional holding power. To ensure that the bushing performs as specified, it must be installed properly.

Before beginning, make sure the correct size and quantity of parts are available for the installation. The bushing has been manufactured to accept a setscrew over the key and its use is optional. It is packaged with the hardware on sizes QT to J.

To Install:IMPORTANT: DO NOT USE LUBRICANTS IN THIS INSTALLATION!1. Inspect the tapered bore of the sheave and the tapered surface of

the bushing. Any paint, dirt, oil, or grease MUST be removed.2. Select the type of mounting (See Fig. 1 or 2) that best suits your

application.

3. STANDARD MOUNTING: Install shaft key. (Note: If key was furnished with bushing, you must use that key.) Install bushing on clean shaft, flange end first. If bushing will not freely slide on the shaft, insert a screwdriver or similar object into the flange sawcut to act as a wedge to open the bushing’s bore. Caution: Excessive wedging will split the bushing. If using the setscrew, tighten it just enough to prevent the bushing from sliding on the shaft. Caution: Do not over-tighten setscrew! Slide sheave into position on bushing aligning the drilled holes in the sheave with the tapped holes in the bushing flange. Loosely thread the cap screws with lockwashers into the assembly. DO NOT USE LUBRICANT ON THE CAP SCREWS!

4. REVERSE MOUNTING: With large end of the taper out, slide sheave onto shaft as far as possible. Install shaft key. (See shaft key note in #3 above.) Install bushing onto shaft so tapered end will mate with sheave. (See wedging note in #3 above.) If using the setscrew, tighten it enough to prevent the bushing from sliding on the shaft. Caution: Do not over- tighten setscrew! Pull the sheave up on the bushing, aligning the drilled holes in the bushing flange with the tapped holes in the sheave. Loosely thread the cap screws with lockwashers into the assembly. DO NOT USE LUBRICANT ON THE CAP SCREWS!

5. Using a torque wrench, tighten all cap screws evenly and progressively in rotation to the torque value in Table. There must be a gap between the bushing flange and sheave hub when installation is complete. DO NOT OVER-TORQUE! DO NOT ATTEMPT TO CLOSE GAP BETWEEN BUSHING FLANGE AND SHEAVE HUB!

To Remove:1. Relieve drive tension by shortening the center distance between driver and

driven sheaves.2. Lift off belts.3. Loosen and remove cap screws. If the bushings have keyway setscrews,

loosen them.4. As shown below, insert cap screws (three in JA through J bushings, two in

QT bushings) in tapped removal holes and progressively tighten each one until mating part is loose on bushing. (Exception: If mating part is installed with cap screw heads next to motor, with insufficient room to insert screws in tapped holes, loosen cap screws and use wedge between bushing flange and mating part.)

5. Remove mating part from bushing and, if necessary, bushing from shaft.

CAUTION: The tightening force on the screws is multiplied many times by the wedging action of the tapered surface. If extreme tightening force is applied, or if a lubricant is used, bursting pressures will be created in the hub of the mating part.

Sure-Grip® Narrow (Ultra-V) Sheave

Features

Wood’s Ultra-V sheaves are constructed of fine grain, high tensile cast iron, and have been carefully engineered to assure maximum performance over a long life span. Behind each sheave is one of the most extensive engineering design and testing programs in the industry.

With the advent of higher V-belt ratings, Wood’s engineers instituted additional careful test programs to ensure that each Wood’s sheave would be capable of safely and dependably delivering the increased performance which was required by the new ratings. Wood’s engineers, using a special strain gage test stand, subject sheaves to tension and compression stresses far in excess of those encountered in actual operation.

In another standard test procedure, Wood’s sheaves are operated at extremely high speeds. Sheaves are selected from warehouse stocks and tested until they are burst by centrifugal force. Such destructive testing allows Wood’s engineers to study the effects of construction and balance on sheave performance. The goal is to assure safe operation at normal speeds. Other continuing programs check product quality in the laboratory and on the manufacturing line.

For applications with special requirements, Wood’s sheaves are also available on a made-to-order basis in either cast or ductile iron, and in Sure-Grip or bored-to-suit construction.

Wood’s stock narrow sheaves are available with the convenient Sure-Grip QD type bushing. Easy to install and remove, these split, tapered bushings grip the shaft with the equivalent of a shrink fit. This tight holding power eliminates freezing and fretting

corrosion between the shaft and the bore and assures quick removal and interchangeability when necessary.

Stock sheaves are designed to carry the loads of all belts shown in this catalog and other similarly rated V-Belts. For special higher rated V-Belts, consult Wood’s Engi neering Department for recommendations.

We cast or stamp the maximum safe operating speed, in rpm, on all sheaves we manufacture.
