ENGINEERING DATA: SERIES PB CLAMPS

SEALS AND FLUIDSUrethane and Nitrile seals are standard on all Series PB

Clamps. Piston seals are long life Nitrile and rod seals are lip type. Both are compatible with standard paraffin-based lubrication oils used for pneumatic cylinders. For compatibility with other fluids, consult PHD.

TEMPERATURE LIMITSSeals and clamp mechanism are designed for use in

temperatures from –�0° to 180°F [–30° to 8�°C]. For higher temperatures, consult PHD.

LIFE EXPECTANCYAll units with urethane and Nitrile seals have been designed for

millions of cycles with minimal seal wear and minimal backlash.

LUBRICATIONSeals and clamp mechanism are prelubricated at the factory for

service under normal operating conditions.

MATERIALClamp body is made of hard anodized aluminum. Rod and

operating mechanism are manufactured from hardened steel.

SPECIAL CLAMPSClamps for special applications, severe duty, or constructed of

special materials are available. Consult PHD.

ADJUSTABLE ARM POSITIONSeries PB Clamps allow the rod or arm clamping position

to be rotated clockwise or counterclockwise up to 90 degrees from the parallel location. This eliminates the need for special angled arms.

To reposition the clamping location, first remove air pressure, then loosen the three locking screws on the bottom of the rear plug. Engage the three spanner holes in the plug and turn, moving the rod to a new clamping position. Maintain the rod position by holding the rear plug and retighten the three locking screws to 1�5 in-lb [14.1 Nm] (PBx4, PBx5) or 50 in-lb [5.7 Nm] (PBx�, PBx3). The rear plug should not extend past the rear face of the body.

LOCKING SCREWS

SPANNER HOLES

ADJUSTMENT RANGE

APPLICATION CONCERNS

Hold the arm (not theclamp body) whenloosening or tighteningthe arm mounting screw.

LOAD

Do not attach heavy armsor weights to the clampwithout reducing rotationspeed.

Do not machine the armwhile it is still attached tothe clamp. The forcesgenerated may damagethe internal components.

Eliminate impact to thearm as it may damage theinternal components.

Do not stop clamp armduring its rotary stroke (dim.S�). The arm may only bestopped during its clampstroke (dim. S3).

AB1 ANTI-BACKLASH ARM

Anti-backlash arm and guide are made from hardened steel and can be used to minimize the amount of arm backlash when clamping. Maximum clearance between arm and guide is .0�8 in [0.71 mm] resulting in a maximum total radial play of 0.8° max.

TA STEEL SPINDLE

Steel spindles are plated steel with two hex nuts included.

SR SPEED REDUCER FITTINGS

SR fittings provide a speed reducing orifice in a male to female hex connector. They reduce speeds so larger rotational mass moments of inertia can be accommodated. SR fittings are brass, so they are easily visible.

Use care that pipe sealant or Teflon tape does not plug the orifices.

When Series PB Clamps are used with standard ASA or ASB Arms, AB1 Antibacklash, WC1 Weld Covers and TA Spindles, speed controls are NOT required.

If longer arms or heavier loads are attached, clamps need to be protected from the higher Rotational Moment of Inertia (Jm) by slowing down their speed. PHD recommends nonadjustable speed reducing fittings for these applications. They contain orifices sized to reduce speed and allow higher moments of inertia.

The graphs below show maximum loads allowed based on the distance from the piston rod centerline to the load centerline.

Graphs 1 and � show maximum attached load with ASB Arm. Graphs 3 and 4 show maximum attached load with ASB Arm, Antibacklash (AB1), and Weld Cover (WC1) options.

These graphs assume the following:The clamp is mounted vertically.Loads are attached to ASB Arms or identical customer-supplied aluminum arms.The arms are only .5 inch longer than the distance to the centerline of the load.For customer-supplied arms or attached loads that differ from the parameters listed above, use the equations supplied on the next page to calculate their Rotational Moment of Inertial (Jm).




Jm = Rotational Mass Moment of Inertia (in-lb-sec�)g = Gravitational Constant (386.4in/sec)weight = lbR = distance from CL of rod to CL of weight (inches)

Arm Calculation for Jm

Attached load Jm Calculation

Example: PBL5L-1- WC1 with special arm and attached loadArm material is aluminum, density is .1 lb per cubic inchW is 1.0 inchH is 1.0 inchF is 4.0 inchB is 1.0 inchR is 3.0 inchAttached load is .3 lb

Arm Jm Weight of F is 4 x 1 x 1 x .1 = .4 lbWeight of B is 1 x 1 x 1 x .1 = .1 lb

Attached Load Jm Attached load is .3 lb R = 3.0

Weld Cover Jm from Chart A = .00127 in-lb-sec2

From Chart A, Allowable Jm is .030 in-lb-sec�, SR40 fitting is not required.If the Jm had been larger than .030 in-lb-sec�, then SR40 fitting would be required.
