Commercial Ring Slides
And Track SystemThis catalogue is a supplement to the Ring Slides and Track
System product and is intended for customers who require a
lower precision, lower cost solution. It should be read in
conjunction with Hepco's Precision Ring Slides and Track
System Catalogue as illustrated.
Customers should please take note of the following:
1 Commercial Ring Slides and Tracks are hardened but not
ground. They are suitable for less demanding applications
which do not require the degree of smoothness, quietness and integrity of shape
associated with the Precision System. Running quality may vary between straight
slides and curved segments in Track Systems due to the wider tolerances to which
these components are made. The above characteristics are not detrimental in
applications for which the Commercial System is intended.
2 The bearing assemblies, carriages and lubricators
which form part of the Commercial System are not
detailed in this supplement. These components
are identical* to those for the Precision
System, and customers should refer to that
catalogue for details. * Fixed centre
carriages however, have different hole centres
for the bearings and therefore have different
part numbers (see ordering example
page 7). Customers wishing to make
their own carriages should refer to
Hepco for revised dimensions.
3 Load capacity and life
expectancy for Commercial
Rings is the same as for the
precision versions, and may
be taken from the Precision
System catalogue.

Assembled Commercial Ring System
The Hepco Ring system may be used in either complete ring form or as segments. The carriage may be used to run on the ring
track (see below) or constructed in order to embrace the complete ring where the bearing assemblies may be placed internally
and / or externally. In all cases either the ring or the carriage may be the moving component. The specially developed Hepco
'R' series bearing assemblies have sufficient adjustment to enable complete removal of the ring slide from the carriage in most
cases.
Notes:1. Two lengths of stud are availab le for each size beari ng assembly. Choose according to your required carriage thickness.
2. Of fset holes in carr iage for eccentric bear ing assemblies, necessitate adjustment rotation in direction shown.
3. Standard p inions are available from most manufacturers to suit gear drive option slide rings.
4. Exact theoretical values have been given for 'Q ' ' R' and 'S'. Positional accuracy of dimension 'S' wi ll determine the axis of the ring. Positional accuracy for
dimensions 'Q ' and ' R' are not normally cri tical. Holes for bear ing assemblies should be reamed to tolerance as per dimension ' R' on page 17 of the Precision
System catalogue.
5. Lubricators (see Precision Systems Catalogue) greatly enhance system life. It is recommended to specify at least 10% of carr iages (minimum 1) in a system
with lubricators.
6. Fixed centre carr iages supplied wi th Commercial Ring or Track systems wi ll not necessarily be suitable for use on precision systems. Customers should not
attempt to make these themselves without reference to Hepco.

Assembled Commercial Ring System
When using rings as shown below it is recommended that two concentric bearing assemblies should be placed 120apart in
order to provide a datum reference. The other bearing assemblies used should be the eccentric type. All eccentrics may be
used where positional adjustment of the ring is required. One or more lubricators may be fitted at convenient positions to take
advantage of the increased load/ life afforded by lubrication.

Commercial Ring Slides and Segments
Hepco CR series slide rings are manufactured from high quality steel, zone hardened on the V edges with datum register faces
provided both internally and externally for ease of location. Gear drive options are available with teeth machined into either
the internal or external register face. The number of teeth on the standard external option is divisible by 12 in order to provide
maximum choice of pinion size for exact ratio requirements. Customers may also choose the tapped hole option 'N' which
enables the slide ring to be bolted from below.

Commercial Ring Slides and Segments
Hepco CR series ring segments are cut from complete 360o
slide rings and held in stock in nominal 90o
and 180o
sections.
Any length segment can to be cut to customer's special order and additional holes drilled as required. Although suitable for
most applications, some out of roundness and flatness may be experienced with slide rings and segments in their free
unmounted condition. This may be substantially overcome by installing against a register and bolting to a flat surface.
Notes:1. Standard r ing segments wi ll be slightly less than 90
oand 180
obecause of the cutting allowance. Full 90
oand 180
osegments can be supplied to customer's
special order.
Special comm ercial rings up to 1.8m in outside diam eter are now availa ble. Please see pa ge 10 .

Commercial Track Systems
Hepco track systems provide a unique method of achieving an almost limitless variation of controlled routing. Any number of
carriages can be accommodated, either the fixed centre economy type which is suitable for unidirectional bends of the same
radius or the bogie type which enables 'S' bends of varying radii to be negotiated and provides a larger platform for mounting
purposes. Various drive possibilities exist some of which are illustrated in the applications section on pages 6-9 of the Precision
System Catalogue. Please note that commercial track systems are manufactured to commercial tolerances as complete systemsand that spare parts ordered subsequently cannot be guaranteed to fit. Customers requiring identical spare part replacement
and optimum smoothness of transition across joints should consider the Hepco precision system.
Installation Procedure:
Hepco commercial track systems are supplied in separate sections ready for installation marked with an individual sequence
number. Track system slides should be assembled and clamped in position as a complete circuit prior to dri lling through all the
holes and bolting down the straight sides. Final adjustment of the joins should be carried out using the keyway alignment facility
if provided, ensuring both jacking screws are subsequently locked and all curved segment fixing screws are tightened. A final
stoning of the 'V' faces is necessary to blend the joints.

Track system curvedsegment (see note 2)
Track system straight slide
See ordering details
Bogie carriage
Commercial Track Systems
Notes:1. W ith the fixed centre carriage an amount of play is experienced as each pair of opposing bearing assemblies traverses the join between straight and curve.
This is not normally detrimental in most applications.
2. Due to the cutting procedure, Hepco 90O and 180O curved segments are supplied slightly shorter than their theoretical length (see page 9). This is not
detrimental to the smoothness of travel across the join, provided installation has been carried out according to procedure (see page 6).
3. Bearing assembly hole positions in the commercial f ixed centre carriages differ f rom those of the Precision System. Lubricators are optional but should be
specified for at least 10 % of carriages on a system. Due to these differences, part numbers vary slightly from those of the Precision System (see ordering
example below)
4. The optional jacking screw alignment facility greatly assists installation and setting. This may be specified by quoting the adjustment key reference for the
straight slides (page 8) and the alignment facilitiy reference for the curved slides (page 9).
Ordering details:Simply list the curved segment and straight slide part numbers in sequential order in clockwise direction (see arrows in
illustrations), starting at any point according to preference. Viewing plan elevation as per illustrations and travelling
clockwise round the circuit curved segments should be designated suffix 'C' for clockwise bend and suffix 'A' for
anticlockwise bend. The final item should indicate the quantity and part number of the carriages required.

Hepco commercial track system curved segments are modified from stock 90oand 180
oslide ring segments. The segment ends
are ground square to a specified dimension relative to the true shape of the segment and an optional clearance keyway and
tapped hole facility may be incorporated in each end to provide an easy method of alignment when assembled together with
the optional mating key of the track system straight slide. An additional fixing hole is provided at each end of the segment to
give extra support at the join position. All track system curved segments are marked with a sequence number to aid assembly.

Special Commercial Rings, Segments & Track Systems
10
Commercial rings are now available up to 1.8m outside diameter. Although customers are recommended to choose standard
catalogue components for reasons of economy and off the shelf availability, Hepco's specials department welcomes enquiries
for non-standard commercial rings and track systems. Our team of highly skilled technicians working with the most up to date
equipment is able to cope with complex special requirements producing a cost effective solution with surprisingly short delivery
times.
The V profile can often be incorporated with the customer's own design, resulting in a single multipurpose component.
Hepco's highly sophisticated heat treatment techniques can provide a choice between zone hardening and through
hardening depending on size and shape.
Rings of non-standard section and diameter can be produced, often from material held in stock. Stainless steel rings and track
systems can be manufactured depending upon size and degree of hardness required. Alternatively, various plating processes
may provide adequate corrosion resistance. Hepco application engineers are always on hand to provide advice and
recommendations. Please consult us for your special requirements, preferably at an early stage of the design process.
A small selection of special ring components is shown below.
Rings can be manufactured with single V profile only either internal, or external.
Gear cutting can be carried out as shown with full face available for gear cutting opposite the V.
Hepco P3 grade flat slides can be rolled into special ring segments
of various lengths and diameters (see separate Hepco GV3
catalogue for slide section details).
Ring disc. V may be internal, external or both.
Rings can be made with the Hepco Heavy Duty Slide profile. These are compatible with a number of
bearing assemblies with a load capacity up to 2.0 tonnes per bearing. Please see Hepco Heavy Duty Slide System catalogue.
