    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 .
