Claron Polyseal Double Acting Piston Seal CS2 CS4

Get a quote

Design:

Claron composite seals styles CS2 and CS 4 are designed for use in light duty hydraulic or pneumatic piston applications. Style CS2 covers the range of imperial sizes, and CS4 the metric sizes.

Materials:

Claron composite seals style CS2 and CS4 as standard comprise of a Virgin PTFE outer sleeve and are energised by a

75° shore hardness Nitrile rubber O-Ring. A full range of materials are available to suit a variety of applications. See tables in Appendix 2.

Operating conditions:

Maximum Working Pressure for “Standard” seal applications using specified tolerances. Temp Range:               -40°C to +120°C           (Dependent upon energiser material. See Appendix 2) Max. Pressure:                  350 Bar

Max. Linear Speed: 15m/s

These range parameters are maximum conditional values

Optimum service conditions are affected by temperature, speed pressure, surface finish and extrusion gaps.. Refer to Appendix 1 section for further information.

‘F’ shown in the size tables is based upon Virgin P.T.F.E., temperatures up to 80oC and 350 Bar pressure in designs where PTFE guide tape is utilised. For other pressures, refer to the graph shown below.

To use this graph, refer to the tables on for the max. value of ‘F’ at 350 Bar then apply the relevant curve for the various pressures.

The maximum extrusion gap ‘F/2’ should be calculated allowing for all movements due to tolerances, side-loads and cylinder expansion.

How to order:

When ordering, quote the size reference shown on the dimensions table.

If an energiser material other than the standard nitrile type is required, consult Claron for the part number to be used.

For the seal to function correctly it is important that care is taken during fitting. For details refer to Appendix 3.
