Design:

CLARON STYLE PW…/L is a precision moulded Nitrile rubber with a fabric reinforced base. Produced with initial radial interference to effect low-pressure sealing, the seal is progressively energised at higher pressures thereby increasing the sealing force. Rubberised fabric has the advantage of retaining the sealing media within it’s surface, thus reducing friction and wear. The full width polyacetal bearing ring resists extrusion of the seal to allow greater clearances and higher pressures, and provides bearing support for the piston preventing misalignment and metal to metal contact between piston and bore.

These range perameters are Maximum simultaneous conditions. Optimum service conditions are affected by temperature, speed, pressure, surface finish and extrusion gaps.

Refer to Appendix 1 section for further information.

Maximum Diametral Clearance F

Note: Clearance gap F is the maximum permissable. i.e. gap completely on one side, in the temperature range of -30°C to 100°C

The use of a suitably selected Claron bearing ring will effectively reduce the clearance gap F max. to a value closer to F/2 thus increasing the pressure capability of the seal.

Housing:

For surface finish and recommended lead in chamfers refer to the illustration below. For housing dimensions and machining tolerances refer to the catalogue page of selected seal. Refer to Appendix 4 for value of tolerance symbols.

Fitting:

Style PW/L is designed to be fitted onto a split piston and may be used with Claron seal retainer Style PSR.For the seal to function correctly, it is important that care be taken in fitting the seal within its housing. For a detailed checklist, refer to Appendix 3.
