Claron Polyseal Single Acting Rod Seal CPU/F

Design:

The Claron style CPU…/F is a symmetrical profiled lip seal manufactured in a high performance grade of Polyurethane and is suitable for both rod and piston sealing. The sealing lips are machine trimmed to ensure dimensional consistency and good low pressure sealing. Polyurethane exhibits outstanding abrasion and extrusion resistance.

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 for further information.

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:

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.
