Design:

Designed for use on one piece pistons, the three part assembly consists of an endless precision rubber moulded sealing element supported at each end with split polyester support rings. The seal is also suitable for existing two piece pistons of the same housing dimensions.

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.
