CS8

Double acting NBR energised 98° Shore A Polyurethane piston seal for one piece pistons to ISO/European housing standards.

- Design -


Designed for use on one piece pistons, Claron Style CS8 consists of a precision moulded high performance 98°Shore Polyurethane outer sleeve, pre loaded and pressure energised by a square section NBR 80°Shore rubber element. The compact design allows smaller width pistons to be used, and offers excellent wear resistance on a wide range of surface finishes.

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





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 the illustration below. For housing dimensions and machining tolerances refer to the table of recommended sizes and Tolerance Tables for value of tolerence symbols



- Fitting -


For the seal to function correctly, it is important that care be taken in fitting the seal within its housing. For details refer to Seal Installation.
