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.
| Maximum Pressure | ||
| Max Speed | Temp. Range | Temp. Range |
| m/s | -30°C to 80°C | -30°C to 100°C |
| 1.0 | 280 Bar | 250 Bar |
| 0.5 | 450 Bar | 400 Bar |
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.
