Design:

Claron Style CPI is designed for use as a single acting rod seal. The seal is a precision moulded Nitrile rubber sealing element with a fabric reinforced base and an acetal back up ring to resist extrusion. The acetal back up ring allows larger clearances and higher pressures. Designed with initial radial interference to effect low pressure sealing, at higher pressures the seal is progressively energised thus increasing the sealing force. Rubberised fabric has the advantage of retaining fluid within its surface so reducing both friction and wear. Style CP is produced with radial grooves incorporated into the top of the seal on the pressure side. This innovative design ensures a rapid energisation of the seal without excessive end float and resultant wear.

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:

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.
