Deisng:

CLARON STYLE GP is designed with a symmetrical profile for Rod or Piston applications. The seal is a precision moulded Nitrile rubber with a fabric reinforced base to resist extrusion. Designed with initial radial interference to effect low-pressure sealing, the seal is progressively energised at higher pressures thereby increasing the sealing force. Rubberised fabric has the advantage of retaining the sealing media within it’s surface, thus reducing friction and wear. Style GP is designed to provide effective low pressure sealing through distortion of the lips rather than “squeeze”. This gives an improved response to pressure variations and reduces low pressure stiction to ensure a smoother return stroke.

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. For Piston applications refer to section B.

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.
