Single acting U-Section NBR piston / rod seal with rubberised fabric reinforcement.

- Design -

CLARON STYLE GP is designed with a symmetrical profile for Piston or Rod 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.

- Operating Conditions -

Maximum Pressure

Max Speed
Temp. Range
-30°C to 100°C
250 Bar
400 Bar
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 -

Style GP is designed for use on a split piston and may be used with Claron Seal Retainer Style PSR. 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.
