Design:

Claron composite seals Style CSPG are designed as high pressure, Low Friction Double-Acting Piston Seals for use in heavy duty hydraulic cylinders as found in mobile equipment to American designs.

Materials:

laron Style CSPG consists of a glass filled high performance P.T.F.E. sealing eliment, energised by a precision moulded rectangular section NBR rubber.

Operating Range:

Temp -40°C to 120°C Pressure upto 800 bar Velocity upto 15m/s

These range parameters are maximum conditional values. Optimum service conditions are affected by temperature, speed, pressure, surface finish and extrusion gaps.

Refer to Appendix 1 for further information.

Operating Conditions:

Diametrical Clearance F shown in the graph is calcu- lated as the maximum permissible extrusion gap, allowing for movement due to side load, for various pressures and temperatures upto 80°C. This product is intended for use with either STYLE PBR or STYLE BGF Bearing Rings which effectively reduce the Radial clearance to a value nearer to F/2 thus increasing the pressure capability.

The maximum seal extrusion gap should be calculated allowing for all tolerances, movement and cylinder expansion. For pressures > 400 bar, the seal extrusion gap should be reduced by utilising smaller tolerances. e.g H8 for Cylinder bore, f8 for piston diameter either side 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.
