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.
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.
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.
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.
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 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.
