Double Acting Piston Seal
Designed for use on one piece pistons, the five part assembly consists of an endless precision rubber mouldedsealing element supported at each end with angle split support rings. The support rings are designed to accommodate
split Polyacetal anti-extrusion bearing rings.The design allows the anti extrusion bearing rings to react positively to increasing pressures. The final assemblyprovides a robust sealing unit designed to operate at higher pressures.The seal is also suitable for existing two piece pistons of the same housing dimensions.
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.
Fit seal onto the piston in the following sequence.1- Rubber Sealing Element
2- Support Rings
3- Polyacetal bearing rings.
It is important that care be taken in fitting the seal within its housing.Refer to Appendix 3 for check list.

Designed for use on split pistons, the seal is a precision moulded Nitrile rubber element with bonded rubberised fabricreinforcements. The seal is designed with initial radial interference such that when fitted low pressure sealing is effected.
Rubberised fabric has the advantage of retaining the sealing media within its surface, thus reducing friction and wear.Style DP has proven to be effective over a wide range of applications.
Optimum service conditions are affected by temperature,speed, pressure, surface finish and extrusion gaps.
Refer to Appendix 1 for further information.Ma x i m um D iam e t r a l C l e ar a n c e F
For surface finish and recommended lead in chamfers refer to the illustration below. For housing dimensions and machiningtolerances 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.

Designed for use on split pistons, the seal is a precision moulded rubber element with rubberised fabric reinforcements.Style DPE is fitted with Polyacetal anti-extrusion rings on the O.D. to allow larger machining clearances between the
piston head and cylinder bore, and to permit higher working pressures. The seal is designed with sufficient radial sectionalinterference that on complete assembly low pressure sealing is effected. The supporting rubberised fabric has the capabilityof retaining the sealing media thus assisting in reducing friction and wear. Style DPE has proven to be effective over a widerange of applications.

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.

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 completelyon one side, in the temperature range of -30C to 100CThe 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 thepressure capability of the seal.

Designed for use on split pistons, the seal is a precision moulded rubber element with rubberised fabric reinforcements.Style DPW is fitted with clip on anti-extrusion bearing rings on the O.D. to allow larger machining clearances between the
piston head and cylinder bore, and to permit higher working pressures. The Polyacetal bearing rings also support thepiston head under side load conditions thus preventing metal to metal contact. The bearing rings are an integral part of theseal therefore react directly to operating pressures thus closing the extrision gap. The seal is designed with sufficientradial sectional interference that on complete assembly low pressure sealing is effected. The supporting rubberised fabrichas the capability of retaining the sealing media thus assisting in reducing friction and wear.
Style DPW has proven to be effective over a wide range of applications.

DPW/LDouble Acting Piston Seal Metric
Imperial
Designed for use on split pistons, the seal is a precision moulded rubber element with rubberised fabric reinforcements asstyle DP but with additional full width Polyacetal anti-extrusion bearing rings at each end to allow larger machining
clearances between the piston head and cylinder bore, and to permit higher working pressures. The Polyacetal bearingrings also support the piston head under side load conditions thus preventing metal to metal contact. The seal is designedwith sufficient radial sectional interference that on complete assembly low pressure sealing is effected. The supportingrubberised fabric has the capability of retaining the sealing media thus assisting in reducing friction and wear.Style DPW/L has proven to be effective over a wide range of applications and is a popular alternative for existing housing
designs.
For surface finish and recommended lead in chamfers refer to the illustration below. For housing dimensions and machiningtolerances 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.
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 temperaturerange of -30C to 100C. The use of a suitably selectedClaron bearing ring will effectively reduce the clearance

Diametrical Clearance Fshown in the graph is calcu-lated as the maximum permissible extrusion gap, allowing formovement due to side load, for various pressures andtemperatures upto 80C. This product is intended for use with
eitherSTYLE PBR orSTYLE BGF Bearing Rings whicheffectively reduce the Radial clearance to a value nearer to
F/2 thus increasing the pressure capability.The maximum seal extrusion gap should be calculatedallowing for all tolerances, movement and cylinder expansion.For pressures > 400 bar, the seal extrusion gap should bereduced by utilising smaller tolerances. e.g H8 for Cylinderbore, 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
