Single Acting Piston Seals

Standard Material

Seal Ring: Filled PTFE Elastomer: Nitrile rubber NBR Polyurethane PU * Other material combinations can be customized according to working conditions.

Product Introduction

JDA seal is used to seal pistons,plungers and accumulators,consists of an elastic lip seal ring and a PTFE slide ring with abrasion resistance feature.

Characteristics

High pressure stability under pressure & harsh conditions High wear resistance Low friction,no stick-slip tendency

Application Suggestion

Slide ring of this seal forms a mating face with the piston to achieve a sealing effect. The profiled elastomer has a sealing function, providing elastic force to the slide ring. JDA seal is suitable for the sealing of hydraulic cylinder pistons and is generally used in conjunction with guide ring.

Operating Condition

Single acting piston seals

Single acting piston seals contain pressure on one side of a piston without leakage. This allows maximum effort to be applied to moving the piston along the bore of a cylinder. Single acting piston seals only contain pressure on one side of the piston. The seal is required to retain pressure from that direction, which then moves the piston along the cylinder in a ‘single action’ – hence the name.

It is worth noting that the piston in single-acting cylinders may have oil on the pressure side only, with the opposite sidefilled with air. Therefore, piston seals should leave a minimum of oil film when passing along the cylinder bore. The transportation of oil would otherwise result in a leakage. The air side of single acting cylinders may also push air out and draw air in as the piston reciprocates. This air may carry moisture and contaminants into the cylinder, which can also lead to seal damage.
