Internal Piston Function

Maintaining Pressure Separation

A PTFE Piston Ring works between the piston and cylinder wall to help separate different pressure areas inside the shock absorber. Proper sealing performance ensures controlled oil movement during compression and rebound cycles.

Supporting Piston Movement

During repeated piston movement, the piston ring helps maintain smooth operation and reduces instability caused by excessive clearance between components.

Material Performance

Low Friction Properties

PTFE materials provide excellent self-lubricating characteristics, reducing friction during continuous sliding movement and helping improve the working efficiency of shock absorber systems.

Temperature Resistance

Shock absorbers may operate under different temperature conditions. PTFE materials maintain stable performance under temperature changes, supporting reliable vehicle operation.

Sealing Requirements

Oil Flow Control

The piston ring plays an important role in controlling hydraulic oil movement inside the shock absorber. Stable sealing helps maintain consistent damping force during vehicle operation.

Clearance Management

Proper clearance between the piston ring and cylinder surface is essential for balancing sealing performance and smooth movement. XIAYI controls dimensional accuracy to meet customer specifications.
