Wear-Resistant Low-Friction Piston

XIAYI Wear-Resistant Low-Friction Piston is a precision damping component developed for shock absorber systems requiring stable friction performance and extended service life. The piston plays an important role in controlling hydraulic movement, maintaining damping force consistency and reducing vibration during continuous compression and rebound cycles.

Compared with conventional sintered pistons that experience rapid friction deterioration after long-term operation, XIAYI optimizes the piston structure with reinforced low-friction PTFE material, high-density powder metallurgy substrate and precision surface processing technology. The improved material system maintains stable friction characteristics under repeated movement, high-temperature oil immersion and complex road conditions.

Friction Performance Control

Friction stability directly affects damping accuracy, driving comfort and shock absorber durability. During long-term vehicle operation, unstable friction behavior may cause damping fluctuation, abnormal noise and reduced suspension performance.

XIAYI focuses on maintaining consistent friction characteristics throughout the product service cycle by optimizing PTFE material formulation and processing parameters.

Modified PTFE Material Structure

Different from ordinary single-component PTFE materials, XIAYI uses reinforced modified PTFE formulas to improve wear resistance and aging resistance.

The optimized material structure helps maintain smooth piston movement and reduces friction coefficient changes caused by continuous wear.

Stable Low Friction Output

The piston maintains a friction coefficient of ≤0.2 under tested working conditions.

Stable friction performance helps reduce damping fluctuation and supports consistent shock absorber response during long-term operation.

Long Cycle Wear Resistance

Shock absorber pistons continuously experience high-frequency reciprocating movement. Wear resistance determines whether the damping system can maintain stable performance over time.

100,000 Cycle Friction Retention

XIAYI products maintain 98% friction retention after 100,000-cycle testing.

The wear-resistant PTFE surface reduces performance decline caused by repeated contact and movement, helping extend shock absorber service intervals.

Million Cycle Durability Verification

The piston supports fatigue simulation testing up to 5 million cycles to evaluate long-term operational reliability.

The verification process ensures stable performance under high-frequency vibration environments.

Precision Manufacturing Process

The performance of damping pistons depends not only on material selection but also on manufacturing accuracy and process consistency.

High Density Powder Metallurgy Base

XIAYI uses FC-0208 powder metallurgy substrate with controlled density ≥6.8g/cm³.

The stable substrate provides mechanical support for the PTFE band and ensures consistent piston operation.

Precision Surface Grinding

Advanced grinding technology controls dimensional accuracy within ±0.01mm.

Accurate surface processing improves piston-cylinder matching and supports reliable sealing performance.

Performance Test Data

XIAYI performs laboratory verification and durability simulation tests to evaluate friction stability, bonding reliability and environmental adaptability.

Overseas Application Case

European Shock Absorber Manufacturer Project

Case Background: A European shock absorber assembly manufacturer experienced durability issues with conventional pistons. After long-distance vehicle operation, the products showed surface wear, friction attenuation and increased chassis noise, resulting in higher customer complaints.

Cooperation & Application Effect: In early 2024, the customer introduced XIAYI Wear-Resistant Low-Friction Piston into mass production. After 18 months of road testing and market verification, the pistons maintained more than 97% friction stability with no abnormal wear or damping attenuation. Shock absorber service life increased by more than 40%, and customer after-sales failure rate decreased from 8.2% to below 0.08%.
