Specifications

Key Advantages

Self-lubricating Performance: Manufactured via powder metallurgy with uniformly distributed internal pores for oil storage. Automatically forms an oil film during operation, significantly reducing the friction coefficient and maintenance frequency.

High Wear & Seizure Resistance: Tin bronze material combines strength and toughness. The dense sintered structure resists wear and seizure even under high-speed and heavy-load conditions.

Precise Flange Positioning: The one-piece flange design enables automatic positioning during installation, preventing axial movement and improving transmission stability and assembly efficiency.

Customizable Adaptation: Supports customization of parameters such as inner diameter, outer diameter, length, and flange size to meet the precision matching requirements of different equipment.


Material & Process

Material: Tin bronze (grades like CuSn6/CuSn8 available), oil content ≥18%, density 6.2–6.8 g/cm³

Process: Powder compaction → high-temperature sintering → sizing → oil impregnation, ensuring uniform structure and dimensional accuracy up to IT7–IT8

Surface Treatment: Natural finish/phosphating/tin plating available for enhanced rust prevention and wear resistance

      Application Scenarios

      Automotive Industry: Steering systems, brake pedals, seat adjustment mechanisms

      Construction Machinery: Excavator and loader pin bushings, hydraulic pump and valve group bushings

      Precision Equipment: Textile machinery, printing equipment, office equipment, transmission components

      General Machinery: Motor, reducer, conveyor equipment bearing housings
