Plastic Bushing | Engineering Plastic Bushing for Wear Protection

Plastic bushings are used outside of mechanical parts to protect metal counterparts or abrasive parts from wear due to long-term rotation.

Multiple engineering plastic materials are available according to operating temperature, chemical environment, wear resistance, mechanical strength, and application requirements.

Protects Metal Counterparts Reduces Rotational Wear Wear-Resistant Materials Multiple Material Options

Advantages of Plastic Bushings

Plastic bushings are used outside of mechanical parts to protect metal counterparts or abrasive parts from wear due to long-term rotation.

  • Protection for Metal Counterparts
  • (Helps reduce direct contact and wear between metal parts).
  • Reduced Rotational Wear
  • (Suitable for long-term rotating or sliding applications).
  • Multiple Engineering Plastic Materials
  • (Material selection can be based on temperature and operating conditions).
  • Application Flexibility
  • (Suitable for different mechanical parts and industrial equipment).

Typical Material Selection Scenarios

High-Temperature and High-Strength Applications

PEEK, PPS, and TPI Self-lubricating provide options for elevated temperatures, mechanical strength, dimensional stability, and demanding industrial environments.

Chemical and Electrical Applications

PVDF, PP, and PTFE provide options for chemical resistance, electrical properties, hydrolysis resistance, non-stick performance, and lubrication.

General Wear and Mechanical Applications

NYLON and POM provide options for wear resistance, high hardness, low friction, rigidity, and dimensional stability.

※ Actual material selection should be evaluated according to operating temperature, mechanical load, rotational speed, friction conditions, chemical environment, dimensional requirements, and product structure.

Plastic Bushing Material Selection Guide | Temperature Ranges and Applications

Material Selection: Multiple engineering plastic materials are available according to different operating environments and temperature requirements.

PEEK | Long-term use temperature 240℃

PEEK is a semi-crystalline engineering plastic, suitable for applications that used in high temperature, chemical solvent process. PEEK material is tough, rigid, creep-resistant, light-resistant, and multi-ray resistant.
