Carbon-filled PTFE (Polytetrafluoroethylene) bearing bushes are high-performance components used in various industrial applications. The addition of carbon to PTFE enhances its mechanical properties, making it suitable for demanding environments. These bearing bushes are known for their low friction, self-lubricating nature, and durability.

1. Key Characteristics of Carbon Filled PTFE Bearing Bushes

  • Low Friction: The carbon filling reduces the coefficient of friction, allowing for smooth and efficient operation in sliding applications.
  • Self-Lubricating: Carbon-filled PTFE does not require additional lubrication, which reduces maintenance and downtime.
  • Chemical Resistance: PTFE is inherently resistant to chemicals, and the addition of carbon improves its durability against various corrosive environments.
  • Wear Resistance: The carbon particles help to improve the wear resistance of the bearing, extending the service life of the component.

2. Common Applications

  • Automotive Industry: Used in car engines and other moving parts like piston rings, valve guides, and bushings due to their ability to withstand high temperatures and friction.
  • Aerospace: In aircraft and spacecraft components that require low friction and high performance, such as landing gear bearings and actuators.
  • Industrial Machinery: Carbon-filled PTFE bearing bushes are used in pumps, valves, conveyor systems, and food processing equipment, where low maintenance and high wear resistance are crucial.
  • Marine Applications: These bearings are also used in marine engines and shaft bearings due to their resistance to seawater and ability to operate under harsh conditions.

3. Benefits of Carbon Filled PTFE Bearing Bushes

  • Cost-Efficiency: Reduces the need for external lubrication, saving on maintenance costs.
  • Extended Service Life: The wear resistance ensures longer-lasting components in critical applications.
  • Versatility: Suitable for both high-load and low-speed operations across various industries.

Carbon-filled PTFE bearing bushes offer a reliable, low-maintenance solution for applications where durability, chemical resistance, and high performance are essential.
