SF-1B oilless lubricating bearing (bronze base)


Product parameters
  Substrate properties
  It has the same material properties as the SF-1B oilless lubricated bearing (bronze base), and because the bearing matrix replaces the carbon steel substrate with bronze, it is more resistant to corrosion than the SF-1B oilless lubricating bearing (bronze base). High thermal conductivity, and the copper substrate also has good magnetic resistance. It is necessary to consider that SF-1B oilless lubricated bearings (bronze-based) products cannot be used with aluminum base holes because of the risk of electrochemical corrosion when used in all fields or at high humidity.
  Material organization
  1. PTFE/fiber mixture 0.01-0.03mm, a wear-resistant material, which can form a transfer film during operation to protect the grinding shaft and provide self-lubricating performance of the bearing.
  2. Copper powder layer, 0.20-0.35mm, improves the bonding strength of PTFE mixture and copper plate layer, and has good bearing capacity and wear resistance. The higher thermal conductivity allows for rapid transfer of heat generated during operation.
  3. Copper substrate, improve bearing capacity and heat transfer, and have better corrosion resistance.

  typical application

  The SF-1B oilless lubricated bearing (bronze-based) material is suitable for long-running applications where maintenance is not required under dry friction and safety is required. Due to its corrosion resistance and anti-magnetic properties, and its good thermal conductivity, these bearings are suitable for use in high temperature environments and can be used in automotive door hinges, trunk hinges, engine hinges, wipers, hand brakes, trailer connectors, outdoor lifts. , marine winches, marine chains, dam transmission parts bushings, drying furnaces, textile machinery, metallurgical machinery, cylinder ear bushings and office equipment, etc. need to prevent corrosion.
