SF-1D oilless lubricating bearing (hydraulic type)


Product parameters
  Substrate properties
  SF-1D oilless lubricated bearings (hydraulic-specific) materials have been developed to meet the needs of high-load, fluid-lubricated hydraulics. Special additions have been added to PTFE wear-resistant materials for SF-1D oilless lubricated bearings (hydraulic-specific) The lipophilic fiber makes the material more resistant to cavitation and fluid corrosion than the general PTFE bearing; at the same time, under the condition of fluid lubrication, the friction factor of this material is extremely low and the wear resistance is better. Higher PV values can be achieved.
  Material organization
  1. The mixture of PTFE and fiber is 0.01~0.03mm, which can form a good transfer film to protect the grinding shaft and provide self-lubricating performance of the bearing.
  2. The copper powder layer is 0.20~0.35mm, which has good bearing capacity and wear resistance. Good thermal conductivity can transfer the heat generated during the operation of the bearing. The composite material can penetrate into the gap of the copper powder ball to improve the bonding strength.
  3. Low carbon steel provides good load bearing performance and heat transfer.
  4. Copper/tin plating layer is 0.002mm, which makes it have better corrosion resistance.

  typical application

  SF-1D oilless lubricating bearing (hydraulic-specific type) is specially developed for high-load fluid lubrication conditions, mainly used in automotive suspension systems, shock absorbers, power steering pumps, steering systems, gearboxes, etc., general industrial applications. Medium hydraulic motor, gear pump, plunger pump, vane pump, cylinder guide sleeve and logistics machinery. SF-1D oilless lubricated bearings (hydraulic-specific) are primarily used to provide excellent wear resistance and stable dynamic/static friction factors under fluid lubrication conditions.
