SF-1T oilless lubricating bearing (special for gear pump)


Product parameters
  Substrate properties
  The SF-1T oilless lubricated bearing (special for gear pump) is a newly developed self-lubricating bearing for high speed and high load. The porous copper powder sintered layer and the special resin lubricating layer are suitable for higher PV values, have lower friction factors and excellent wear resistance. The linear speed can reach 5m/s during rotary motion and the PV value can reach 60N/mm2*m/s. This material is mainly used for working conditions that require lubrication.
  Material organization
  1. The thickness of PTFE/fiber mixture is 0.01~0.03mm. As a material layer in contact with the grinding shaft, a good transfer film can be formed to protect the grinding shaft, which provides the self-lubricating performance of the bearing.
  2. The copper powder layer is 0.20~0.35mm, which has good load-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.

  Technical Parameters


Static bearing 250N/mm2 Coefficient of friction 0.03~0.20
Low speed operation 140N/mm2
Rotation, rocking motion 60N/mm2 Line speed Dry friction 2m/s
Fluid lubrication >5m/s
PV value (dry friction) Intermittent operation 3.6N/mm2*m/3 Thermal Conductivity 42W(m*K)-1
Long-term operation 1.8N/mm2*m/3
Operating temperature -195℃~+280℃ Linear expansion coefficient 11*10-6*K

  typical application:
  SF-1T oilless lubricating bearing (special for gear pump) is newly developed for high PV value applications under fluid lubrication conditions, mainly used in gear pumps, vane pumps, shock absorbers, gearbox motors, piston pumps, etc.
