Beyond Bearings: Enhancing Performance with Polymer Coatings

 

PTFE Composite Bronze Gleitlager Structure

steel backed ptfe conposite bushing

 

 

  • 1. PTFE/Pb mixture 0.01~0.03mm as sliding layer, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming homogeneous oxide type solid lubricant film.
  • 2. Porous bronze 0.2~0.3mm, provides Max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE-lead mixture.
  • 3. Low-carbon steel backing 0.7~2.3mm, provides fundamental structural support and gives exceptionally high load carrying capacity, excellent heat dissipation.
  • 4. Tin-plating 0.005mm or copper plating 0.008mm, provides good corrosion resistance.

 

PTFE Composite Bronze Gleitlager Characteristics

 

  • · Good wear and friction performance over a wide range of loads, speeds and temperature without oil
  • · Also perform well with lubrication
  • · Maintenance-free, long life

 

Availability

 

  • · Standard cylindrical bushings, flange bushings, thrust washers and straps available.
  • ·Lead-free type is also available
  • · All special designs are made according to your requirements.

Rolled bearings are based on high-quality cold-rolled steel plates with porous spherical bronze powder sintered in the middle, and then a mixture of polytetrafluoroethylene (PTFE) and fibers is sintered on the surface of the porous spherical bronze powder layer, and the rolled sliding Bearings.
This product has the characteristics of small friction coefficient, wear resistance, good corrosion resistance and self-lubrication. The use of this product can reduce the cost, reduce the mechanical volume, avoid the occurrence of shaft biting and reduce mechanical noise.
This product has been widely used in various mechanical sliding parts, such as printing machines, elevators, textile machines, tobacco machines, fitness machines, hydraulic vans, micro-motors, solenoid valves, automobiles and agricultural and forestry machinery.

Factors Affecting Life

 

1: Load P: The larger the load, the shorter the bearing life; in any case, the maximum load must not exceed the theoretical maximum allowable load.
2: Speed V: The higher the speed, the shorter the bearing life; in any case, the maximum sliding speed cannot exceed the theoretical maximum allowable value.
3: PV value: The working life of the bearing depends on the PV value, that is, the product of the actual load P and the sliding speed V. The smaller the PV value, the longer the bearing life.

wo
4: Temperature: The life of the bearing also depends on the temperature at which the bearing is used. The higher the temperature, the shorter the service life of the bearing. Therefore, the heat dissipation characteristics of the relevant components should be considered in the design selection.
5: Surface roughness of the grinding parts: When the grinding parts are made of alloy steel or hard chrome-plated shaft, the bearing life can be significantly improved when the surface roughness Ra=0.4-0.63.
6: Other factors such as bearing housing design, lubrication conditions, etc.
