Hydraulic Bushing

Definition

SF-1 Oilless bushing is a sliding bearing made of steel plate as the substrate, sintered spherical bronze powder in the middle and rolled polytetrafluoroethylene (PTFE) mixture on the surface and rolled. It has a small coefficient of friction, wear resistance, good corrosion resistance and oil-free lubrication. The use of this product can reduce the cost, reduce the size of machinery, avoid the phenomenon of biting the shaft and reduce mechanical noise and other advantages.

 

Revolutionary technological advantages

Permanent lubrication free: Patented PTFE/ graphite composite material completely eliminates the need for lubrication

Extraordinary wear resistance: The wear rate is only 1/5 of that of traditional copper sleeves, and the service life is increased by 800%

Intelligent adaptive: Gradient lubrication technology, automatically adjusting the release of lubricant according to the load

Extreme working condition expert: Stable operation from -50℃ to +280℃ (instantaneous 350℃)

 

Analysis of the six-layer composite structure

1. High-strength base: Super strong steel base

2. Porous transition layer: 25% porosity oil storage structure

3. Nano-reinforcing layer: Carbon fiber reinforced PTFE

4. Surface texture layer: Laser micro-pit oil storage design

5. Anti-corrosion coating: Tin plating or DLC coating is available as options
