RST-FB090 Bronze-Wrapped Bearings

    Material Structure

    The bearings are wrapped of a cold formable homogenous bronze (CuSn8P0.3 & CuSn6.5P0.1), which will obtain exceptional material properties. The standard size are fitted with diamond shaped lubrication indents on the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film in the start movement and reduce the start friction.

Appliation

Appliation

  1. The inside surface of the products inside surface is full of diamond oil indention, which can stock grease.
  2. Minim oil lubrication, can be applied in water-lubrication environment
  3. Good anti-abrasion, low coefficient of friction, long operating life.
  4. Can work consecutively at 100℃~+200℃.
  5. Good mending, low-noise, non-pollution.
  6. This wall, light, can reducing the volume of the machine.
  7. High density, high load, no alveoli.
