SF-1PI

SF-1PI oil-free bearing is based on low carbon steel plate as the matrix, the surface is sintered spherical bronze powder, and then a layer of polyimide (PI) modified PTFE material is laid on its surface, and the plate is rolled into a shape and made into a bushing and other types. Because polyimide is a high mechanical strength organic polymer material, can withstand high-strength alternating load, good fatigue resistance, and non-absorbent, corrosion resistance, so the product is very suitable for automobile belt tensioner and other large load, frequent changes of swing occasions; And polyimide material has good thermal stability and can be used for a long time at 300 °C, so the product can also be used in high temperature occasions such as electronic baking.
