SPF material is made with high strength copper alloy, and the inserted solid lubricant materials are made with graphite and PTFE.
According to the bushings' working conditions, the bronze combination between different metal basement and various solid lubricant can ensure that the product can peform under various temperatures, loads, movements and medium as required.
Oilless bush is especially applied in oil-free high temperature, high load, low speed, contamination resistance, corruption resistance radiation resistance as well as the use under such special work conditions that cannot be lubricated, such as underwater and in vacuum space.
1. May work without any oil for long period.
2. Extremely high load capacity, good anti-wear and low friction.
3. Particularly appropriate for low speed and high load.
4. Suitable single direction axial loads
5. Free design is possible on the shape and size
6. Can be used in wide range of temperature, from － 40℃＋ 300℃
