Oilless bushings, also known as sleeve bearings, are a type of self-lubricating sliding bearing. Oilless bushings are used to support sliding motions by reducing friction and increasing stability. Because of their self-lubricating properties and versatility in terms of usage, oilless bushings are a very popular component in industrial applications. Oilless bushings are cylindrical and can be made in any girth and length.
The modern design that is used in today’s oilless bushings has made them extremely popular. The fact that oilless bushings require no maintenance makes them very convenient, and their self-lubricating properties make them long-lasting and highly efficient.
PTFE composite straight (cylindrical) bushings are suitable for oscillating, rotating and linear movements, and can accommodate radial loads. Despite their thin-walled design, they can accommodate heavy loads. They also provide good heat dissipation, therefore enabling relatively high sliding velocities.
- Maintenance-free operation
- Cost-effective with long service life
- High operating temperatures
- High load carrying capacity
- High sliding velocity and small operating clearance

| Materials |
| SF-1 | SF-1 is a kind of oilless Slide Bushing made of the polytetrafluroethylene(PTEE) composite material,Which is a copper-plated steel plate on to which a porous layer of tin bronze powder is sintered and also a mixture of PTFE and lead are filled into and covered the porous layer by a roling process. |
| SF-2 | SF-2 is a boundary lubricating bushes made of the POM composite material, which also has a copper-plated steel plate on to which a tin bronze powder is sintered, modified polyformadehyde resin(POM) is firmly anchored in the sintered bronze layer. The surface of covering layer has many pockets to retain lubricating grease. |
Customized bearings
We can design the bearing according to your required types,sizes and application.
If you have drawing and datasheets, it is better. We will produce the bearing according to your drawing and datasheet totally.
