Sliding sleeves are used for joints that require free movement of shafts or other rolling elements.The sleeve is made of composite or metal with self-lubricating material ptfe inserts.Usually, they do not require additional lubrication.
PTFE sleeve – a sleeve made of steel tape with pressed PTFE composite material.They also provide collar bushing.

Collar Bushing Characteristics
The PTFE-based sliding surface allows smooth running without friction without lubrication. The presence or continuous feeding of oil or other non-aggressive fluids can be beneficial and improve the performance of these bearings.
Lead-free bearing is a new product developed on the basis of PTFE material according to international environmental requirements.This product is widely used in general machinery, especially in food machinery, pharmaceutical machinery, tobacco machinery.
Collar Bushing Material
Tread material: Polytetrafluoroethylene (PTFE)

Collar Bushing Bushings Lubrication
The PTFE-based sliding surface provides smooth operation with a low coefficient of friction without lubrication. During the short run-in phase, there will be some transfer of the PTFE material from the sliding contact surface to the opposite surface. After this transmission, the characteristic properties of these bearings with a low coefficient of friction and wear will be achieved.
The presence or continuous supply of oil or other non-corrosive fluids can be beneficial and improve the performance of these bearings.
Collar Bushing Advantages
- PTFE, fiber mixture in motion can form a good transfer film to protect the grinding shaft.
- Because it does not contain lead, it is harmless to humans.
- It has good load capacity and wear resistance.
- Copper and steel plates have good thermal conductivity.
- The coating on the surface has good corrosion resistance.

Collar Bushing Application
PTFE composite bushings are suitable for applications where sliding material with self-lubricating properties is required.Application area examples for these bushings are:
- automotive
- material handling equipement
- home appliances and consumer goods
- textile machinery
Bushing Bearings have been widely used in food machinery, medical machinery, tobacco machinery, beverage machinery and other green machinery.With the gradual development of international environmental protection, the replacement of sleeve parts.
