COMPLETE CATALOGUE Bushing 23BK-1 257 Items

Composite PTFE sliding bearings are necessary to create a long service life as working hours and avoid frequent maintenance due to their low friction. Sliding bearings solve the problem of premature bearing failure under heavy loads and applications or at limiting speeds. The bushings consist of two materials, steel is bonded with PTFE, which allows low bearing wear and a dissipating effect of the heat developed in friction. 

Applications can be:
-Automotive
- Earthmoving 
- Textile machinery 
- Handling machines 

The strength of this article is the low or zero maintenance for operation. High temperature heavy duty, high speed applications.
