DU/DX Bushing Oil-less Dushing Dry Bearings

 

 

What is composite bearing?

 

 

 

Composite dry sliding bearings are primarily used for bearing arrangements where heavy loads have to be supported and where rotational or oscillating movements are relatively slow.

 

 

 

Where to use composite bearing?

 

 

 

• Because of their good sliding properties and compact design, these plain bearings are particularly suitable for bearing arrangements where:


• Maintenance-free operation is a prerequisite


• There is a risk of lubricant starvation


• Lubricants cannot be used or are forbidden


• Space is limited.

 

 Why choose composite bearing?

 

• Maintenance-free operation


• No lubrication required (PTFE composite)


• Initial lubrication required (POM composite)


• Minimum wall thickness, minimum space requirements


• Accommodation of heavy loads


• Wide range of temperatures


• Good sliding properties


• Virtually no stick-slip


• High wear resistance


• Less sensitive to edge loading (POM composite)


• No machining required 

 

 

 

Which kinds and sizes we have?

 

 

 

The standard range of composite plain bearings is very comprehensive and covers almost every standard size. This range comprises straight and flanged bushings, thrust washers and strips.
