DU Composite slide Bearing

What is DU 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 DU 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 du 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.
