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.
