High Temperature Bimetal Bearing Steel Bronze Bimetal Sintered Sliding Bearing
What is bimetal bearing?
Bimetal sliding bearings are made from bronze and steel alloy. The soft bronze inner layer can provide good lubricating performance with oil grease, hard steel back can provide good support on the whole bearing and cut down the cost.
These
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 bimetal 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
- High strength and good lubricating required,like engine,gear pump,oil pump
- Space is limited.
Why choose bimetal bearing?
- Maintenance-free operation
- Minimum wall thickness, minimum space requirements
- Accommodation of heavy loads
- Wide range of temperatures
- Good sliding properties
- Virtually no stick-slip
- High wear resistance
- These bearing can applied with precision machining tooling
