Influences on the service life:
Wear and service life of the CSB slide bearings are dependent
on the following:
● Specific bearing load
● Sliding speed
● PV value
● Roughness depth of the mating surface
● Mating surface material and
● Temperature etc. and so on
|
|
| During running-in, some
of the surface of the PTFE/Pb or solid lubricants is transferred
to the mating surface. A running surface is formed which has
low coefficient of friction and this has a positive effect on
the operating behaviours. For 3-layer dry bearings, after running-in,
some of the porous bronze layer can be seen on the sliding layer
as individual areas of different size. This shows that the bearing
is functioning correctly. |
 |
| The PV value has a considerable
influence on the bearing service life. It is the product of
the specific load P and the sliding speed V and the PV is very
important design data, we recommend design lower PV value will
leads to a longer service life. |
