CSB-EP Plastic compound
bearings
|
Structure |
|
|
New economic self-lubricating
bearings made by kinds of resin with additive fibre as base
material produced by injection molding machines. The application
for high load with lower speed and lower friction request, like
automotive industries, lift machineries, copier, OA machines,
sports machines, food industries, chemical machines etc. compare
with the metal bushes, the weight and cost is much lower. Suite
for large production with low cost and short delivery time.
|
|
|
Features |
|
|
1. Design for dry and
maintenance-free
2. Lower friction, excellent wear resistance
3. Higher load capacity
4. Excellent chemical resistance
5. Lower moisture absorption
6. Thin wall thickness design, reduce the space and weight
7. Can reduced cost when mass production
8. No special request for matting material |
|
|
Material
selection |
|
|
The user can select the
bearing by temp. of work environment, wear resistance request,
moving method, installation method, the cos of the material
etc. Normally the temp., load and PV value should be firstly
consideration. We recommend design lower PV value will leads
to longer service life. Please select the correct one refer
the attached material table. |
|
|
Bearing
Installation |
|
|
we recommend the housing
as H7 and the shaft as h9. The ID shown in the size table is
after fitting in the ring gauge(0.002mm). The bearing, housing
and fitting tools must be kept clean during fitting. To make
the fit easy should be have the chamfer on the housing and shaft,
if possible the pre-lubrication is much better for getting lower
start friction. |
