structure
|
|
1. POM 0.03-0.50mm, anti abrasion, low
friction coefficient even no oil given.
The inside of the bearing are full of indentions, which need to be
filled with grease before installing.
2.Bronze powder layer, 0.2-0.35mm, high
load capacity and anti-abrasion, good thermal conductivity, which
also further strengthen the combination of the POM layer and steel
plate.
3. Low carbon steel, which improved, load capacity & thermal
conductivity.
4. Copper/Tin plating layer, 0.002mm, anti-corrosion.

APPLICATION CHARACTER
|
|
Recommended
for applications involving intermittent operation or boundary
lubrication...
Automotive: suspension joints, kingpin assemblies and stub axles
of tucks, automobile driving joint hinges, steering and other
linkages, articulation joints, rear chassis hinges, fairleader
rollers...
Machine tool building industry: spindles in drill, grinding, and
milling machines, ram guide plates in multiram
presses...
Agricultural equipment: gearbox, clutch, bale trips and wheel
caster swivels for bale accumulators, front axle pivot bearings,
steering idler box bearings and kingpin bearings for harvesters...
Be especially well-suited for applications where lubricant can
not be supplied continuously or repeatedly
