Self Lubricated Bush Bearings
Sintered Bronze / Iron Sintered Self Lubricated Bushes
Dry Bushes & Washers
Graphite Filled Bronze Bushes
Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.
1. POM thickness 0.30~0.50 mm. It provides high wearresistance and
low friction even with only minute volume oflubricant are supplied,
this bearing surface carries a pattern of circular indents which
should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 0.20-0.35mm. A special
composition of powdered copper is thermally fused to the steel
backing. This contact layer acts as an anchor for the PTFE layer
and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and
heat dissipation characteristics.

Metric bearings and imperial bushings made to order: standard
bushing forms in special dimensions, half-bushings, special shapes
obtained by stamping, bearings with locating notches, lubricant
holes and machined grooves, customized bushing designs
Recommended for applications involving intermittent operation or
boundary lubrication... Automotive: suspension joints, kingpin
assemblies and stub axles of trucks, automobile driving joint
hinges, steering and other linkages, articulation joints, rear
chassis hinges, fair leader rollers... Machine tool building
industry: spindles in drill, grinding, and milling machines, ram
guide plates in multi-ram 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... It is especially
well-suited for applications where lubricant can not be supplied
continuously or repeatedly.
