70N/mm² Wear Resistant Steel Backed PTFE Lined Bushings


  1. Marginally lubricated bushings for grease or oil lubricated applications

  2. Standard parts contain grease indents in the sliding layer; plain sliding layer available by request

  3. Optimum performance under relatively high loads and low speeds

  4. Suitable for linear, oscillating and rotating movements

  5. Wide range of parts available from stock

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.

Typical Applications

BEARINGS bushings can be widely used as components necessary in mechanical industries or for repair and maintenance of various machines.
Automotive industry:
Wiper arms, door hinges, trunk hinge, foot pedals, shock absorbers, enines, camshafts, connect rod, steering system, pedal assembly, seat angle regulator, etc.
Office machines:
Copy machines, fax machines, joint and reciprocation parts of faxed, paper shredders, scanners and printers, starting and hinge parts of fitness equipment, doors and windows.
Agricultural machinery:
Planting machines, mills, potato harvester, tractors, etc.
Paper/wood/pulp industry:
Timber- & chain-saws, cutting machines, folding machines, looms, tec.
Steel industry:
Sliding plates, steel & rooling-mills, body presses, tool posts, etc.
Electricity tools:
Switch gearsm contactors, pneumtools, hydraulic tools, transformers, etc.
Domestic appliances:
Microwave ovens, food processors(mixers, blenders), lawn mowers, sewing machines, etc.
Medical equipment:
Dental equipment, X-ray equipment, medical turntables, wheelchairs, etc.
Construction industry:
Lift components, excavators, concrete mixers, caterpillars, escalators, etc.
Other used:
Valves, blinds, drying plant, baking machinery, screws and bolts, awnings, etc.
It can substitute a conventional bearing where saving space is desired.
Steel Backed Bushing provides superior shock and impact load resistance. The Steel Backed PTFE Lined bushing maintains a low coefficient of
friction and is usable without lubrication at high load, low speed operations with excellent wear resistance.
