70N/mm² Wear Resistant Steel Backed PTFE Lined Bushings
Marginally lubricated bushings for grease or oil lubricated
Standard parts contain grease indents in the sliding layer; plain
sliding layer available by request
Optimum performance under relatively high loads and low speeds
Suitable for linear, oscillating and rotating movements
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
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

sewing machines, etc.
Dental equipment, X-ray equipment, medical turntables, wheelchairs,
Lift components, excavators, concrete mixers, caterpillars,
Valves, blinds, drying plant, baking machinery, screws and bolts,
It can substitute a conventional bearing where saving space is
Steel Backed Bushing provides superior shock and impact load
resistance. The Steel Backed PTFE Lined bushing maintains a low
friction and is usable without lubrication at high load, low speed
operations with excellent wear resistance.
