· marginally lubricated bushings for grease or oil lubricated
applications
· 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 shock loads.
1. POM thickness 0.30~0.50 mm. It provides high wear resistance 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.
