Biscuit, bread and so on bake. Oven (oven) door hinge bushing. Chain joint bushing, automatic food (fast food) package. Filling machine sealing.Incision.Feeding transmission mechanism.
The development of self-lubricating composite bearing and trend of inlay material are widely used on the Food packaging. Filling machinery.
The result shows that the compound ptfe material bearing sliding bearing surpass the ball bearing in endurance to pressure, adaption to variable temperatures and life for use and so on.
There is a large space to explore in the area to reduce friction and increase the load supportcapacity of a sliding bearing with composite surfaces.
Our bimetallic bearing material and combination technology.
self lubricating bearings have superior in some performances to DU bearings.
The present concept can be used not only to design a more outstanding journal bearing but also to design a thrust bearing or a slider bearing with an outstanding performance.
We are a manufacturer of steel bronze ptfe three-layer composite oilless lubricating bearings.

· 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 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.

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.
