Possible minimum inner diameter 6mm, maximum outer diameter 1500mm.

Possible shape include bush, flange bush, half bush, ball, gasket, slide plate, L and V special shape etc.

Working principle：

The product is based on high quality copper alloy, inlaid the solid lubricant according to a certain angle and proportion(normally 15-30% of surface area, do not affect the working strength but realize the lubrication function), and machining by precision machine.

When the bearing is working, the linear expansion coefficient of metal and solid lubricants is obviously different due to the friction heat.

Lubricants will form solid lubrication film on the working surface to achieve the effect of self lubrication and maintenance free.

Selection conditions:

1 - low speed and heavy loading, oil lubricating film can not maintain.

2 - High or low temperature working, or ambient temperature change a lot.

3 - Working in corrosive medium such as sea water or other chemical liquids.

4 - The impact load is easy to appear in the work.

5 - Need to start frequently or start at high load.

6 - Long maintenance period or high maintenance cost, which requires long working life.

7 - It is difficult for lubricating oil to be supplied because of the working environment or mechanical structure.

Main application areas:

The product is mainly used in hydroelectric generating units, reservoir operation doors, accident doors, petroleum machinery, metallurgical equipment, mining machinery, aviation industry, plastic machinery, automobile production line and other fields.

Packing and delivery:

Packing with bubble bag in wooden carton on the pallet, delivery by air or sea.
