DX Lead-free boundary lubrication bearings

MATERIAL STRUCTURE

1. POM 0.03-0.50mm, anti abrasion, low friction coefficient even no oil given. The inside of the bearing are full of indentions, which need to be filled with grease before installing.
2.Bronze powder layer, 0.2-0.35mm, high load capacity and anti-abrasion, good thermal conductivity, which also further strengthen the combination of the POM layer and steel plate.
3. Low carbon steel, which improved, load capacity & thermal conductivity.
4. Copper/Tin plating layer, 0.002mm, anti-corrosion.

TECHNICAL DATE

Max load	Static load	250N/mm2	Operation temp.		-40℃~＋130℃
	Low-speed rotation	140N/mm2	Max Linear Velocity	Grease lubrication	2m/s
	Rotation、oscillation	70N/mm2		Keep to supplying oil	>2m/s
Max PV		3N/mm2.m/s	Thermal conductivity		4W(m.K)-1
Coefficient of thermal expansion		11x10-6K	Friction coefficient		0.05~0.20

APPLICATION CHARACTER

The product can be used under high load with low speed, rotation, oscillation, and also can be applied in no liquid lubricants environment that switches frequently with load; the part can work with out oil, and will have a long operating life if oil giver; the POM layer can be machined during installing, which does benefit to the mating.
The products now mainly used in metallurgy machine mine industry, irrigation machine, agriculture machine etc.
