The bakelite bearing bush has the advantages of high temperature resistance, low temperature resistance, corrosion resistance, weather resistance, high insulation, high lubrication, no adhesion and no toxicity. Good mechanical properties, sufficient compressive strength and fatigue strength, small modulus of elasticity, uniform compression, no deformation bakelite bearing system, widely used in steel binding machine. Used by large and medium-sized steel mills. Our factory produce bakelite bearing bush has a long history, complete equipment, advanced technology, strong technical force, complete testing instruments, our factory production bakelite bearing bush economical and durable, convenient maintenance and replacement, downtime is short, greatly improve the operation rate of the mill
Product features:
1, can save a lot of non-ferrous metals, such as copper, aluminum, tin, lead, etc.
2, have good mechanical properties, have enough compressive strength and fatigue strength, elastic modulus is small, can absorb vibration, does not break the roller, bearing shell surface pressure is uniform, does not deform.
3. the friction coefficient is small, and the power loss is reduced by 15 - 20 % compared with the metal.
4, no matter under what circumstances, will not lose the shaft head. And when in use, the shaft head is polished to improve lubrication conditions.
5, the lubricant is convenient to use, tap water and emulsion can be used, and the cost is reduced. 6, compared with the bearing plate, a large amount of cotton cloth is saved, the utilization rate is improved, the machining program is saved, and the cost is reduced.
Scope of application:
This product is suitable for the country 's major, medium and small iron and steel enterprises.
Production scope: ball mill bearing bush, 550 bearing bush, 250 bearing bush.
