Small Expansion Coefficient Oil Brass Bushings High Bearing Capacity

Brass-Wrapped Bushings Bearing Oil Free Bushing Oilless Bearing

JS-091 is similar with JS090,except for:replace bronze with copper CuZn31Si(H68) or CuZn37Si(H62),to save the costs,ecomonic & more loading capicity.

Application characteristics:

1. Advantages of light weight and low cost,for compact application,easy fittling;
2. Oil holes stored more oil or grease, then extanded service life and lubrication intervals than normal MQ-090 type bushings.
3. High bearing capacity, especially can match the shafts with rough surfaces;
4. Extraemely high heat dissipation, small expansion coefficient, stable use, long service life;
5. Excellent wear resistance with lower friction;
6. Chemical resistance.
