Oil Free Bearing Wrapped Bronze Bushing Oil Free Bearing Oilless Bushing
Wrapped bronze bushing, using tin bronze alloy CuSn8/CuSn6.5 for material, with oil holes according to a certain angle, easy to form oil film at startup, thereby reducing startup & running friction coefficient.
It has good bearing capacity, corrosion resistance and wear resistance. This series of products are widely used in agricultural machinery, forestry machinery, construction machinery, construction machinery and other high load low speed occasions.
Product characteristics:
1. The 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. Extremely high heat dissipation, small expansion coefficient, stable use, long service life;
5. Excellent wear resistance with lower friction;
6. Chemical resistance.
