MQ-090/092 BRONZEWRAPPED(FB series) Bushing
Application characteristics
1. The advantages of light weight and low cost,for compact application,easy fitting;
2. Oil pockets stored oil or grease, then the time for apply oil is extended over 5 times than the ones of general copper sleeve;
3. Extremely high bearing capacity, especially can match the shafts with rough surfaces;
4. High heat dissipation, small expansion coefficient, stable use, long service life;
5. Excellent wear resistance with lower friction;
6. Chemical resistance.
Material structure
Use high density bronze strips to roll the spherical oil pockets, in order to reduce wear, prolong the use time, good corrosion and protection function.
