The collar with CuSn8 bronze backing a metallized dickers high bearing high, wear-resisting performance good economical bearings. The standard FB092 product work surface dissatisfaction rules of diamond oil hole, plays the role of reservoirs, is at the beginning when motion can more easily oil film so as to reduce the formation of initial friction coefficient. Mainly USES agricultural machinery, construction machinery contour load capacities occasion.
