Composite plain bearings,SOB SOBU bronze straight type guide bush are suitable for high speed and heavy loads.The bearings are primarily used to support the shaft and on-axis components, and to adhere to the rotational precision of the shaft to slide the bearings and reduce the conflict and wear between the shaft and the support. Commonly used bearings are primarily rolling bearings and.
