The steel ball sleeve is mainly composed of matrix + steel ball, and the matrix is processed into a number of regular holes according to industry standards, and the steel ball is installed in it, and the steel ball can move flexibly and is not easy to fall off.
Cage bearings
The steel ball adopts GB308-84 precision G10 standard, the tolerance and roundness of the steel ball are within 0.0025mm, and the hardness is 64~64HRC. The steel ball sleeve has high-precision axial motion and radial movement, and the interference fit is used with the shaft and sleeve, which can achieve backlash-free assembly and extremely high combination accuracy, so it is widely used in the mold industry, machinery and equipment industry, and high-precision operation or movement industries.
