● Installation method of forklift mast bearing
The commonly used installation method of mast bearings is the shaft fixed with the matching retaining ring. The matching between bearings and shafts is generally transitional matching, and the tolerance of shafts is g6 or h6. The axial direction is limited by the standard shaft retaining ring. In addition, there are also half-hole bearing screw fixation, shaft fit gland fixation, and other methods.
