Bearing FAQ

Whether the bearing is installed correctly directly affects the accuracy, life and performance of the bearing.
  • Q Bearing Installation Tips
    • using copper bar and manual hammer installation
    A simple way to install medium - sized bearings. When the bearing inner ring is tight and the outer ring is loose, the copper rod is pressed to the end face of the bearing inner ring, and the copper rod is directly struck by hammer. The bearing is then loaded onto the shaft through the force transfer.

    • use socket installation
    Press the sleeve directly on the bearing end face, and strike the copper sleeve with a hammer. The sleeve shall be made of soft metal.If the bearing is installed on the shaft, the inner diameter of the sleeve should be slightly larger than the journal, and the outer diameter slightly smaller than the flange diameter of the bearing inner ring. If the bearing is installed inside the bore, the outer diameter of the sleeve should be slightly smaller than the outer diameter of the bearing.

    • press pressure into laws
    Mounting pressure should be applied directly to the end face of the bearing ring with interference fit. Otherwise, it will cause compression injury on the working surface of the bearing, resulting in rapid damage of the bearing.
  • Q Installation Considerations
    • have clearance fit, the bearing ring Suggestions on the fitting surface coated with a thin layer of preservatives, prevent the friction between mating surface corrosion.
    • when installation on bearing force, not by pass from a roller bearing ring to a bearing ring, otherwise it may cause damage to the race.Do not directly hit the bearing ring, retainer, roll or seal.
    • eccentric sleeve.The eccentric sleeve is first set on the eccentric step of the bearing sleeve, and is first tightened by hand; then the small iron bar is inserted into the sunken hole of the eccentric sleeve, and the small iron bar is struck with the hand hammer in the direction of rotation, so that the eccentric sleeve is installed firmly, and finally the screw on the eccentric sleeve is locked.
    • fixed bearing bolts do not tighten, then good bearing bolts.The bearing and seat on the other end of the same shaft shall be installed, and the bearing shall be adjusted to the correct position automatically before finally tightening.
    • coating on surface of the bearing and the bearing lubricating oil, put the bearing into the bearing seat.The assembled bearing is then sleeved on the shaft together with the bearing seat and pushed to the required position for mounting.
    Correct installation of bearing can not only increase the service life of bearing, but also greatly improve production efficiency.
