Installation of tapered bore bearings tapered bore bearings can be mounted directly on the tapered journal has engraving machine spindle bearing, or mounted on an adapter sleeve and withdrawal sleeve tapered, tightness of the blending of the available bearing radial clearance reduction a small to measure. Therefore, the installation should measure the bearing radial clearance, the installation process should be measured regularly clearance clearance reduction to achieve the desired date. When installing commonly used thin jam nut mounting bearing 20 * 25 * 4, may also heating installation methods. First, bearing installation: installation of bearings must be carried out in a dry, clean environment conditions. Should be carefully examined with the surface of the shaft and housing, face shoulder, processing quality grooves and connecting surface before installation. All mating connector surface must be carefully cleaned and remove burrs, casting a net addition to the raw surface must be sand. Bearing installation should be preceded by cleaning with gasoline or kerosene clean and non-standard bearing 16 * 31 * 10 dry before use, and to ensure good lubrication, bearings are generally lubricated with grease, oil lubrication can be. When using grease lubrication should be used without impurities, oxidation, rust, extreme pressure grease with superior performance.
