KOYO import bearing installation steps and matters needing attention

KOYO import bearings should be taken before installation with petrol or kerosene wash clean, dry after use, and to ensure good lubrication, KOYO import bearings commonly used grease lubrication, lubrication may be adopted. Using grease lubrication, should choose without impurities, antioxidant, antirust, superior performance, such as extreme pressure grease. With sealing structure of double row tapered roller bearing and water pump shaft bearing has good filling grease, users can directly use, shall not be clean. Grease filling quantity for bearings and bearing box - 30% of the volume 60%, unfavorable and overmuch. KOYO import bearings when installation, must equal pressure on the circumference of the ring width, to press the ring into, can not use ð ¨ +  top tools directly on bearing face, in order to avoid damage If large quantities of installation, can use hydraulic press. Fashionable, should guarantee the outer end face and the shell shoulder end face, inner ring end face and the shaft shoulder end face pressure, there is no gap. In the case of a small amount of interference, but at room temperature with the sleeve pin bearing ring end face, with a ð ¨ +  head banging on sleeve, through the sleeve ring is balanced When large amounts of interference, can use oil bath heating or inductor heating method to install the KOYO import bearing, heating temperature range of 80 ℃ - More than 120 ℃, 100 ℃, the highest can't. At the same time, nut or other appropriate method is applied to tighten the bearing, in order to prevent the bearing width after cooling contraction and make the ring gap between shoulder and produce single row circular cone roller bearings installed last should undertake clearance adjustment. Clearance value should be used according to different conditions and cooperate with the amount of interference and specify the size. When necessary, shall be tested to determine. Double row tapered roller bearing and water pump shaft bearing in have been adjusted when delivery from factory clearance, installation time don't have to adjust. KOYO bearing installation: the installation of the bearings must be conducted in a dry, clean environment conditions. Before installation should carefully check the shaft and the shell surface, convex shoulder of end face and groove and the connection surface machining quality. All matching connection surface must be carefully cleaned and remove burrs, rough surface must remove all sand castings.
