NSK bearings when loading and unloading work pay attention to the point

NSK bearings when applying when installation need to pay attention to the following several points: ( 1) Work together as much as possible through the axis of the bearing, this requires the screws even symmetry and smooth, by spherical or parallel to the axis force application. ( 2) Wire should be smooth and uniform, the size of the unfavorable impact, this request can use hydraulic or use steady pull or pressure tool, it had to use hammer, also want to through soft without exfoliation metals such as copper sleeve to buffer, tapping force as gently as possible. It is best to use copper or copper hammer hammer. ( 3) Avoid by applying pressure roller, which requires the inner ring (installation Axial circle) When applying pressure through the inner ring and outer ring installation) Through the outer power works. ( 4) The extent of the drag force continued to be, for example, when installing a bearing NSK bearings to fit into the correct position to stop work, guarantee the ring ( Washers) The end face of landing on a hole or shaft shoulder end, neither packed too tight, nor does not reach the designated position. The installation of NSK bearings must be 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. NSK bearings before installation should be clean, dry after use, and to ensure good lubrication, grease lubrication, commonly used bearing lubrication may be adopted. Using grease lubrication, should choose without impurities, antioxidant, antirust, superior performance, such as extreme pressure grease. Grease filling quantity for bearings and bearing box - 30% of the volume 60%, unfavorable and overmuch. 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. NSK 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 In the case of a small amount of interference, but at room temperature with the sleeve pin imported bearing ring end face, with a ð ¨ +  head banging on sleeve, through the sleeve ring is balanced 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.
