NSK bearings installation must be carried out in a dry, clean environment under the condition of. Prior to installation should carefully check the shaft and housing mating surfaces, convex surface of the shoulder end surface, grooved, and connection quality. All tie in with the surface of the connections must be carefully cleaned and remove the Burr, cast NET sand rough surfaces must, inter alia.
NSK bearing install gasoline or kerosene before cleaned, dried and then used and ensure good lubrication, bearing grease lubrication and oil lubrication can also be used. When grease lubrication should use non-anti-oxidation and impurities, Rust prevention, extreme pressure grease for superior performance. Grease filled bearing and bearing box of volume-30%, not too much. Double row tapered roller bearings with sealing structure and water pump bearings good grease filled, users can use directly, no longer subject to cleaning.
NSK bearing install, you must exert equal pressure on the circumference of the ring face, ring push, do not use lang the first percussion tools directly NSK bearing end, so as not to damage the bearing. In the case of less interference, can be pressed at room temperature with sleeve NSK bearing ring face, using hammer tapping sleeves, rings balanced through the sleeve is pushed. If the mass installation, to be used in hydraulic presses. When pressed, should guarantee the outer ring side face and the shell shoulder end surface, inner ring and shaft shoulder end surface clamping, gaps are not allowed.
When interference is large, can be oil-bath heating or induction heating method of NSK bearing install, heating temperature range of 80 ° c-100 ° c, the maximum cannot exceed 120 degrees centigrade. At the same time, nut fastening NSK bearings or other appropriate methods to prevent cooling of the bearing width shrinkage after leaving gaps between ring and shaft shoulder.
NSK bearing rotating test shall be performed after installation, first used for the axis or NSK bearing boxes, without exception, no load power, low speed operation, and then depending on operation gradually increase the rotation speed and load, and detect noise, vibration and temperature, unusual, should stop and check. Running test after normal delivery.
