NSK bearing removal equipment installation and equipment repair fitter job often encounter. You must select the correct removal method, use the appropriate removal tool, part of the force at a reasonable, may successfully completed the demolition job, and ensure that NSK bearings are not damaged.
　　1. removal considerations
　　① understand the removal of the NSK bearing its original course and work with nature, have working hours.
　　② by NSK bearing size, type, construct specific conditions, such as removing the Bearing Assembly tools, such as demolition, Jack, oxalis corymbosa, Plumb, Rod, etc. Sometimes there is the need for a removal of NSK bearing specific conditions temporarily make a one-time removal tool.
　　③ Remove NSK bearings from the shaft, apply evenly on the bearing inner ring, remove NSK bearings from bearing boxes, to force evenly for NSK bearing on the outer cylinder.
　　④ When confronted by NSK bearing Assembly interference is large and there are circumstances such as rust, removing difficulties and avoid not hard and fast disassembly, use heating solution.
　　⑤ NSK bearing retainer, dust cover and seals can be easily deformation, not applying pressure on them.
　　2. removal method
　　A press force bearing removal: press force demolition is undoubtedly the best method of NSK bearings, such a pressure and pressure into smooth, accurate speed control, force direction merits removal in NSK bearing down on the mat to half the combined pad, press force on shaft end.
　　B Rama (demolition) force NSK bearing removal: Rama, commonly known as scratching, it has 3 feet and 2 feet in two ways. Claw when used to adjust the distance between the right and point of application of force on the inner ring.
　　Double tie rod Remover remove NSK bearing used in c: a homemade pair of tie rod remover, used when the lever is moved to the same length on both sides, remove the screw on the hub and axle Center in a straight line. And then slowly rotate the screw to be demolished. The disadvantage of such a device is the removal of the part size is fixed is not adjustable, and force the direction of offset.
　　When removing larger size or the degree of interference to the larger of NSK bearings, because of larger axial forces, apply hard pressure, one may divide NSK bearing bad, the second is imposed if a large axial forces, bearing may barely be removed, but serious injury journal. In this case, use heating solution. Using materials such as asbestos rope wound on to no heating on an axis, cut off heat, in hot oil, hot water or steam to heat the bearing, NSK bearings have a slight expansion of a demolition, the heating temperature should be controlled at about 100 ° c.
