SKF bearing in installation of  some matters need attention , such as shaft centerline circle and axis vertical degree, bearing properly installed or load inverted after and so on, the following is skill method introduced.

SKF bearing and shaft with general for transition cooperate, a circle and the bearing of the hole with general for clearance fit. Two-way bearing the axis of the focuser drawtube circle should be fixed on the shaft, in order to prevent the relative to the rotation axis. Bearing installation method, usually is the axis rotation in the majority, so the inner circle of shaft for win with coordination, bearing outer ring and bearing the room with clearance fit .

 
SKF import bearings installated,  in the first dial indicators will be fixed on box shell , the head of the table to touch the import bearing shaft rotation circle groove above import bearings, edge on eye turning dial indicators pointer, if the pointer partial place, explain shaft centerline not vertical shaft and circle. If box shell hole is deeply,  also can use longer dial indicators head inspect. This is a very good inspection shaft circle and the method of vertical shaft centerline degree. SKF bearing with the installation, not only import bearing didn't work properly, and the cooperation will face severely wear. Because circle and shaft the difference is not very obvious, assembly should take more care  , can't appear upside down. Install  correctly  is the seat ring can automatically adapt to its roller rolling, ensure roller and roll in circle way. In addition, bearing a circle and import bearing hole between should be left 0.2-0.5 mm of clearance to compensate parts processing, installation is accurate errors when running import bearings in rings center migration, the clearance can ensure that its automatic adjustment, avoid touch friction, make its normal operation. Otherwise, will cause severe damage import bearings.
