Remove the NSK bearings, should use the appropriate pulling force implement will pull bearing, don't use hammer, the iron stick or Chong top tool a knock on people.

When installation should be based on the bearing structure bearing and its size and the cooperation among components nature decided to install method. The general principle is: installation shall be directly added to the pressure of a tight fit a circle on the surface, not through the rolling body indirectly transfer installation pressure. Installation bearing general take the following methods:

1. The pressure into the installation. FAG bearing a circle in the axis of a tight fit, outside a circle with a hole with a loose, usable press will be pressed into shaft bearing first neck, and again the shaft bearing load bearing together with the holes. If a circle and the bearing a hole for a tight fit, can be a sleeve bearing through the first seat hole in the press, the sleeve wall thickness and the thickness of a circle is, outside diameter is slightly less than a hole diameter. Bitter bearings and shaft neck, a hole is a tight fit, installation should be will bearing pressure people shaft neck and a hole, power transmission sleeve for double, can at the same time pressure inside, outside a circle ends, and the pressure to end a circle inside and outside. Note can't let roller bearing.

2. Heating installation. This method using heat bilges cold shrink of truth, through the heating of bearing or bearing hole, become a tight fit for loose cooperate, with convenient installation. The method is: will bearing to put oil heating to 80% lOOT:, hot and quickly set out bearing in shaft neck. If a circle and the bearing a hole tight to cooperate, can a hole of metal heat around. When heated to prevent the bearing by high temperature and annealing, should bearing mount in oil, bearing and the bottom of the container to avoid direct contact heat parts. Must use thermometer monitoring the oil temperature; The oil temperature must be strictly controlled, shall not be more than lO0 ~ C, in order to prevent to produce tempering effect, make bearing hardness decline.

3. Cone hole bearing installed. The bearing can be directly in SKF suit has advantages of shaft neck. With the reasonable degree of the available bearing axial gap reduction is to measure. Before installation, to measure the bearing radial clearance, during the installation process to continuously measuring clearance, when the need to stop gap value installation. Cone hole bearing with twist into general lock nut method for installation, also can use heating method with installation.

4. The installation of thrust bearing. The bearings and shaft neck with general for transition, a circle and the bearing of the hole with general for clearance fit, installation is easy. Bearing and the movement of the axis relationship, to move a shaft for the majority, so in the hole and shaft for full cooperation, rim and a hole for clearance fit.
