Often use IKO bearing friends all know, rolling bearing the stand or fall of installation or not, will affect the accuracy of the life and the bearing, performance. Therefore, please study fully bearing installation, which contains the following items, please follow the steps bearing installed.

(1), cleaning bearing and related parts
To have the bearing grease lubrication and bilateral with oil seal or dust cover, the sealing ring bearings without cleaning before installation.

(2), check the relevant part size and finishing

(3), installation method

The installation of the bearing should be based on the bearing structure, size and IKO bearing parts with the nature and decide, pressure should be added to a tight fit directly to the ring width, and shall not through transfer roller pressure, rolling bearing installed generally USES the following methods:

A. the pressure with
Bearing inner circle is a tight fit axis to make, outer ring and housing is a loose with holes, usable press will be pressed on the shaft bearing first, and then will shaft bearing load bearing together together with the hole, and when pressed in bearing inner circle on the surface, a soft metal mat material of assembly casing (copper or mild steel), assembling the inner diameter of the casing shall be slightly larger than the shaft neck diameter, outer diameter circle of inner diameter than the bearing should be raised edge slightly small, lest the pressure in keep on the shelf. The rolling bearing outer ring and a tight fit bearing hole, inner circle is a loose fit for shaft, can be pressed into the housing first bearing hole, and at this time of the casing pipe diameter assembly should be slightly smaller than the diameter of a hole. If IKO bearing collar and shaft and a hole is a tight fit, install indoor circle and outer ring will also pressed into the shaft and a hole, the structure of the sleeve assembly should be can at the same time and tight inner ring and outer ring bearings of end.

B. heating with
Through the heating of bearing or bearing, using thermal expansion will be a tight fit for loose change with installation method. Is a kind of common and energy installation method. This method is suitable for the interference of the large quantities of IKO bearing installed, before hot charging bearing or separable bearing rings into the fuel tank even heating 80-100 ℃, and then removed from oil to the axes with as soon as possible, to prevent after cooling inner circle and the axial end shoulder joint not tight, bearing after cooling can again axial tighten. The rolling bearing outer ring and light made of metal tight fit the bearing, the heating of the bearing hot charging method, can avoid face with by scratches. With the fuel tank heating bearing, in a certain distance away from the tank bottom should have a place WangShan, or use hooks hanging bearing, bearing can't put on the tank bottom, in case the heavy impurity into bearings inside or not even heating, in the tank must have a thermometer, strictly control the oil temperature must not exceed 100 ℃, in order to prevent the occurrence of tempering effect, make the hardness of collar is reduced.

C. cone hole bearing installed
Cone hole can be directly into a bearing the design of the shaft neck, or loading and unloading of tight set back the cone of, with reasonable degree of the available IKO bearing radial clearance reduction is to measure, therefore, before the installation, should measure rolling bearing radial clearance, the installation process often should measure clearance to achieve need clearance reduction is so far, when installation, generally USES the lock nut installation, also can use heating installation method.

D. thrust bearing installation
Thrust bearing of the thorough and shaft with general for transition cooperate, a circle and the bearing of the hole with general for clearance fit, so the IKO bearing is easy to install, two-way thrust bearing the axis of the focuser drawtube springs in shaft shall be fixed, 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, rolling bearing outer ring and bearing the room with clearance fit for.
