Installation method to install bearing improper use, cause damage to the bearing. Therefore, the correct mounting bearings is a prerequisite to ensure bearings run smoothly, there is clearance fit of the bearing rings, it is recommended that the mating surfaces coated with a thin layer of anti-worming corrosive to prevent fretting corrosion between mating surfaces. Here's hope that a more comprehensive understanding of the mounting and dismounting of bearings:
1, SKF bearings dismounting skill maintenance method:
(1) unscrew bolts with a fixed housing. Will be removed from the shaft with bearings SKF bearings. Note before the split housings on the axis side. Axis should be I flange bolts loosen on the other side, so as not to damage bearings at both ends.
(2) first with a hex wrench, loosen the bearing eccentric collar locking screws, and then with a small iron bars inserted sink hole in the eccentric sleeve for the top cover, reverse the direction of rotation of the shaft beat eccentric sleeve.

2, installation techniques and considerations of bearing:
(1) the correct installation, is very important for bearings used. In the hope that we can use at a later time using the correct installation method.
(2) when installed according to their type and size, select methods such as mechanical or hydraulic, heating. Installation force imposed on the bearings, never by rolling pass from one ring to another ring, doing so may damage the Raceway. But in any case, are not directly hit ring, cage, rolling element bearings or seals.
(3) load eccentric sleeve. First eccentric eccentric on the steps of the bumpers in the bearing sleeve, direction along the axis of rotation and hand tighten. Then insert a small iron bars or resist sink hole in the eccentric sleeve. Bishop with the direction of rotation of the shaft the rhythm small iron bars. The eccentric sleeve is securely, and finally locking hex screws on the eccentric sleeve.
(4) fixed flange bolts not tightened, bearing coats bearing be able to rotate. Then bearing bolt good. Similarly packed bearing at the other end and the on the same axes, axis circles, so that automatically find the bearing itself is location.
(5) in the bearing and bearing surfaces coated lubricant, mount bearing housings. And then assembled bearing and bearing with sleeve on the shaft. Push-installed to the location you want. SKF bearing dismounting skill maintenance methods and techniques of SKF bearings bearing installation
(6) prior to installing the bearings on the shaft, you must first disconnect the pin bearing coat, smooth clean surface grinding of shaft neck at the same time, and oiled at the axle Rust prevention and lubrication (allows the bearing on the shaft there is a slight rotation).
(7) the dust on the fan clean, avoiding dust again in entered the bearings during installation;
(8) the bearing seal sticker removed, remove the latch on the axis;
(9) the residual oil in the bearing with a clean tissue or wipe with a soft cloth, and then clean your shaft;
(10), adding a little butter in the bearing, the principle is rather not much less so as not to seriously affect the speed;
(11) then cut according to the aluminum skin of the cans bearing the latch as big as the diameter cutting wafer, and digging in the middle of a cross shaft hole, it cushions in between the bearings and the latch, reduce the axial movement of the bearing and the distance in parallel. As a large gap between them, mat a few thick rows, move back and forth bearing distance below 0.5mm; SKF bearing dismounting skill maintenance methods and techniques of SKF bearings bearing installation
(12) Letter to the oil well, coupled with some butter, and finally put the fans back video card. Connected to the power supply to try, you will find
