The inner or outer needle INA bearings when installing the first axis or shell holes scroll coated with a thin layer of grease and turn the needle close to the grease on the installation position. Paste to put the last one needle should be left the size of the gap, the gap in the circumference of the needle bearing. 5mm appropriate. Do not squeeze the last one needle loaded into, roles fitted to a needle, because the hard squeeze mounted, the bearings will be stuck can not be rotated; less loaded, the gap is too large, FAG bearings authorized dealer could easily lead to when the needle bearing operation Wiggler and broken.
Special Drawn Cup CARB bearing, the outer walls were very thin, it is best not to hand a hammer to install, you should use the press pressed into. Sweden, SKF bearings because the hand hammer, uneven pressure, easy to make the outer ring of needle roller bearings to produce local deformation. (SKF bearing)
Install the full complement needle roller bearings, NSK Bearings distributor in China are usually auxiliary sleeve. At this time, the United States TIMKEN bearings auxiliary roller or auxiliary sleeve lift up the needle does not make the needle to fall out of the journal in its own chamfering needle off with the needle bearing in the journal in slow moving auxiliary rollers or auxiliary sleeve will slowly withdraw until loaded into the working position so far. Auxiliary roller, auxiliary sleeve diameter than the shaft diameter of 0. 1-0. 3mm. Installation, the first bearing outside the inner surface coated with grease, try to be within the surface mount put the needle (into the last one needle should be left gap), then instead of a journal or bearing inner ring of the auxiliary roll or auxiliary sleeve pushed into the outer hole, and to make it face align the mounting shaft ender have been installed on the axis of the bearing inner ring face, then put pressure on the press or hand hammer.
