Full installation with needle bearings NSK, usually use auxiliary sleeve. Auxiliary roller, auxiliary sleeve of outer diameter than axis should be small diameter 0. 1-0. 3 mm. Installation, bearing outer ring inside surface first coated with grease, close inside surface stick put needle (into the last one needle should be gaps), then instead of shaft neck or bearing inner circle of auxiliary roller or auxiliary sleeve push the outer ring hole, and its end at the installation shaft installed on the end or on the shaft bearing inner ring end, then use press or hammer pressure on. At this time, the auxiliary roller or auxiliary sleeve and hold needle don't make needle off, shaft neck with his own chamfering will needle lift, with needle bearings in the shaft neck to move slowly, auxiliary roller or auxiliary sleeve will slowly quit, until loaded to work position so far.

IKO needle bearing can also this installation, is auxiliary sleeve with a thin layer of oil diameter, set into the bearings outer ring, make the auxiliary sleeve and bearing outer ring constitute a circular hole, and then annular aperture to mount the needle. Loaded after needle, work with auxiliary shaft will launch the sleeve can.

For no inner ring or the needle TIMKEN bearing, when installation, can mix shaft or shell hole surface rolling with a thin layer of grease, and put the needle in turn to install to parts of the grease. Stick put last one needle should be gaps, the size of the gap in the needle bearing of circles to 0. 5 mm is advisable. Don't put the last one needle hard crowded pack, or less in a root needle, because hard crowded outfit, the bearing can be jammed can't spin; Little outfit, the gap is too big, easy cause bearing operation needle happen twist and broken.

 
Here is particularly pointed out that, for only the stamping outermost needle KOYO bearing, due to the outer wall is thin, had better not use hammer beat installation, use should be pressed into the press. Because hammer knock, uneven pressure, easy to make needle bearing outer produce local deformation.
