1. The positioning of the inner ring bearings

Rui fine mechanical and electrical provide extended industrial bearings of all-round solutions installation bearing inner circle, is general by shaft shoulder in a fixed bearing position, and on the other side will use nuts, stop moving gaskets or spring archives circle and fixed. Shaft shoulder and axial fixed parts and bearing inner circle is the size of the contact part, can press bearing listed all kinds of bearing size form installation dimensions for sure.

(1) nut positioning

In high speed bearings, bear larger axial load, nuts and bearing inner circle of end to contact with the axis of rotation vertical lines. Otherwise even tighten the nut will also destroy the installation position of bearing and bearing the normal work of the state, low bearing rotation precision and service life. Especially in the hole and the shaft bearing with for loose fit, the more need to strictly control.

In order to prevent the nut in rotating occurred in the process the loose import bearings brand code conversion table, the need to take the appropriate measures to prevent loose technology. Use nuts and a check dynamic gasket positioning, will stop moving in key into the shaft washer tooth of the keyway inside, then the outer ring of the tooth in a turn into the nut of the incision.

(2) spring archives circle positioning

Bearing axial load is not big, speed is not high, the shaft is shorter and the shaft neck processed into threads are difficult conditions, can be used for rectangular cross-section of elastic archives circle positioning. The method of handling is very convenient, accounts for a small position, make simple.

(3) thrust washers positioning

The neck is shorter, CSK type, CKF type, CKA type, CKB type, CKD type overrunning clutch bearings application and characteristics shaft neck processed into threads are difficult, bearing speed higher axial load, much bigger, can use gasket orientation, which in the end shaft washer with more than two screws positioning, with stop moving gaskets or wire twist death, prevent loose.

(4) tight set of positioning

Speed is not high, bear radial load and not smooth the axial load of spherical roller bearing, can be in the axis with tapered tight set set of installation. Tight set to move the nuts and washers positioning. Use nut lock for the friction set tightly will bearing orientation.

(5) in the hole of a taper bearing orientation

The design of the bearing is installed on the taper shaft, all kinds of precision combination needle bearing type swap table need to make the axial load for top tight axis and bearing, so when installation should pay attention to in the hole taper the direction. Such as bearing is located in the shaft and the shaft allows processed into thread, can use directly nut positioning.

Bearing is not installed in the shaft, and shaft don't allow processed into threads. In this case, can use two combined thread ring card slots in the shaft, reoccupy nut positioning bearing.

(6) special position

Some special cases, the axis of a shoulder and fillet in this directory sizes can not be listed in the installation size determine, can use transition gasket as axial bearing.

2. Bearing outer ring positioning

Needle bearing the classification and various components, mark in outer shell method in holes in the installation, the inside of the hole on the outside shell generally have accounted for the position of the fixed bearing shoulder, another side cover, thread with ring and hole with elastic archives circle positioning, etc.

(1) cover positioning

Positioning used for all types of to heart bearings and angular contact bearings, in high speed bearings, axial load under heavy use. Cover with bolt positioning pressure bearing outer ring, cover a labyrinth seal device.

(2) thread ring positioning

Speed is higher, axial load is bigger, is not suitable for use under the condition of the cover positioning water pump bearing \ available thread ring positioning to heart bearings and thrust bearing, at this point, used to adjust the bearing axial gap.

（3) elastic archives circle positioning

Positioning method of axial position of small, install and disassemble manufacturing of simple, applicable to inherit the smaller axial load place. In the bearings and spring and a link between adjustment, easy to adjust the axial position.

(4) bearing outer ring on the move with the slot deep groove ball bearings, can be used to stop ring positioning.
Shell hole because of the conditions of the limit can't stop moving files processing shoulder, or parts must be cut outline size, choose this type.
