The classification of the bearing – ball bearing of the major groove – cente adjusting roller bearing – exterior sphere ball bearing:

1.Major groove ball

The major groove ball bearing imports the bearing and is used mainly for accepting the pure radial load, can also accept radial load and axial load at the same time.

2.Subcategory of rolling of cente adjusting

The roller bearing of cente adjusting is that the inner cycle sum ball track with two ball tracks is during the outer lane in the sphere, bearing that is assembled drum-shaped roller.

3.Needle rollers

The needle bearing contains the detailed and long roller roller length is 3~10 times more diametral, it is compact radially that the diameter is not generally greater than 5mm, when the size and loaded ability of its internal diameter are the same as other types bearing, the external diameter is minimum, are especially suitable for the res. supporting structure of the radial device size. The needle bearing can choose the bearing or needle roller without inner circle and insist on a assembly on the basis of the location of use. Bearing knowledge

4.Cente adjusting ball

The ball bearing of cente adjusting: The inner cycle sum ball tracks of two ball tracks are between the outer lanes in the sphere, assemble the bearing with drum-shaped roller.


There is flange of flange on the flange bearing foreign steamer. Can simplify the structure of the host computer, narrow the host computer size, makes the bearing easier to position in characteristic

6.Exterior spheres

The exterior sphere ball bearing is actually a kind of variant of the ball bearing of major groove, the characteristic is that the external diameter appearance of an outer lane is a sphere, can be worthy of entering and acting as the bearing in the corresponding concave sphere of pedestal.
