Product Description

Angular Contact Ball Bearing with Split Inner Race QJ-303

Angular contact ball bearings are particularly suitable for carrying combined (axial and radial) loads. Sometimes, they also can carry pure axial load and operate in higher speed. Under radial load, axial component force will be produced which must be counteracted. So the bearings are normally adjust against a second bearing. Since these bearing have a contact angle, they can subtain significant axial loads in one direction together with radial loads. Because of their design, when a radial load is applied, an axial force component is produced; therefore, two opposed bearings or a combination of more than two must be used(DB,DF,DT)

1)Single row and combined angular contact ball bearing

The more contact angle is, the larger axial load bearing capacity is,the smaller contact surface is,themuch more convenient high speed rotary is.

Pretension is made on angular contact ball bearing to increase rididity and accuracy of bearing.

This bearing creates axial thrust load when being forced by radial load,thus it is configured(or combined) face to face or back to back.

angular contact ball bearing has the following advantages: used ultra clean steel extend service life of the bearing for 80% .special Honing control noise of bearing in in the smallest degree.Improve the dispersion of lubricant and improve its service life.The angle of angular contact ball bearing usually 15 degree,25 degree ,40 degree and 60 degree.For angular contact ball bearing70,72,718,719 series,we make C(15 degree) and AC(25 degree).The bearings mainly applied in machine tools,especially spindle,high speed motorized spindle.

2)Double row angular contact ball bearing

Double row angular contact ball bearing can be submitted radial and axial loading limit speed is quite high, it is non-separated type of bearing has high rigid can be submitted double direction of axial load,the bearing could apply with the four row cylindrical bearing together to limit the working roll to move in axial direction the double row angular contact ball bearing could apply with other bearings as a position bearing.

3)Four point contact ball bearing

Standard structure is that its inner ring is equally divided in axial direction,which is applicable to axial load or combined load,among which axial load is major composition.

Single bearing can bear double row axial load and certain extent radial load.According to different direction of axial load,ring and sphere always contact at two points of linear

Ring(race) material: chrome steel(Gcr15), stainless steel, ceramics. Usually we often use chrome steel(Gcr15).

Cage materials are mostly adopted reinforced glass-fibre(nylon) and stamped brass or machined brass, the suffix is P, PH, Y, M.
