The ball bearing of major groove is the most ordinary kind of type in antifriction bearing. The ball bearing of major groove of the basic model is by an outer lane, an inner circle, a series of steel balls and a series of retainers are constructed. The ball bearing type of major groove has two kinds of unilines and biserials, ball structure of major groove is also divided into two kinds of structure of sealing and open system, the open system refers to the bearing without containment structure, the major groove ball of the sealed is divided into and sealed and defended oil-tight dustproofly. The dustproof Sealing Cover material is rammed for the steel plate, only get up to enter the ball track of bearing to the simple prevention dust. It defends oil types to be contact-type oil seal, can valid to prevent the intersection of bearing and inner grease from overflow.

Uniline’s major groove ball bearing type coaxiality is 6, the two-bank ball bearing coaxiality of major groove is 4. It is simple in construction, easy to use, it is most general to produce, employ the most extensive kind of bearing.

2 operating principles

The major groove ball bearing mainly bears the radial load, can also bear radial load and axial load at the same time. When it only bears the radial load, the contact angle is zero. When ball bearing has a greater radial backlash in the major groove, have characteristic that angles are exposed to the bearing, can bear the greater axial load, the coefficient of friction of the ball bearing of major groove is very small, the terminal rotational speed is very high too.

Bearing structure

The ball bearing of major groove is simple in construction, easy to reach higher manufacture precision compared with other types, so is easy to produce in enormous quantities as the series, the manufacturing cost is lower, it is extremely general to use. The ball bearing of major groove is besides basic model, and various structure of modifying, for instance: The ball bearing of major groove with dust cap, the ball bearing of major groove with rubber grommet, there is ball bearing of major groove of the locking recess, there is a ball bearing of major groove of the large load capacity which holds the ball gap, two-bank ball bearing of major groove.
