The professional ball bearing of major groove is turned doubly and isodiametric and ball type round and supported / crossed singly

The ball bearing of major groove has a representative antifriction bearing most, have wide use range. Suitable for the operation of the even extremely high rotational speed of the high rotational speed, and very durable, do not need to safeguard frequently. The coefficient of friction of this kind of bearing is small, the terminal rotational speed is high, simple in construction, make low cost, it is apt to reach the great to make precision. Dimensional range and form change variously, apply to trades such as accurate instrument, electrical machinery, car, motorcycle and general machinery with low noise,etc., use the most extensive kind of bearing in the mechanical industry. Mainly bear radial load, can also bear a certain amount of axial load.

Choose and increase as compared to axial bearing capacity at the time of the great radial backlash, the contact angle is zero while bearing pure radial force. When there is function of axial force, the contact angle is greater than zero. Generally adopt and ram the wave shape retainer, the car makes entity retainer, adopts nylon shelf too sometimes.

The ball bearing of major groove is installed after on the axle, within the range of axial backlash of the bearing, the axial displacement of the controllable axle or outer cover, two directions, so can be positioning axially bidirectionally. In addition the bearing have certain the intersection of cente adjusting and ability also, as 2 ‘ when the 10 ‘ of inclined relative to exterior shell holing, can still work normally, but there is a certain influence on bearing life-span. Ball bearing retainers of major groove are mostly that the steel plates ram the wave shape retainer, the large-scale bearing adopt the car to make metal entity retainer more.

The ball bearing of major groove is the most frequently used antifriction bearing. It is simple in construction, easy to use. Mainly used for bearing the radial load, but when increasing the radial backlash of bearing, have characteristic that certain angles are exposed to the ball bearing, can bear the foot-path, axial union load. When the great of rotational speed and it is unsuitable to adopt the thrust ball bearing, can also be used for bearing the pure axial load. Compared with other type of bearing that the ball bearing specification of major groove is the same in size, the coefficient of friction of this kind of bearing is small, the terminal rotational speed is high. But not shock-resistant, not suitable for bearing the heavy load.

The ball bearing of major groove is installed after on the axle, within the range of axial backlash of the bearing, the axial displacement of the controllable axle or outer cover, two directions, so can be positioning axially bidirectionally. In addition the bearing have certain the intersection of cente adjusting and ability also, as 2 ‘ when the 10 ‘ of inclined relative to exterior shell holing, can still work normally, but there is a certain influence on bearing life-span. Ball bearing retainers of major groove are mostly that the steel plates ram the wave shape retainer, the large-scale bearing adopt the car to make metal entity retainer more.
