DYZV Angular contact ball bearings

DYZV Angular contact ball bearing have high limit rotational speed, they can carry radial load and axial

load simultaneously, they cal also withstand purely radial load. The axial load carrying capacity depends

on the magnitude of contact angle and increases with increasing contact angle.

Structures

1. Separable angular contact ball bearings

The inner ring and outer ring of this type of bearings cannot be separated and comprises

following structures:

Contact angle *=15กใ, counter bore on outer ring, 7000C type

 Contact angle *=25กใ, counter bore on outer ring, 7000AC type

 Contact angle *=40กใ, counter bore on outer ring, 7000B type

2. Four-point contact ball bearings

This type of bearings is separable bearings. Whereof, QJ000 type has two-piece inner ring and QJF000 type has two-piece outer ring. Their contact angles are same as 35กใ. When received no load or pure radial load, the steel balls of the ball bearing contact with the four points of the rings. Besides the steel balls perform a two-point contact with the ring when it is received a pure axial load. In addition, besides the axial load from both directions, this kind of bearing can take torque-load as well.

3. Double row angular contact ball bearings

This kind of bearings can accommodate radial loads as well as axial loads acting in both directions; they can also take torque-load. They can restrain the axial displacement from both directions of the shaft or housing; the contact angle is 30กใ (or 40กใ).
