Knowledge of UK208 bearing insert ball bearing

The outer spherical ball uk208 bearing is actually a variant of the deep groove ball bearing. The outer spherical bearing is mainly used to bear the combined radial and axial load.Mainly based on the radial load, and it is generally not suitable to bear the axial load alone.
Insert UK208 bearing are preferably used in simple equipment and components.
Such as agricultural machinery, transport systems or construction machinery.

The size of axial clearance of UK208 bearing has a great relationship.That whether the bearing can work normally. When the axial clearance is too small, the temperature rise is high; when the axial clearance is large, the bearing is easily damaged.
Therefore, special attention should be paid to adjusting the axial clearance.During installation and operation. If necessary, pre-interference installation can be performed to increase the rigidity of the bearing.

Outer spherical ball bearings can be divided into three categories according to the method of cooperation with the shaft:

1. insert ball bearing with top wire.

Its code is: UC200 series (light series), UC300 series (heavy load)

2.the tapered outer spherical ball bearing.Its code is: UK200 series, UK300 series.

This type of outer spherical ball bearing has a taper bore with an inner diameter of 1:12.

Usually,like UK208 bearing need to be used with adapter sleeve.

3.Outer spherical ball bearing with eccentric sleeve Its code is: UEL200 series, UEL300 series, SA200 series.

Widely used in textile machinery, ceramic machinery and other industries.
The spherical bearing with seat is divided into bearing center and bearing seat, which is called bearing center plus bearing seat in the name.
Because of its strong interchangeability, the bearing center can be freely assembled in the bearing housing of the same specification and different shapes.
