The UCT Take Up Unit has narrow machined grooves either side to allow movement on suitably machined rails, and a tapped hole in the base to attach a threaded bar to facilitate adjustment. They are typically used for conveyor roller tension system, plug valves, check valves, traps, welding stations, row welding machines, plasma welding machines, impactors and etc.

Outer spherical bearings are preferred for occasions requiring simple equipment and parts, such as agricultural machinery, transportation systems or construction machinery.

Outer spherical ball bearing is actually a variant of deep groove ball bearing. Its characteristic is that its outer ring outer diameter surface is spherical, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of centering.

This kind of bearing has sealing rings on both sides to prevent the intrusion of dirt. The appropriate amount of lubricant has been filled at the factory and does not need to be cleaned before installation. , No need to add lubricant, when the jack screw on the protruding end of the bearing inner ring is tightened on the shaft. The allowable axial load shall not exceed 20% of the rated dynamic load.

The performance of the outer spherical ball bearing with eccentric sleeve and the outer spherical bearing with top thread are basically the same, except that the top thread is not on the inner ring, but on the eccentric sleeve. The inner hole of the tapered outer spherical ball bearing is a tapered hole with a taper of 1:12, which can be directly installed on a tapered shaft or on an optical shaft without a shoulder by means of a tightening bushing, and the bearing clearance can be fine-tuned.

It is mainly used to bear the combined radial and axial load based on the radial load. Generally, it is not suitable to bear the axial load alone. This kind of bearing can be installed with an inner ring (with a full set of rollers and retainers) and an outer ring separately. This kind of bearing does not allow the shaft to be inclined relative to the housing, and additional axial force will be generated under the radial load. The size of the axial clearance of this kind of bearing has a great influence on whether the bearing can work normally. When the axial clearance is too small, the temperature rise is higher; when the axial clearance is large, the bearing is easy to be damaged. Therefore, pay special attention to adjusting the axial clearance of the bearing during installation and operation, and pre-interference installation can be used if necessary to increase the rigidity of the bearing.
