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.
