The UC212 bearing is a compact unit that integrates a rolling bearing with a housing. Its most distinctive feature is that the outer diameter surface of the bearing's outer ring is spherical. This allows it to engage with the concave spherical inner bore of the bearing housing, thereby providing a self-aligning capability. This functionality compensates for misalignment caused by installation inaccuracies or shaft deflection
.
This model typically employs a set screw locking design. The bearing is generally equipped with two set screws, often positioned at an included angle of 120 degrees, which are used to fasten the bearing directly onto the shaft for secure fixation
.
The bearing is usually supplied pre-lubricated with grease and equipped with seals, such as non-contact labyrinth seals or combination seals. This effective sealing system helps prevent the ingress of contaminants, contributing to maintenance-free or low-maintenance operation
.
It is primarily designed to withstand combined radial and axial loads, with the radial load being the dominant component
