UC type pillow block bearing is grease-sealed deep-groove ball bearing with an outer ring that has a spherical outer diameter surface fitted with an oil supply mechanism, as well as a wide inner ring that has cylindrical holes with set screws included. And the UC-type is an insert bearing with a locking device. There are usually two locking devices on the bearing with an angle of 120°. When mounted on a shaft, it is mounted on the shaft by a locking device and has a good fixing effect, but the bearing can only be used in low vibration environments.

The UC type pillow block bearing divided into three parts, UC200 series (light series), UC300 series (heavy series), and deformation products UB (SB) 200 series. If the environment is small, the UC200 series is generally selected, otherwise the UC300 series is used. UC insert ball bearings are designed for simplified mounting on shafts or in housings. They are designed for high radial and low axial forces. Their design allows them to compensate for misalignments and deflections of the shaft.

Bearing inserts of the UC200 series have an extended inner ring with grub screws for fixing the inner ring on a shaft. In comparison to the series UC300, they have smaller dimensions with the same inner diameter and a considerably lower weight.

Application

UC type pillow block bearings are relatively common and are widely used in various manufacturing industries such as textile, conveyor, foods, printing industries.
