Angular Contact Ball Bearings 71900C Series

Insert ball bearings with set screws are available in the UC200 series, UC300 series, and their variant, the UB(SB)200 series. If the application environment is less suitable, the UC200 series is generally selected; otherwise, the UC300 series is preferred. Insert ball bearings typically have two set screws, angled 120° apart. Their characteristic is that they use the set screws to secure the shaft when mating. However, the mating environment requires minimal vibration. This type of insert ball bearing is quite common and is widely used in various manufacturing industries, including textile machinery and ceramic machinery.

These bearings are also designed to be self-aligning, easy to install, and feature a dual-structure seal, allowing them to operate in harsh environments. Bearing seats are typically cast. Commonly used seats include vertical seats (P), square seats (F), boss square seats (FS), boss round seats (FC), diamond seats (FL), annular seats (C), and slider seats (T).
HZK Hot-selling models include UC200 series, UC300 series

Insert bearing units are divided into a core and a housing. The core and housing are usually referred to together, such as the UC205 insert bearing with set screws and a housing, called the UCP205. Insert bearing units are highly interchangeable, allowing the core to be freely assembled in housings of the same specification or different shapes.
