Regal Beloit B350X1-1 Bearing

Regal Beloit’s Hub City FC350 X 1-15/16 flange block bearing centers on an insert bearing using the B350 insert, designed for a 1-15/16 in bore. The four-bolt round flange cartridge is built with a cast‑iron housing and accepts four mounting holes, arranged with a bolt spacing of 3.8 in (95.5 mm). The insert’s bore is 1.938 in (49.225 mm), and the cartridge includes a 4.5 in (114.3 mm) pilot diameter with a 0.625 in (15.875 mm) pilot depth, enabling precise alignment within machinery frames. The unit uses a set screw mounting method and provides a through-bore length of 1.772 in (45 mm), making it suitable for applications requiring a compact, reliable insert bearing in conveyors, material handling, and similar industrial equipment. Manufactured by Regal Beloit under the HUB CITY brand, the FC350 X 1-15/16 configuration is a standard, interchangeable solution for robust flange-block bearing needs.
