Industrial USRB5000-111C Pillow Block Bearing

The Sealmaster USRB5000-111-C unitized spherical roller bearing comes mounted in a cast-iron two-bolt pillow block housing, delivering robust, misalignment-tolerant support for industrial shafts. This model accepts a 1-11/16 in bore (1.6875 in) and uses a 52100 bearing steel assembly with a black-oxide coated finish, built to withstand demanding, continuous-duty service. The unit features collar-mount lock and a double lip contact seal to help keep contaminants out while maintaining accurate shaft alignment in a compact, base-mounted package. The USRB5000 series is designed for precise, fixed- or gravity-fed conveyor lines, machinery requiring unitized bearings, and other industrial drive systems where reliability and extended service intervals matter. With its cast iron housing and rigid two-bolt base, it provides stable mounting and straightforward maintenance, making it a common choice for replacement in existing Sealmaster installations and compatible systems that require a two-bolt pillow block unitized spherical roller bearing.
