Rexnord 401DBZ Hub

Rexnord 401DBZ Hub is a standard rough-bore hub designed for Rexnord Thomas DBZ/DBZ-A disc couplings in size 401. Part number 816120, this steel hub features a flange outer diameter of 10.69 inches and is specified for coupling size 401. The DBZ family uses two inverted hubs to minimize shaft-to-shaft spacing, and the DBZ-A variant adds one extended hub to permit tapered boring in configurations that require it; Thomas DBZ hubs span sizes 50 through 451. As a rough-bore hub, it ships without a finished bore, ready to be machined to fit the application shaft. It is intended to be used with the Thomas disc packs to form a complete coupling assembly in industrial power transmission applications where compact spacing is beneficial, such as machinery drives and conveyors that employ Rexnord Thomas disc couplings. This hub is made of steel and is designed to pair with the corresponding DBZ discs to deliver a robust, reliable shaft connection in demanding manufacturing environments.
