Rexnord DC00454 263.DBZC Thomas Disc Coupling Component with HRB/HRB bores and 5.50 length. This disc coupling component is designed for use in Thomas disc couplings, providing flexible torque transmission with stainless steel disc packs.

Rexnord Thomas DBZ disc couplings are legacy general purpose high-speed, high-torque couplings. Typical applications include mixers, compressors, agitators, blowers & fans, centrifugal pumps, and conveyors. DBZ couplings are available in three configurations to maximize application flexibility:

• DBZ: Both hubs are inverted inside the disc pack for minimal shaft-to-shaft spacing
• DBZ-A: One hub is extended to accommodate taper bores and larger shaft gaps
• DBZ-B: Both hubs are extended for maximum shaft-to-shaft spacing

DBZ couplings are available in 13 sizes ranging from size 50 through 451, and are designed to accommodate maximum continuous torque loads up to 43,400 (lb-in) and shaft diameters up to 4.63 inches.
