Rexnord DA00111 226.DBZA Thomas Disc Coupling Component with 1.88" bore on both ends and 2.53" length. This disc coupling part is designed for use with Thomas disc couplings, providing reliable torque transmission and misalignment accommodation in industrial power transmission applications.

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.
