Rexnord 586744 301.DBZ.CPLG ES Thomas Disc Coupling complete unit. Size 301, DBZ type, expansion spacer design. All-metal flexible disc coupling transmits torque through laminated stainless steel disc packs while accommodating misalignment. Suitable for industrial power transmission applications requiring high torsional stiffness and zero backlash.

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.
