Rexnord G4DBZ101 101.DBZ Thomas Disc Coupling complete unit, 101 size, DBZ type, close bore (CB) configuration, standard duty (SD) design. All-metal laminated stainless-steel disc pack transmits torque while accommodating angular, parallel, and axial misalignment without lubrication. Suitable for pumps, compressors, and industrial drives requiring zero-backlash torque transmission.

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.
