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 spacingDBZ-A: One hub is extended to accommodate taper bores and larger shaft gapsDBZ-B: Both hubs are extended for maximum shaft-to-shaft spacingDBZ 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.
