Rexnord G2DBZB50 Disc Coupling

Rexnord G2DBZB50 Disc Coupling is a Thomas-brand DBZ-series coupling, size 50, designed for general‑purpose power transmission in industrial drives. The DBZ family uses two hubs inverted inside a round Tomaloy disc pack and is offered in DBZ, DBZ-A, and DBZ-B configurations, enabling compatibility with a range of hub assemblies. For size 50, the standard disc pack features a 4-bolt pattern with 0.15 in bolt holes and an inner disc diameter of 1.08 in, while the envelope measures about 6.00 in tall by 9.00 in long by 3.00 in wide, with a net weight around 0.05 lb. The disc pack material is Tomaloy and the disc pack profile is round. This coupling is intended to transfer torque between shafts with slight misalignment in demanding industrial setups. Common applications include pumps, fans, blowers, conveyors, and other machinery where a compact, flexible connection is beneficial, with DBZ variants available to suit different hub configurations.
