Atlas Copco M420DT Coupling

Atlas Copco M420DT Coupling is a genuine Atlas Copco two-ended drive coupling configured for the M42ODT interface on both sides, with part numbers commonly listed as 0582104200 in parts catalogs. The M42ODT two-end design indicates two mating hubs designed to couple two shafts in Atlas Copco equipment, enabling reliable torque transmission and precise alignment within oil-injected screw compressor drives. Typical applications include power transmission connections within Atlas Copco screw compressor assemblies and other drive configurations that use the M42ODT coupling interface. Catalog listings describe this component as a COUPLING M42ODT BOTH ENDS, highlighting its dual-ended configuration and its role as a direct-fit replacement part for compatible Atlas Copco installations. Sold by authorized distributors as a new, authentic replacement, the M420DT is intended to restore original performance and service life where the M42ODT coupling profile is required. To ensure proper fit, verify that both mating shafts conform to the M42ODT standard and that the mounting interfaces match your assembly, so that alignment, balance, and load paths are preserved during operation.
