Coupling 20D Mechanical Shaft Coupling ID 2.5 OD 2.1

Description:

The Coupling 20D Mechanical Shaft Coupling is used in industrial power transmission systems to connect rotating shafts and transmit torque while accommodating minor misalignment and vibration. Commonly installed in pumps, conveyors, gear reducers, compressors, mixers, and manufacturing equipment requiring reliable shaft-to-shaft power transfer. Maintenance teams and system integrators use this coupling for replacement, repair, and retrofit projects to maintain drivetrain performance and reduce equipment downtime. The coupling features an approximate 2.5-inch inside diameter and 2.1-inch outside diameter configuration. 

Applications:

The Coupling 20D Mechanical Shaft Coupling is commonly used in industrial machinery, material handling equipment, pump systems, packaging machinery, agricultural equipment, and power transmission assemblies where rotational motion and torque must be transferred between connected components. Couplings help compensate for minor shaft misalignment while reducing shock loads and vibration transmitted through the drive system.
