Industrial Center Spool Coupling 6-3/4 OD 4 ID Center Spool Coupling

The Center Spool Coupling with 6-3/4 in OD by 4 in ID delivers reliable torque transmission between rotating shafts while accommodating minor misalignment in industrial power transmission systems. As a spacer/center spool for shaft coupling assemblies, it serves as the central connecting element that enables easier maintenance of pumps and motors without disturbing connected equipment, with common applications in pumps, motors, compressors, gearboxes, mixers, and conveyor drives. The coupling is a precision‑machined industrial component available in carbon steel, alloy steel, or stainless steel (manufacturer dependent), with mounting options that include flanged or hub connections. Its operating characteristics emphasize smooth torque transfer while tolerating small shaft misalignment, along with high strength, vibration reduction, wear resistance, easy installation, and long service life.
