Zurn 073907-003B F201.25 SB Tapped Sleeve 073907003B

Description:

The Zurn 073907-003B F201.25 SB Tapped Sleeve is a gear coupling sleeve component used in industrial power transmission systems to connect and transmit torque between shafts. It is part of the Ameridrives (Zurn) gear coupling system, specifically designed for F201.25 size couplings. This sleeve features tapped holes for bolted assembly and is typically used in heavy-duty rotating equipment such as motors, pumps, compressors, and industrial drives.

Applications:

The Zurn 073907-003B tapped sleeve is used in gear coupling assemblies where high torque transmission and shaft misalignment compensation are required. It is widely applied in steel mills, power plants, conveyors, and heavy industrial machinery. Gear couplings like this consist of hubs and sleeves that mesh together to allow torque transfer while accommodating angular and parallel misalignment, improving equipment lifespan and reliability.
