Lovejoy 68514476957 Flexible Bellows Clamp 5/16 in Bore

Product Description

The LOVEJOY 68514476957 is a flexible bellows clamp-style shaft coupling designed to transmit torque between two shafts while accommodating minor misalignment. It features an aluminum hub paired with a stainless steel bellows element, combining lightweight construction with corrosion resistance. The coupling accepts a minimum bore diameter of 5/16 inches and has an outside diameter of 1.28 inches with an overall length of 1.614 inches. Rated at 40 in/lb of torque, it is part of the BWC series and is suited for drive train assemblies in HVAC, industrial, and mechanical equipment applications. Installation is typically performed by mechanical technicians or millwrights during new builds or scheduled maintenance.

This coupling is used in applications requiring a compact, low-backlash connection between motor shafts and driven components. The bellows design allows for angular, parallel, and axial misalignment compensation without sacrificing torque transmission. Its small form factor and clamp-style attachment make it a practical choice for tight equipment bays or inline shaft arrangements in light-duty mechanical and HVAC drive systems.

Key Features

• Clamp-style attachment for secure shaft retention without set screws cutting into shaft surface
• Stainless steel bellows element provides flexibility and corrosion resistance
• Aluminum hub reduces rotating mass for responsive drive response
• Rated torque of 40 in/lb suitable for light-duty mechanical drive applications
• Compact overall length of 1.614 inches fits space-constrained installations
• Part of the BWC series with coupling size code BWC41 for straightforward reordering

Compatibility

Designed as an OEM-style replacement or new-installation coupling for light-duty mechanical and HVAC drive shaft assemblies requiring a minimum bore diameter of 5/16 inches and a clamp-style bellows coupling in the BWC series.

Installation Notes

Installation should be performed by a qualified mechanical technician or millwright. Disconnect and lock out all power to the equipment before removing or installing any shaft coupling. Ensure shaft surfaces are clean and free of burrs before inserting into the clamp bore. Torque the clamp fasteners per the equipment manufacturer specifications and verify shaft alignment before returning the system to service.
