Lovejoy 68514476983 Flexible Bellows Clamp 3/4 in Bore

Product Description

The LOVEJOY 68514476983 is a flexible bellows clamp-style shaft coupling designed to transmit torque between two shafts while accommodating angular, parallel, and axial misalignment. The coupling features an aluminum hub body paired with a stainless steel bellows element, combining lightweight construction with corrosion resistance. It is rated to 159 inch-pounds of torque and accepts a minimum bore diameter of 3/4 inch, making it a compact solution for motion control, pump drive, and servo applications. Maintenance technicians and mechanical system integrators working on precision drive trains will find this coupling suitable for demanding environments where flex and durability are both required.

The LOVEJOY 68514476983 belongs to the BWC Series bellows clamp coupling line, sized to coupling size code BWLC63. It is suited for use in industrial machinery, light-duty servo systems, pump and compressor drive connections, and similar rotating equipment where controlled flexibility and positive torque transfer are critical. The clamp-style hub attachment allows secure shaft retention without the need for set screws alone, providing reliable grip on 3/4 inch shafts across a range of rotational speeds and load conditions.

Key Features

• Clamp-style hub design for secure shaft retention on 3/4 inch bore shafts
• Stainless steel bellows element provides flexibility and corrosion resistance
• Aluminum hub body reduces rotating mass while maintaining structural integrity
• Rated torque of 159 inch-pounds for demanding drive applications
• Compact envelope: 1.77 inches outside diameter and 2.48 inches overall length
• BWC Series construction for consistent dimensional compatibility within the LOVEJOY bellows coupling line

Compatibility

Designed as a replacement or new-installation bellows clamp coupling within the LOVEJOY BWC Series, coupling size code BWLC63, for rotating shaft applications requiring a 3/4 inch minimum bore diameter.

Installation Notes

Installation should be performed by a qualified mechanical technician. Disconnect and lock out all power to the drive system before handling any shaft coupling. Ensure both shaft ends are clean, free of burrs, and within the specified bore tolerance before seating the hubs. Do not exceed the rated torque value when applying clamping hardware, and verify shaft alignment to manufacturer specifications before returning the system to service.
