Lovejoy 68514477391 Flexible Bellows Clamp 1/4 in Bore

Product Description

The LOVEJOY 68514477391 is a flexible bellows clamp-style shaft coupling designed for motion control and power transmission applications. It combines an aluminum hub with a stainless steel bellows element to deliver torsional rigidity while accommodating minor shaft misalignment. With a minimum bore diameter of 1/4 inch, an outside diameter of 1.28 inches, and an overall length of 1.614 inches, this compact coupling fits tight installation envelopes. It is rated for up to 40 inch-pounds of torque. Mechanical technicians and industrial maintenance professionals install this coupling in servo, stepper motor, and precision drive train assemblies.

This coupling is suited for light-duty to medium-duty drive applications where precise torque transmission and misalignment compensation are both required. The clamp-style hub attachment provides secure shaft retention without set screws marring shaft surfaces. Typical install scenarios include encoder mounts, lead screw drives, pump shafts, and actuator assemblies in both industrial and commercial equipment. The stainless steel bellows element resists corrosion, making it appropriate for wash-down or moderate-moisture environments.

• Compact envelope: 1.28 inches OD x 1.614 inches overall length
• BWC series, size code BWC41

Compatibility

Designed as an OEM-style replacement or direct-fit coupling for 1/4 inch bore shaft applications in the LOVEJOY BWC series, size BWC41.

Installation Notes

Installation should be performed by qualified mechanical technicians with the drive system fully de-energized and locked out per applicable LOTO procedures. Clean shaft surfaces before inserting into the clamp hub and ensure shaft ends are seated to the correct depth before torquing the clamp screws. Do not exceed the rated torque capacity of the coupling when sizing the application. Consult applicable machinery safety standards for drive train service requirements.
