Lovejoy 68514476951 Flexible Bellows Clamp 1/2 in Bore

Product Description

The LOVEJOY 68514476951 is a flexible bellows clamp-style shaft coupling designed for motion control and power transmission applications. It features an aluminum hub paired with a stainless steel bellows element, combining lightweight construction with corrosion resistance and torsional flexibility. The coupling accepts a minimum bore diameter of 1/2 inch, measures 1.280 inches in outside diameter, and has an overall length of 1.614 inches. It is rated at 40 inch-pounds of torque. Part of the BWC series, this compact coupling is installed by mechanical and industrial maintenance technicians working on precision drive systems.

This coupling suits applications where shaft misalignment compensation and reliable torque transmission are required in a small form factor. The clamp-style hub attachment provides secure shaft retention without requiring adhesives or keyways. Typical installations include small motor drives, encoder connections, stepper motor assemblies, and light-duty power transmission setups in both industrial and commercial environments. The stainless steel bellows element accommodates angular and axial misalignment while maintaining consistent torque transfer.

Installation Notes

Installation is performed by qualified mechanical technicians or industrial maintenance personnel. De-energize and lock out all connected drive equipment before installing or removing the coupling. Ensure shaft surfaces are clean and free of burrs before seating the hub, and verify bore alignment before tightening the clamp fasteners. Follow applicable ANSI and equipment manufacturer guidelines for shaft coupling installation procedures.
