Lovejoy 68514476958 Flexible Bellows Clamp 1/4 in Bore

Product Description

The LOVEJOY 68514476958 is a flexible bellows clamp-style shaft coupling designed for precision motion control and power transmission applications. The coupling features an aluminum hub paired with a stainless steel bellows element, combining lightweight construction with corrosion resistance and torsional flexibility. It accepts a minimum bore diameter of 1/4 inch, measures 1.614 inches in overall length, and has an outside diameter of 1.28 inches. Rated at 40 inch-pounds of torque, this coupling is suited for servo, stepper, and encoder shaft connections where angular and parallel misalignment must be accommodated without sacrificing positional accuracy.

This bellows clamp coupling is used in light industrial and automation environments, including CNC machinery, robotics, instrumentation, and drive systems requiring a zero-backlash connection. The clamp-style hub allows secure shaft engagement without set screws that can damage shaft surfaces. It is part of the BWC series, size code BWC41, and is typically installed by mechanical technicians, automation integrators, and maintenance professionals working on motion control equipment.

Key Features

• Clamp-style hub design secures to shaft without damaging the shaft surface
• Stainless steel bellows element accommodates angular and parallel misalignment
• Aluminum hub construction reduces rotational mass while maintaining strength
• Rated at 40 inch-pounds of torque for light-duty power transmission
• Compact profile at 1.614 inches OAL and 1.28 inches OD for tight installation envelopes
• Part of the BWC series, size code BWC41, for consistent cross-referencing

Compatibility

Designed as an OEM-style replacement or direct-fit coupling for motion control shafts with a 1/4 inch bore diameter within the LOVEJOY BWC series bellows clamp coupling line.

Installation Notes

Installation is performed by mechanical technicians or automation integrators. Ensure all equipment is de-energized and shafts are stationary before installing or removing the coupling. Clamp-style hubs require proper tightening of the clamping screws to the fastener manufacturer specifications using calibrated tooling — do not overtighten, as this can deform the hub bore. Verify shaft alignment within the coupling's rated misalignment tolerance before applying load.
