Lovejoy 68514477390 Flexible Bellows Clamp 3/8 in Bore

Product Description

The LOVEJOY 68514477390 is a bellows clamp-style flexible coupling designed for shaft-to-shaft connections in mechanical drive applications. 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 3/8 inch, measures 1.28 inches in outside diameter, and has an overall length of 1.614 inches. With a rated torque of 40 inch-pounds, it suits light-duty motion control, servo, and positioning system installations. Mechanical contractors and machine builders working with small-frame motors, encoders, or pumps typically install this type of coupling.

This coupling is used in residential and light commercial mechanical systems where precise shaft alignment and vibration dampening are required. The bellows design accommodates angular, parallel, and axial misalignment while maintaining consistent torque transmission. It is well suited for pump drives, HVAC fan assemblies, and instrumentation setups where a compact, corrosion-resistant coupling is needed. The clamp-style hub eliminates the need for set screws, providing a secure shaft grip without marring shaft surfaces.

Key Features

• Aluminum hub construction keeps weight low while providing a rigid clamping surface
• Stainless steel bellows element resists corrosion and accommodates multi-directional misalignment
• Clamp-style attachment secures to shaft without set screws
• Rated torque of 40 inch-pounds suitable for light-duty drive applications
• Compact profile at 1.614 inches OAL and 1.28 inches OD fits space-constrained installations
• Series BWC, size code BWC41 for straightforward cross-referencing

Compatibility

Designed as an OEM-style replacement or direct-fit coupling for light-duty mechanical drive systems requiring a 3/8 inch bore bellows clamp coupling in the BWC series.

Installation Notes

Installation should be performed by a qualified mechanical technician or machine builder. De-energize and lock out all power to the drive system before installing or removing the coupling. Verify shaft diameter matches the minimum bore specification before mounting, and confirm shaft ends are clean and free of burrs. Torque all clamp fasteners to the fastener manufacturer specifications and check alignment after installation per standard mechanical drive practices.
