Lovejoy 68514477389 Flexible Bellows Clamp 3/4 in

Product Description

The LOVEJOY 68514477389 is a clamp-style flexible bellows coupling designed for shaft-to-shaft connections in mechanical drive applications. The aluminum hub provides a lightweight, corrosion-resistant body, while the stainless steel bellows element delivers torsional flexibility and misalignment compensation. With a 3/4 inch minimum bore diameter, 1.77 inch outside diameter, and an overall length of 2.48 inches, this compact coupling suits installations where space is limited. It is rated for up to 159 inch-pounds of torque. Licensed mechanical contractors, millwrights, and pump technicians typically install this type of coupling in HVAC, pump, and light industrial drive systems.

This coupling is suited for residential and light commercial mechanical systems where flexible shaft couplings are required to connect motors, pumps, or other rotating equipment. The clamp-style design allows for straightforward installation without requiring keyways or set screws, making it a practical choice for retrofit and new installation work. The stainless steel bellows accommodates angular and axial misalignment while maintaining positive torque transmission across the drivetrain.

Key Features

• Clamp-style design simplifies installation and removal without keyways
• Aluminum hub construction reduces overall assembly weight
• Stainless steel bellows element provides torsional flexibility and misalignment compensation
• 3/4 inch minimum bore diameter fits common shaft sizes in HVAC and pump applications
• Rated to 159 inch-pounds torque capacity
• Compact 2.48 inch overall length suits space-constrained installations

Compatibility

Designed as an OEM-style replacement or direct-fit flexible bellows coupling for mechanical drive systems requiring a 3/4 inch bore clamp-style shaft connection.

Installation Notes

Installation is typically performed by licensed millwrights, mechanical contractors, or pump technicians. De-energize and lock out all connected motors and drives before beginning work. Verify shaft diameter and alignment before tightening the clamp to ensure proper seating of the bellows element. Consult applicable mechanical codes and the equipment manufacturer's specifications for alignment tolerances.
