Lovejoy 68514476984 Flexible Bellows Clamp 3/4 in

Product Description

The LOVEJOY 68514476984 is a clamp-style flexible bellows coupling designed for shaft-to-shaft power transmission in mechanical drive applications. The hub is machined from aluminum and paired with a stainless steel bellows element, combining light weight with corrosion resistance and torsional flexibility. It accepts a minimum bore diameter of 3/4 inches, measures 1.77 inches in outside diameter, and spans 2.48 inches overall length. Rated at 159 inch-pounds of torque, this coupling is suited for precision motion control, pump drives, and servo-driven equipment. Installation is typically performed by millwrights, mechanical technicians, or industrial maintenance professionals.

The 68514476984 belongs to the LOVEJOY BWC Series, size code BWLC63. It is a clamp-style coupling, meaning shaft retention is achieved through a clamping mechanism rather than set screws, which reduces the risk of shaft marring and simplifies alignment during installation. Common applications include connecting motor shafts to pumps, encoders, or gear reducers in light-to-medium duty industrial environments. The stainless steel bellows element accommodates minor angular and parallel misalignment while maintaining consistent torque transmission.

Key Features

• Clamp-style hub retention reduces shaft damage compared to set-screw designs
• Aluminum hub keeps rotating weight low for responsive drive systems
• Stainless steel bellows element provides corrosion resistance and torsional flexibility
• 159 inch-pound torque rating suitable for light-to-medium duty drive applications
• Compact 2.48 inch overall length fits tight shaft-to-shaft spacing
• BWC Series, size BWLC63 for straightforward cross-reference and replacement ordering

Compatibility

Designed as an OEM-style replacement or direct-fit coupling for mechanical drive assemblies requiring a 3/4 inch bore, clamp-style bellows coupling within the LOVEJOY BWC Series, size code BWLC63.

Installation Notes

Shut down and lock out all power to the drive system before beginning coupling installation or removal. Ensure both shafts are clean, free of burrs, and within the bore diameter specification before inserting. Align shafts within the angular and parallel misalignment tolerances specified in the LOVEJOY BWC Series installation guide. Tighten clamp hardware evenly and verify coupling runout before returning the drive to service.
