Lovejoy 68514412115 Flexible Hub Coupling 1.5 in Bore Metal

Product Description

The LOVEJOY 68514412115 is a flexible hub coupling designed to connect rotating shafts in mechanical drive systems. With a maximum bore diameter of 1.5 inches and an outer diameter of 3.75 inches, this metal hub accepts shaft sizes up to 1.5 inches and transmits torque while accommodating minor misalignment between connected shafts. The overall length of 4.5 inches suits a range of inline drive configurations. Rated to 5000 RPM, it handles moderate- to high-speed applications in industrial and commercial mechanical systems. Installation is performed by mechanical technicians and millwrights as part of pump, motor, or drive train assemblies.

This flexible hub coupling is suited for use in commercial and industrial drive applications where shaft coupling with misalignment tolerance is required. Typical install scenarios include motor-to-pump connections, conveyor drives, blower assemblies, and similar rotating equipment. The metal construction provides durability in demanding mechanical environments. The L150 size code designation makes it straightforward to cross-reference with compatible spider or insert elements in the same coupling series.

Key Features

• Maximum bore diameter of 1.5 inches accommodates a wide range of shaft sizes
• 3.75 inch outer diameter and 4.5 inch overall length for standard inline drive fitment
• Rated to 5000 RPM for moderate- to high-speed drive applications
• Metal construction for durability in industrial and commercial environments
• Coupling size code L150 for straightforward series cross-reference

Compatibility

Designed as an OEM-style replacement or new-install flexible hub coupling for rotating drive systems requiring a maximum bore of 1.5 inches and L150 series coupling components.

Installation Notes

Installation is typically performed by a licensed millwright or mechanical technician. Disconnect and lock out all power to the drive system before servicing any shaft coupling. Ensure shaft and bore surfaces are clean and free of burrs before seating the hub. Consult applicable machinery safety standards and the drive system manufacturer guidelines for proper hub retention and alignment procedures.
