Lovejoy 68514412117 Flexible Hub Coupling 1.625 in Bore

Product Description

The LOVEJOY 68514412117 is a flexible hub coupling designed to connect rotating shafts in mechanical power transmission applications. With a maximum bore diameter of 1.625 inches, an outer diameter of 3.75 inches, and an overall length of 4.5 inches, this coupling accommodates angular and parallel misalignment between drive components. Constructed from sintered iron, it delivers durable performance in industrial and commercial drive train setups. Licensed mechanics, millwrights, and HVAC equipment technicians commonly install this type of coupling on motor-to-shaft connections where vibration dampening and flexible engagement are required.

This flexible hub coupling is suited for use in motor drive assemblies, pump systems, compressor drives, and fan shaft applications found in commercial HVAC equipment, light industrial machinery, and mechanical systems requiring shaft-to-shaft torque transfer. It is rated to 5000 RPM, making it appropriate for medium-speed motor applications. The L150 coupling size code identifies the hub series and allows cross-referencing with matching spider inserts and mating hub components in the same coupling family.

Key Features

• Maximum bore diameter of 1.625 inches accommodates a range of shaft sizes
• Sintered iron construction provides strength and wear resistance
• 3.75 inch outer diameter and 4.5 inch overall length suit standard motor coupling clearances
• Rated to 5000 RPM for medium-speed drive applications
• L150 coupling size code for straightforward spider and mate-hub pairing

Compatibility

Designed as an OEM-style replacement or service hub for flexible jaw-type coupling assemblies in the L150 size series, compatible with matching spider elements and mating hubs of the same coupling size code.

Installation Notes

Installation should be performed by a qualified mechanic or technician. Always de-energize and lock out the drive motor before removing or installing any coupling component. Ensure shaft and bore surfaces are clean and free of burrs before fitting the hub. Verify alignment of connected shafts after installation to stay within the coupling's rated misalignment tolerances.
