Lovejoy 68514412105 Flexible Hub Coupling 7/8 in Bore

Product Description

The LOVEJOY 68514412105 is a flexible hub coupling designed for connecting rotating shafts in mechanical drive systems. With a maximum bore diameter of 7/8 inches and an outer diameter of 3-3/4 inches, this coupling accommodates moderate torque loads while absorbing vibration and minor shaft misalignment. The overall assembly length is 4-1/2 inches. Constructed from sintered iron, the hub offers good wear resistance and dimensional stability under load. This coupling is rated for operation up to 5000 RPM, making it suitable for a broad range of motor and pump drive applications. Maintenance technicians and mechanical contractors install this component as part of new builds or direct-drive replacements.

This flexible hub coupling is used in HVAC, pump, compressor, and light industrial drive assemblies where two shafts must be joined with a degree of flexibility to compensate for angular or parallel misalignment. The L150 coupling size code identifies its fit within the standard jaw-style flexible coupling family. It is appropriate for residential and commercial mechanical system applications wherever the bore and OD dimensions match the driven equipment shaft and housing requirements.

Key Features

• Maximum bore diameter of 7/8 inches accommodates common motor and pump shaft sizes
• Sintered iron construction provides wear resistance and load-bearing durability
• 3-3/4 inch outer diameter with 4-1/2 inch overall length fits standard L150-series coupling housings
• Rated to 5000 RPM for use across a wide range of rotational drive speeds
• Flexible hub design absorbs vibration and minor shaft misalignment to protect connected equipment
• L150 coupling size code for straightforward cross-reference and replacement ordering

Compatibility

Designed as an OEM-style replacement hub for L150-size flexible jaw coupling assemblies. Compatible with standard L150 coupling spiders and mating hubs where a 7/8 inch maximum bore and 3-3/4 inch OD are required.

Installation Notes

Installation should be performed by a qualified mechanical or HVAC technician. Disconnect and lock out all power to the drive system before removing the existing coupling or installing this hub. Ensure shaft and bore surfaces are clean and free of burrs before pressing or sliding the hub into position. Do not exceed the published maximum RPM rating for the assembled coupling system.
