Lovejoy 68514458110 Aluminum Hub Jaw Coupling MOL32

Product Description

The LOVEJOY 68514458110 is an aluminum hub jaw coupling designed for use with a polyacetal spider insert in the MOL series. It transmits rotational torque between two shaft ends while absorbing minor misalignment and shock loads. With a coupling size of 1.26 inches (32mm) and a torque capacity of 39.8 inch-pounds, this hub suits light- to medium-duty drive applications in mechanical, HVAC, and industrial equipment. Licensed millwrights, maintenance technicians, and mechanical contractors typically install this component during motor-to-shaft coupling assemblies or replacement service on existing equipment.

The MOL32 series hub is suited for applications where a compact, lightweight coupling is needed to connect motor shafts, pump shafts, or small drive systems. The polyacetal insert, sold separately, fits into the jaw interface between two hubs to cushion torque spikes and reduce vibration transmission. Common install scenarios include small circulator pumps, blower assemblies, and light conveyor drives found in both commercial and light industrial settings.

Key Features

• Aluminum construction for a lightweight, corrosion-resistant hub body
• MOL32 coupling size accommodates 1.26 inch (32mm) shaft interfaces
• 39.8 inch-pound torque capacity rated for light- to medium-duty applications
• Compatible with polyacetal spider insert for vibration dampening and shock absorption
• Universal jaw coupling design allows pairing with standard MOL series mating hubs

Compatibility

Designed as an OEM-style replacement or new-installation hub for MOL series jaw couplings requiring a 1.26 inch (32mm) bore interface and a polyacetal spider insert.

Installation Notes

Installation is typically performed by a licensed millwright or mechanical technician. Before servicing, de-energize and lockout the drive motor per OSHA LOTO procedures. Ensure shaft and bore surfaces are clean and free of burrs before pressing or keying the hub onto the shaft. Do not exceed the rated torque capacity of 39.8 inch-pounds for this coupling size, and always confirm the spider insert is properly seated between mating hub jaws before returning the drive to service.
