Lovejoy 68514412292 Flexible Hub Coupling 1-1/4 in Bore

Product Description

The LOVEJOY 68514412292 is a flexible hub coupling designed for power transmission applications in mechanical drive systems. With a maximum bore diameter of 1-1/4 inches and an outer diameter of 4-1/2 inches, this hub fits into the L190 coupling size family and handles shaft speeds up to 5,000 RPM. The sintered iron construction provides reliable strength and wear resistance in demanding industrial and trade environments. This type of coupling is typically installed by millwrights, HVAC technicians working on mechanical drive assemblies, or industrial maintenance professionals who require precise shaft alignment management.

Flexible hub couplings in this size range are commonly used in light to medium-duty drive systems including fan and blower assemblies, pump drives, and compressor shaft connections. The L190 size designation makes this hub compatible with the corresponding spider insert and mating hub components used in standard jaw-type flexible coupling configurations. An overall assembled length of 4.88 inches suits typical inline shaft arrangements where angular and parallel misalignment must be absorbed without transmitting shock loads downstream.

Key Features

• Maximum bore diameter of 1-1/4 inches accommodates common shaft sizes in fan and pump drives
• Sintered iron construction offers consistent density and resistance to wear under rotational load
• Rated to 5,000 RPM for compatibility with higher-speed motor and blower applications
• L190 coupling size code enables straightforward identification of matching spider inserts and mating hubs
• 4-1/2 inch outer diameter and 4.88 inch overall length suit standard inline drive configurations

Compatibility

This hub is designated as coupling size code L190 and is designed to pair with corresponding L190-series spider inserts and mating hub components in jaw-type flexible coupling assemblies.

Installation Notes

De-energize all drive equipment and lock out the power source before removing or installing any coupling component. Inspect shaft keyways and set screw threads before mounting the hub to ensure proper engagement and concentricity. A qualified millwright or mechanical technician should verify shaft alignment within manufacturer tolerances before operating the assembled drive. Consult applicable ANSI and OSHA mechanical power transmission standards for guarding and safety requirements.
