Lovejoy 68514410214 Flexible Coupling Hub L050 Sintered Iron

Product Description

The LOVEJOY 68514410214 is a flexible coupling hub in the L050 series, designed to connect rotating shafts and transmit torque in light-duty mechanical power transmission applications. Machined from sintered iron, this hub accepts a minimum bore diameter of 0.25 inches (1/4 inch) and measures 1.08 inches in outside diameter with an overall length of 1.72 inches. It is rated for up to 26.30 inch-pounds of torque. A complete flexible jaw coupling requires two hubs and one spider insert, which are ordered separately. Licensed trades and mechanical technicians install these components in motors, pumps, compressors, and similar rotating equipment.

The L050 flexible coupling hub is used in residential and light commercial mechanical systems where shaft misalignment compensation and vibration dampening are needed between a driver and driven component. Typical applications include small electric motor to pump couplings, HVAC fan assemblies, and general industrial power transmission setups. The sintered iron construction suits moderate-load environments. Two of these hubs paired with one spider insert form a complete jaw coupling assembly.

Key Features

• Sintered iron construction for durability in moderate-load rotating applications
• Minimum bore diameter of 0.25 inches accommodates standard 1/4 inch shafts
• 1.08 inches outside diameter and 1.72 inches overall length for compact fitment
• Rated at 26.30 inch-pounds of torque capacity
• L050 series sizing for consistent compatibility with matching L050 hubs and spiders
• Sold individually — two hubs and one spider required for a complete coupling assembly

Compatibility

Designed for use in L050 series jaw coupling assemblies. Two hubs and one L050 spider insert are required to complete the coupling. Verify bore diameter and series designation before ordering to confirm fitment with the target shaft and mating components.

Installation Notes

Installation of flexible jaw couplings is typically performed by a licensed millwright, mechanical technician, or HVAC technician. Disconnect and lock out all power to the drive system before beginning installation or removal. Ensure shaft and bore dimensions are confirmed before pressing or securing the hub. Do not exceed the rated torque of 26.30 inch-pounds to avoid premature wear or coupling failure.
