Lovejoy 68514410206 Flexible Coupling Hub L050 Sintered Iron

Product Description

The LOVEJOY 68514410206 is a flexible coupling hub in the L050 series, designed to transmit torque between shafts while accommodating minor misalignment in mechanical drive systems. Machined from sintered iron, this hub measures 1.08 inches in outside diameter and 1.72 inches overall length, with a minimum bore diameter of 0.25 inches (1/4 inch). It is rated for up to 26.30 in-lb of torque. The hub is one half of a complete jaw-style flexible coupling assembly and is installed by maintenance technicians and mechanical contractors in light-duty industrial and commercial drive applications.

This coupling hub is suited for use in small motor and shaft assemblies found in commercial HVAC equipment, pumps, fans, and general mechanical drive systems. A complete coupling requires two hubs and one spider insert — this listing covers a single hub only. Order one spider and two hubs to complete the coupling assembly. The L050 series is intended for light-duty torque loads with a minimum bore starting at 0.25 inches.

Key Features

• Sintered iron construction for durability in light industrial environments
• L050 series jaw-style coupling hub for flexible, misalignment-tolerant drive connections
• 1.08 inches outside diameter and 1.72 inches overall length for compact installation footprints
• Minimum bore diameter of 0.25 inches accommodates small-diameter shafts
• Rated torque of 26.30 in-lb suitable for light-duty motor and pump drives
• Sold as a single hub — two hubs and one spider required for a complete coupling

Compatibility

Designed as an OEM-style replacement or new-installation hub for L050 series jaw-style flexible coupling assemblies requiring a sintered iron hub with a minimum 0.25 inch bore.

Installation Notes

Installation is performed by qualified mechanical technicians or millwrights. Disconnect and lock out all power to the drive system before handling any coupling components. Ensure shaft and bore diameters are confirmed before pressing or keying the hub onto the shaft. Two hubs and one spider must be assembled together for a functional coupling — do not operate the drive with only one hub or without the spider insert seated properly.
