Lovejoy 68514456636 Flexible Screw Hub Anodized Aluminum

Product Description

The LOVEJOY 68514456636 is an anodized aluminum flexible screw hub designed for use in mechanical drive couplings where controlled torque transmission and shaft alignment flexibility are required. Part of the EC050 series with a Coupling Size Code of ES100, this hub accepts a minimum bore diameter of 0.25 inches and features a set screw fastening style for secure shaft engagement. The 1.0000-inch outside diameter and 1.0000-inch overall length make it a compact component suited for space-constrained drive assemblies. It is rated at 11.00 inch-pounds of torque and weighs approximately 0.07 pounds. Licensed mechanical and industrial trades professionals install this component as part of flexible coupling assemblies on rotating equipment.

This flexible screw hub is used in light-duty mechanical coupling applications where vibration dampening and minor shaft misalignment compensation are needed. Typical installations include HVAC fan drive assemblies, pump couplings, and small motor-driven equipment in both residential and commercial settings. The anodized aluminum construction keeps overall assembly weight low while providing adequate corrosion resistance for indoor mechanical environments. It is sold individually and is intended for use with compatible EC050 series coupling components.

Key Features

• Anodized aluminum construction for corrosion resistance and reduced assembly weight
• Set screw fastening style for positive shaft retention
• 1.0000-inch outside diameter fits compact coupling housings
• 0.25-inch minimum bore diameter accommodates small-diameter shafts
• Rated to 11.00 inch-pounds of torque
• EC050 series, Coupling Size Code ES100 for straightforward series matching

Compatibility

Designed for use within the LOVEJOY EC050 series flexible coupling system, Coupling Size Code ES100. Confirm mating hub and coupling element part numbers against EC050 series documentation before ordering.

Installation Notes

Installation is typically performed by a qualified mechanical or HVAC technician. De-energize and lock out all power to the driven equipment before disassembling or replacing coupling components. Ensure shaft and bore surfaces are clean and free of burrs before seating the hub. Tighten the set screw to the torque value specified in the coupling manufacturer documentation and verify shaft runout and alignment after assembly.
