Lovejoy 68514456656 Flexible Screw Hub 1/2 in Bore EC050

Product Description

The LOVEJOY 68514456656 is a flexible screw hub designed for use in mechanical coupling assemblies where shaft-to-shaft power transmission is required. Part of the EC050 Series, this set screw style hub accepts a minimum bore diameter of 0.5 inches and measures 1.12 inches in outside diameter with an overall length of 1.5 inches. Constructed from anodized aluminum, it offers a lightweight build with corrosion resistance suitable for industrial and mechanical drive applications. Rated at 17 inch-pounds of torque, it is sized for light-duty coupling setups. Installation is performed by mechanical technicians and maintenance professionals working on motor, pump, or drive shaft assemblies.

This screw hub is intended for use in flexible coupling systems where controlled torque transmission and slight misalignment accommodation are needed. The EC050 Series designation identifies its compatible coupling body family. Typical applications include small motor-to-pump connections, conveyor drives, and mechanical power transmission setups in commercial and light industrial environments. The anodized aluminum construction keeps rotating mass low, which is beneficial in variable-speed or high-cycle drive systems.

Key Features

• Set screw style retention for secure shaft engagement without a keyway requirement
• Anodized aluminum construction provides corrosion resistance at reduced weight
• 0.5 inch minimum bore diameter accommodates common small-shaft motor outputs
• 1.12 inch outside diameter and 1.5 inch overall length for compact coupling assemblies
• 17 inch-pound torque rating suits light-duty mechanical drive applications
• EC050 Series coupling size code for straightforward replacement and cross-referencing

Compatibility

Designed as an OEM-style replacement screw hub for EC050 Series flexible coupling assemblies using a set screw hub configuration with a 0.5 inch bore.

Installation Notes

Installation is performed by qualified mechanical or maintenance technicians. Disconnect and lock out all power to the drive system before handling coupling components. Verify bore diameter and hub series match before installation. Set screws should be tightened to the coupling manufacturer's specification using the appropriate hex key; do not overtighten, as this can damage the hub bore or shaft surface.
