Lovejoy 68514458610 Flexible Oldham Coupling 3/16 Inch

Product Description

The LOVEJOY 68514458610 is a flexible Oldham coupling hub designed for motion control and power transmission applications where shaft misalignment compensation is required. This hub features an aluminum body paired with a polyacetal center insert, providing a lightweight, corrosion-resistant assembly with low backlash performance. It belongs to the MOL series and uses a clamp-style bore retention method for secure shaft engagement. The hub accommodates a minimum bore diameter of 3/16 inches and measures 0.789 inches in outside diameter with an overall length of 1.3 inches. Rated at 11 inch-pounds of torque, it suits light-duty drive train connections in compact machinery.

This coupling hub is used in industrial and mechanical drive applications including servo drives, stepper motor connections, encoders, and light-duty power transmission assemblies. The clamp-style design allows straightforward installation on shafts within the supported bore range. This listing covers a single hub component. To assemble a complete Oldham coupling, two hubs of the same outside diameter plus one polyacetal insert must be ordered. Bores on the two hubs can differ, making this hub suitable for connecting shafts of different diameters in the same drivetrain.

Key Features

• Aluminum hub construction for lightweight, corrosion-resistant performance
• Polyacetal center insert provides flexibility and dampens shock loads
• Clamp-style bore retention for secure, tool-assisted shaft clamping
• 11 inch-pound torque rating suited for light-duty motion control applications
• Minimum bore diameter of 3/16 inches fits compact shaft sizes
• MOL series sizing allows mixing bore diameters across hubs in a complete coupling

Compatibility

Designed for use within the LOVEJOY MOL series (size code MOL20C). A complete Oldham coupling assembly requires two hubs of the same outside diameter (0.789 inches) and one matching polyacetal insert. Hubs within the same OD size may have different bore diameters.

Installation Notes

Installation should be performed by a qualified mechanical technician. Disengage and lock out all power to connected drive equipment before installing or removing the coupling hub. Use appropriate clamp-screw tooling to secure the hub to the shaft without over-stressing the bore. Verify shaft and hub alignment after assembly to ensure the polyacetal insert seats properly within both hub faces before returning the drive to service.
