Lovejoy 68514425309 Flexible Coupling Spider Hytrel L075

Product Description

The LOVEJOY 68514425309 is a Hytrel flexible coupling spider element designed for use in jaw-type flexible shaft couplings. The spider fits between two mating coupling hubs, transmitting torque while absorbing shock and damping vibration between connected shafts. Rated at 227 inch-pounds of torque, this spider accommodates a maximum bore diameter of 7/8 inch and measures 1.75 inches in outside diameter with an overall length of 2.12 inches. It is part of the L075 coupling series. Installation requires two separate hub components ordered independently to complete the coupling assembly.

This spider element is suited for light-duty power transmission applications including pumps, compressors, fans, and conveyor drives in both commercial and industrial settings. It is appropriate wherever a flexible jaw coupling is used to connect motor shafts, pump shafts, or similar rotating equipment requiring misalignment tolerance and vibration isolation. The Hytrel material provides good chemical resistance and maintains flexibility across a range of operating temperatures, making it a dependable choice for general-purpose mechanical drive applications.

Key Features

• Hytrel construction offers chemical resistance, flexibility, and durability in drive applications
• Rated torque of 227 inch-pounds suitable for light-duty power transmission
• Maximum bore diameter of 7/8 inch accommodates common shaft sizes in the L075 series
• Outside diameter of 1.75 inches with an overall length of 2.12 inches for compact installation
• Fits L075 series jaw couplings — order two hubs separately to complete the coupling assembly

Compatibility

Designed for use with LOVEJOY L075 series jaw coupling hubs. Two hubs and one spider are required for a complete coupling assembly. Specific hub part numbers should be selected based on shaft bore requirements.

Installation Notes

Installation is typically performed by a mechanical or maintenance technician. De-energize and lock out all rotating equipment before beginning work, following applicable LOTO procedures. Ensure both hub bores and shaft surfaces are clean and free of burrs before pressing or sliding hubs onto shafts. Do not hammer directly on the spider element, and verify proper hub alignment before returning the drive to service.
