Lovejoy 68514425308 Flexible Coupling Spider Hytrel L070

Product Description

The LOVEJOY 68514425308 is a Hytrel flexible coupling spider designed for use in the L070 jaw-type coupling series. The spider element seats between two mating hubs and transmits torque while absorbing shock and dampening vibration. It accepts a maximum bore diameter of 3/4 inch and measures 1.36 inches in outside diameter with an overall length of 2.0 inches. Hytrel construction provides resistance to oil, flexing fatigue, and moderate chemical exposure. The rated torque capacity is 114 inch-pounds (12.90 N/m). Licensed trades and mechanical contractors install this element as the consumable wear component in flexible drive couplings on pumps, blowers, compressors, and similar rotating equipment.

The L070 spider is suited for light-duty industrial and commercial mechanical drive applications where a jaw coupling connects a motor shaft to a driven component. Common install scenarios include small pump sets, fan drives, and HVAC equipment with close-coupled motor arrangements. This spider element is sold individually and requires two separately ordered L070 hubs to form a complete coupling assembly. One spider and two hubs are needed per complete coupling.

Key Features

• Hytrel material provides oil resistance, flexibility, and fatigue durability in demanding drive applications
• Rated torque of 114 inch-pounds for reliable power transmission in light-duty couplings
• Maximum bore diameter of 3/4 inch accommodates standard small motor and pump shaft sizes
• Outside diameter of 1.36 inches fits within the L070 coupling envelope without modification
• Overall length of 2.0 inches maintains proper hub-to-hub spacing in L070 assemblies
• Sold as a single spider element — two L070 hubs must be ordered separately for a complete coupling

Compatibility

Designed for use in the LOVEJOY L070 jaw coupling series. Two L070 hubs and one spider are required to form a complete coupling assembly. Hub compatibility is limited to the L070 series designation.

Installation Notes

Installation is typically performed by a licensed millwright, mechanical contractor, or qualified maintenance technician. De-energize and lock out the drive motor before disassembling any coupling. The spider element should be inspected for wear, cracking, or deformation at each service interval and replaced before visible deterioration leads to coupling failure. Do not force or stretch the spider during installation; seat it evenly between hub jaws by hand to avoid preloading the element.
