Lovejoy 68514411993 Flexible Coupling Spider Hytrel L150

Product Description

The LOVEJOY 68514411993 is a Hytrel flexible coupling spider designed for use in the L150 jaw-type coupling series. The spider element sits between two mating hubs and transmits torque while absorbing shock loads and dampening vibration. Hytrel material provides a balance of flexibility and load capacity, making it suitable for general-purpose power transmission applications. This spider is rated at 3,708 in/lb (419 N/m) of torque. One spider and two separately ordered hubs are required to assemble a complete L150 coupling. Licensed mechanics, millwrights, and maintenance technicians typically handle installation in industrial and light commercial drive systems.

This spider element is used in rotating shaft coupling assemblies where misalignment compensation and vibration isolation are needed. Typical applications include pump drives, compressor drives, conveyor systems, and fan drive assemblies. The L150 coupling size accommodates moderate torque loads in both horizontal and vertical shaft orientations. The Hytrel spider is a common choice when some chemical resistance and flexibility under cyclic loading are required. To complete the coupling assembly, two L150 hubs must be ordered separately alongside this single spider element.

Key Features

• Hytrel material offers flexibility, chemical resistance, and durability under cyclic torque loads
• Rated torque of 3,708 in/lb (419 N/m) for reliable power transmission in L150 applications
• 3.75 inch outside diameter and 4.5 inch overall length sized for L150 jaw coupling series
• Spider-style element absorbs shock and dampens vibration between drive and driven equipment
• One spider completes the coupling assembly when paired with two L150 hubs ordered separately

Compatibility

Designed for use in the LOVEJOY L150 jaw-type flexible coupling series. Two L150 hubs are required along with this spider to form a complete coupling assembly. Hub bores and keyways are determined separately at time of hub selection.

Installation Notes

Installation should be performed by a qualified millwright or maintenance technician. De-energize and lock out the drive system completely before disassembling any coupling components. Ensure shaft alignment is within the coupling series tolerances before inserting the spider element between the hubs. Do not operate the coupling with a damaged or deformed spider, as this can result in unexpected equipment failure.
