Lovejoy 68514412280 Flexible Coupling Spider Urethane L190

Product Description

The LOVEJOY 68514412280 is a urethane flexible coupling spider in the L190 series, designed to serve as the elastomeric insert element in a jaw-type flexible shaft coupling assembly. The spider transmits torque between two hubs while absorbing shock, damping vibration, and accommodating minor shaft misalignment. Rated at 2,592 inch-pounds of torque, it fits a maximum bore diameter of 2.125 inches and measures 4.5 inches in outside diameter with an overall length of 4.88 inches. Two separate hubs must be ordered to complete the coupling assembly. Installation is performed by maintenance technicians and millwrights in industrial, HVAC mechanical, and pump drive applications.

The L190 series spider is suited for use in light-to-medium industrial drive systems including pump couplings, fan drives, compressor drives, and general power transmission setups. The urethane material provides good chemical resistance and resilience across typical indoor mechanical room operating conditions. Because the spider is the wear element in the jaw coupling system, it is commonly stocked as a service replacement item for preventive maintenance programs.

Key Features

• Urethane construction absorbs shock and dampens torsional vibration between drive and driven shafts
• Rated torque capacity of 2,592 inch-pounds (293 Newton-meters) for L190 series applications
• Maximum bore diameter of 2.125 inches accommodates common shaft sizes in this coupling class
• 4.5 inches outside diameter and 4.88 inches overall length match L190 hub geometry
• Spider-only component — two matching hubs required to complete the coupling assembly
• Sold individually, allowing targeted replacement of the elastomeric element without replacing hubs

Compatibility

Designed for use with LOVEJOY L190 series jaw coupling hubs. Two L190 hubs must be purchased separately to complete the coupling assembly. Confirm hub series and bore size before ordering.

Installation Notes

Jaw coupling spider replacement is typically performed by a millwright or licensed mechanical technician. De-energize and lock out the drive motor before disassembling the coupling per OSHA lockout/tagout procedures. Inspect hub jaws for wear or cracking before installing the new spider element. Do not exceed the rated torque for the L190 series when sizing this coupling for a new application.
