Lovejoy 68514449983 Universal Joint Boot 10680 In/lbs

Product Description

The LOVEJOY 68514449983 is a universal joint boot designed to protect U-joint assemblies from contamination, moisture, and debris in drivetrain and mechanical power-transmission applications. With a bore depth of 1-3/8 inches and a rated torque of 10,680 in/lbs, this boot provides a durable flexible seal around the joint housing. The inside diameter measures 7/8 inches, the outside diameter measures 2.19 inches, and the overall length (OAL) is 2.77 inches. It is installed by mechanical technicians and power-transmission specialists maintaining shafts, couplings, and U-joint assemblies across industrial and commercial equipment platforms.

This universal joint boot suits applications where U-joints are exposed to grease, dirt, water ingress, or environmental contaminants that accelerate wear. Typical installations include industrial machinery, mechanical drive systems, and equipment requiring scheduled U-joint maintenance. The compact dimensions and torque capacity make it appropriate for medium-duty shaft assemblies. Sold in a package quantity of two, it supports replacement of boots on both ends of a U-joint during a single service visit, which is standard practice to maintain balanced protection.

Installation Notes

Installation is typically performed by a licensed mechanic or power-transmission technician. Disconnect and de-energize all associated drive components before removing the existing boot. Ensure the joint is clean and re-greased per the equipment manufacturer's service interval before seating the new boot. Inspect the retaining hardware and joint yokes for wear during the same service visit.
