Lovejoy 68514449967 Universal Joint Boot 540 In/lb

Product Description

The LOVEJOY 68514449967 is a universal joint boot designed to protect U-joint assemblies from contamination, moisture, and debris in mechanical drive applications. This boot fits over the joint to seal out dirt and retain lubrication, extending the service life of the connected U-joint. It is rated for 540 inch-pounds of torque and features an 11/16-inch bore depth, with a 5/16-inch inside diameter. Installation is handled by mechanical technicians and drive-train service professionals working on power transmission systems in industrial, agricultural, or light equipment applications.

This universal joint boot is suited for use in rotary shaft assemblies where U-joints require a protective covering against environmental exposure. Typical applications include small drive shafts, steering linkages, and power take-off assemblies in equipment where joint longevity is a maintenance priority. The package includes 2 boots per unit, making it practical for replacing boots on both ends of a joint assembly in a single service call.

Installation Notes

Installation is typically performed by a qualified mechanical technician.
