Industrial maintenance folks, this is a Lovejoy WE2 series tire coupling element. It's the flexible, donut-shaped insert that goes inside a Lovejoy coupling hub to connect two shafts (like a motor to a pump). This specific one has a polyether urethane tire with a steel insert for strength. The outside diameter is 3.70 inches, the length is 3.08 inches, and it's rated for 190 inch-pounds of torque with a max RPM of 7500. It can handle a wide temperature range from -40°F to 200°F. The \WE2\ is the body style. These couplings are used everywhere – on pumps, motors, compressors, conveyors – to connect shafts while allowing for a bit of misalignment, absorbing shock, and dampening vibration. When the old urethane tire cracks or wears out, you just replace this element instead of the whole coupling, which saves money and downtime. This is a standard replacement part. Just match the WE2 style and the size (3.70\ OD). Slide out the old one, slide this new one in between the two metal hubs, and you're back in business. A simple, cost-effective fix to keep your machinery running smoothly.
