L075-ELE-POLY TransDrive Jaw Coupling L075 Polyurethane Spider Element

The polyurethane jaw coupling element is designed for use with L-type jaw couplings, compatible with brands such as Lovejoy and similar industry-standard hubs. The insert, also known as a spider, is constructed from durable polyurethane (urethane) elastomer, offering high torque capacity and flexibility for a range of mechanical applications.

The coupling element fits between two hubs to transmit torque while accommodating minor misalignment (up to 1° angular and 0.015" parallel misalignment). It is engineered to dampen vibration and absorb shock, reducing wear on connected equipment. The polyurethane material provides good resistance to oil, chemicals, and abrasion, and does not require lubrication or regular maintenance.

Typical applications include pumps, compressors, conveyors, and other machinery where reliable, maintenance-free torque transmission is required. The element is available in standard sizes to match L-type hub configurations and is rated for high RPM and torque loads.
