L190U Insert | L190U Coupling Insert - L190U Spider (Urethane)

L190U insert is a Urethane jaw-coupling insert with good flexibility and medium soft torsional stiffness. L190U inserts are also called L190U spiders and are used within L190 coupling hubs. The insert is the critical component allowing flexibility and is placed between the jaw hubs, preventing metal-on-metal contact. More specifically, the L190U coupling insert is made from high-quality Urethane, which is a polyurethane material that is orange in color. The material can operate in temperatures ranging from -30F to +160F and has good oil and chemical resistance; for more information on jaw coupling inserts, visit our main Jaw Coupling page or contact our customer support team.
