Browning Industrial JS5N Spider Coupling Insert

The Browning JS5N Neoprene Jaw-Type Coupling Insert is the flexible, non-lubricated spider element for JS5-series jaw couplings (JP5, JS5, JS5H) that transmits torque while damping shock and accommodating slight shaft misalignment. This neoprene insert features a six-lobed spider with an outside diameter of 2.6875 inches, a 5/8-inch insert thickness, six teeth, and a total weight of about 0.12 lb, with a hardness of 80 Shore. It is specified for -55 to 225 °F operating temperatures, a maximum speed of 3600 rpm, a torque rating of 38.5 in-lb, and roughly 1.1 hp at 1800 rpm; the part is unlubricated and black, designed to mate with Browning JP5, JS5, and JS5H hubs for reliable power transmission in compact drive trains.
