  4HP muti-disc pilot mount clutches provide big torque in a small package. Available in 7 sizes with static torque up to 10000 in-lbs at 80 psi, bores up to 2.375 in. Maximum RPM dependent on torque/air pressure setting. The pilot accepts pulleys, sprockets, and Nexen couplings. More durable, and higher RPM than the LSCC clutch series. Ideal for conveyor and other high torque low RPM applications. Consult Nexen for use in cyclic applications, or use as a brake. Inch product with a metric bore.
