Nu-Teck torque limiter is a protective device that limits torque transmitted in a drive system by slipping when torque demand exceeds a preset value as a result of shock loads, over loads, or machine jams. It automatically re-engages when the over load torque has passed, no resetting is required. The Nu-Teck torque limiter prevents machine damage and eliminates costly downtime. The Nu-Teck torque limiter utilises spring-loaded friction surfaces for its operations. The slip torque is preset by adjustment of the spring force. The Nu-Teck torque limiter can be used with a sprocket, gear, sheave or flange plate as a center member that is clamped between two friction facings.
