PT Tech’s UJT-500 Series is a maintenance-free continuously engaged friction type torque limiter. The torque setting is pre-set at the factory. The tamper resistant torque setting can only be changed by installing a different complement of spring cup bolts thus preventing equipment damage due to unauthorized adjustment.
The spring cup bolts are pretested and pre-shimmed to maintain a consistent and predictable force on the friction material. They eliminate the need to adjust the torque limiter torque setting at installation and throughout its wearlife. The spring cup bolts are color-coded according to their strength. The torque is easy to verify by counting the quantity and color of spring bolt assemblies.
