KTR RK 80 Torque Limiter — Ball Detent Overload Protection for Medium Power Drives

KTR RK 80 Torque Limiter — Ball Detent Overload Protection for Medium Power Industrial Drives

The KTR RK 80 extends the torque limiter concept to medium power applications (450–900 Nm), providing overload protection for conveyors, mixers, and processing equipment in Saudi industrial plants.

Saudi mining operations at Ma aden use RK 80 torque limiters on long overland conveyor drives where conveyor belt slip or material carry-back causes periodic jam conditions. The RK 80 protects the gearbox and motor from peak stall torque that would cause expensive failures.
