KTR TU 65 Torque Limiter — Automatic Disconnect for Overload Protection

KTR TU 65 Torque Limiter — Automatic Shaft Disconnect on Overload for Saudi Industrial Protection

The KTR TU 65 torque limiter provides automatic mechanical overload protection by disengaging the drive shaft when torque exceeds a pre-set threshold.

Saudi cement plants in Riyadh and Qassim use TU 65 torque limiters on limestone crusher drives, kiln feed conveyors, and finish mill drives where material jams cause motor stall conditions. The TU 65 disengages within milliseconds of overload, protecting gearbox and motor from stall current damage.
