Sankyo 7TC-10A Torque Limiter Overload Protector is a coupling‑type torque limiter in Sankyo Seisakusho’s TC Series, designed to protect driven equipment by mechanically disconnecting torque when the preset limit is exceeded. For the 7TC family, the tripping torque ranges from 20 to 350 N·m, it fits shafts with a diameter of 60–80 mm (A), and the unit for 7TC has a moment of inertia of about 5.8×10^-3 kg·m^2; its ball‑and‑roller‑pocket mechanism provides precise, low‑hysteresis trips. As a safety device, it protects drives and gear trains in automation, conveyors, and other mechanical systems from overload.
