Sankyo 6TR-2A Torque Limiter

Sankyo 6TR-2A Torque Limiter is a compact overload-protection device for rotating machinery, delivering a defined trip torque of 19 Nm to guard drives from overload. Built by Sankyo Seisakusho, this torque limiter relies on a precise mechanical trip mechanism that engages when the torque exceeds the set limit, providing a controlled response that protects gear trains and motors from damage. Typical Sankyo torque limiters use a roller/ball-based engagement within pocketed surfaces to achieve repeatable trips with high accuracy, a design feature noted in their torque-limiter literature. The Sankyo torque-limiter family spans multiple model lines—TC, TF, and others—covering a wide range of torque ratings and mounting options, reflecting the company’s focus on robust overload protection for automation, packaging and machine-tool applications.
