In a busy automotive assembly line, a robotic arm repeatedly tightens bolts to a precise torque. When a bolt seizes, the Canon FE3-9778 torque limiter instantly disengages, preventing gearbox damage and costly downtime. This friction-based unit offers continuously adjustable torque from 5 to 50 Nm, with a 15 mm bore for shaft-to-shaft coupling. Its zero-backlash design ensures precise positioning, while the automatic reset and mechanical overload indicator keep operations running smoothly.
