The TLD series consists of spring friction torque limiters designed to protect machinery by disengaging when torque exceeds a set limit. Available in multiple torque ratings from 2.5 to 500 N·m, the limiters feature a plastic (POM or PET) housing, iron-based sintering components, and piano wire springs. They are bidirectional, RoHS compliant, and rated for rotational speeds up to 1,000 min⁻¹. Physical dimensions vary by model, with shaft diameters of 6 mm or 8 mm and overall lengths ranging from 19.6 mm to 98.0 mm. All variants share a standard tolerance of ±0.2 mm and are suitable for applications requiring compact, lightweight overload protection.
A torque limiter is an overload protection device that immediately blocks the input and output to protect the application when the load exceeds the setting. For example, if a machine is no torque limiter and something trouble is occurred cause of something jam at the output side, a drive source such a motor may break down due to overload. On the other hand, if the torque on the input side of a motor or other device is too high, the output side may break down. By installing a torque limiter between the input and output sides, such component damage can be prevented. As soon as the torque on the output side is back to the set torque or less, it returns from the protect condition to the transmission condition.
