High speed! High precision! A torque limiter that operates simultaneously with the occurrence of overload and is capable of direct motor connection (MAX 3600 r/min).
The Auto Guard 400 series is a mechanical overload protection device with a ball mechanism. When an overload occurs, the ball rolls and pops out of the pocket, cutting off the overload due to its structure, resulting in the highest operating torque accuracy among mechanical devices. (Please refer to the image.) After operation, it automatically resets when the driving side is reversed or the driven side is rotated forward. *For more details, please refer to the PDF document or feel free to contact us.* Additional Notice: All types of Auto Guard 400 Series, Sizes 2 to 5, have been discontinued as of August 1, 2025. Note: Product descriptions will remain available for a certain period after discontinuation to assist customers in considering alternative products.

Company information
Our company, as a member of the Tsubakimoto Chain Group, is dedicated to providing solutions that meet our customers' needs, focusing our business on three main pillars: chains, precision machinery products, and conveyor systems. In April 2012, we reorganized within the group, and our chain business restarted with a focus on the Tsubaki brand's top chain operations. In recent years, driven by energy conservation and cost reduction, engineering plastic chains have become widespread in various applications that replace traditional conveyor systems, with increasing demand not only domestically but also internationally. The need for products that can withstand harsh operating conditions is also growing, making it increasingly important to provide solutions through optimal products and appropriate engineering services. In this context, we have significantly revamped our structure to consolidate the group's strengths and enhance functionality and efficiency. Our production base, the Kuki Factory, underwent extensive renovations, greatly increasing production capacity, and we completed a new factory building in March 2013. We sincerely thank you for your long-standing support and ask for your continued guidance and encouragement in the future.
