A simple mechanical protection device with low cost and excellent versatility, using a friction type.
A torque limiter is a device that slips the friction plate and center member when a load exceeding the set limit is applied, allowing it to relieve overload by spinning freely. This effectively protects the safety of machinery.

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.
