ツバキ山久チエイン Product Lineup

Our company is committed to providing solutions that meet our customers' needs, focusing on three pillars: chains, precision machinery products, and conveyor systems. In recent years, driven by energy-saving and cost-reduction trends, engineering plastic chains have become widely adopted in various applications that replace traditional conveyor systems, with increasing demand not only domestically but also in overseas markets. 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. To enhance functionality and efficiency, we have significantly revamped our organizational structure. Our production base, the Kuki factory, has undergone extensive renovations and expansions, greatly increasing production capacity and completing a new factory building. We sincerely ask for your continued guidance and support. 【Business Activities】 ■ Design, manufacturing, sales, and trade of various chains, labor-saving devices, and automation equipment. *For more details, please refer to the PDF materials or feel free to contact us.

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.

The Auto Guard 820 series is a mechanical overload protection device with a plunger mechanism. It has high and stable operating torque accuracy. After activation, it resets by lightly tapping the protruding plunger after aligning the input and output positions. It is particularly suitable for machines with large torques of 2,000 Nm or more. *For more details, please refer to the PDF document or feel free to contact us.*

The Shock Guard TGE Series BT specification is a mechanical overload protection device with a ball mechanism. It has high operating torque accuracy and can return in a short time. *For more details, please refer to the PDF document or feel free to contact us.

<Shock Guard TGM Series> The Shock Guard TGM series is a device that releases overload by allowing the cam follower to rotate and slip when a torque exceeding the set value is applied. Unlike other series, the TGM series demonstrates effectiveness in protecting machinery under certain adverse conditions such as water, oil, and dust.
