In the modern industrial landscape, as technology becomes more sophisticated, the demand for compact, precise, and powerful power transmission solutions is more urgent than ever. Tsubaki, with its spirit of continuous innovation, is proud to introduce a groundbreaking product: the Epsilon Chain Stainless Steel Series - The World's Smallest Roller Chain.
This is a perfect solution for big challenges in extremely tight spaces where traditional chains simply cannot fit.
1. Compact Power: The Three Superior Values of the Epsilon Chain
The Epsilon Chain is not just a compact product; it is the combination of three core values that deliver incredible performance:


-
World's Smallest Size: With a chain pitch of just 1.905mm, the Epsilon Chain is the smallest roller chain globally. This size allows it to operate effectively in applications where belts or wires were previously the only option.
Superior Strength: Despite its miniature size, the Epsilon Chain boasts an impressive tensile strength of up to 0.36kN. This ensures reliable and powerful power transmission in applications demanding high precision.
-
Corrosion Resistance: Made from stainless steel, the Epsilon Chain has excellent corrosion resistance. This makes the product durable in harsh environments, including those that are frequently exposed to water for cleaning.
2. The Difference That Makes the Power: Rollers and High Rigidity
One of the most unique aspects of the Epsilon Chain, compared to other small chains, is that it is equipped with rollers.
-
The Difference from Rollers: Unlike many small chains that are bushed chains, the Epsilon Chain has rollers. This not only increases the service life of the sprockets but also reduces friction, leading to smoother power transmission.
-
High Rigidity: The Epsilon Chain has superior rigidity, which prevents "flex" during motion. This characteristic makes it an ideal choice for extrusion applications or mechanisms that require very high precision.
-
High Flexibility: With its excellent bending capability, the Epsilon Chain surpasses wire ropes, avoiding the risk of deformation or breakage, and ensuring absolute reliability in operation.
3. Diverse Applications and Unlimited Growth Potential

Thanks to its outstanding advantages in size, strength, and durability, the Epsilon Chain has opened up new possibilities for diverse applications:
-
Medical Devices: Applications in endoscope control units and robotic surgical arms.
-
Robotics and Automation: Used in sophisticated robot end effectors, crop harvesting robots, and assistive devices.
-
Wearable Technology: Applied in assist suits and prosthetic arms.
-
Electronics and Automation: High-precision power transmission mechanisms in compact devices.
The Epsilon Chain is more than just a product; it is a testament to Tsubaki's innovation and commitment to creating efficient, sustainable power transmission solutions for the challenges of the future.
