Rigaku’s Magnetic Fluid Seals

The origin of Rigaku’s magnetic fluid seal units goes back to 1952 when Rigaku commercialized a rotating anode X-ray generator for the first time in the world.

Although they were originally the built-in units for in-house products, Rigaku Mechatronics was newly established in 1989 as a manufacturer of magnetic fluid seal units based on the technologies accumulated by that time.

Our products have been widely selected as a clean shaft bearing to solve various issues in the needs from customers who put the highest priority on reliability.

As we belong to the Rigaku Group specialized in X-ray analysis instruments, we are located within the premises of Rigaku. We can provide a proposal one step ahead of others, through heat analysis simulations, magnetic fluid analyses, quantitative assessments, identification assessments, etc., by fully utilizing our analytical know-how accumulated in the development and manufacturing of analysis instruments. Also, the Rigaku X-ray analysis instruments equipped with our magnetic fluid seals have been widely used around the world and have earned the trust of our customers.

History

We are a long-established manufacturer with 30 years of history in manufacturing and development of magnetic fluid seals. We are confident that we can best any other company with the expertise we have accumulated over the past 30 years. Also, as we have never been satisfied with the status quo; we have implemented and will implement further research and development to upgrade our technologies.

Special-order products

Many of our products are special-order products for which dedicated drawings are created. According to our motto: “product development close to our customers”, we respond to various needs from a spot production for one unit to mass production, from the perspective of customers and with a strong sense of commitment. We always ask ourselves in our daily operations, “How can we provide products whose quality, cost and delivery are totally satisfactory to our customers?”

Thorough quality control

Rigaku’s magnetic fluid seals have been advanced in line with the history of semiconductors. In the semiconductor industry requiring the utmost levels of cleanliness, the same level is also required for seal parts. We don’t think that magnetic fluid seals are just the parts. We provide our products after conducting thorough pre-process cleaning of parts, post-process cleaning and other processes to eliminate causes of contamination.
