The S69 series combines the space-saving advantages of the ultra-thin series with the performance characteristics of the standard series, representing a stainless steel bearing design that maximizes space efficiency. Manufactured from SUS440 stainless steel, the series ensures sufficient structural rigidity and corrosion resistance despite its extremely thin wall profile.
Bearing Features
Thanks to its lightweight internal components, the S69 series features very low starting torque, enabling rapid response to frequent start-stop cycles. This responsiveness makes it widely suitable for applications such as drone motors, handheld gimbals, and high-precision sensor spindles. Precision polishing of the SUS440 stainless steel minimizes friction between the steel balls and the raceways, resulting in excellent quiet operation.
