Case Studies

High-Speed Cartridge Bearing

High-Speed Cartridge Bearing

Our reliable assembly technology enables cartridge integration, achieving high-precision shaft alignment. This contributes to the quiet operation and extended lifespan of both our products and their bearings. It's ideal for high-speed rotation applications, including those reaching 100,000 rpm.

Point

Application Examples

High-Precision Assembly

High-Precision Assembly

We handle even complex bearing assemblies with high precision, using our reliable press-fitting, bonding, and preloading techniques. This ensures smooth, consistent rotation even after assembly. We also offer various threaded assemblies for easier installation, contributing to the simplification of your assembly process.

Point

Application Examples

Precision Machined Shaft

We can also offer our precision machining technology as a standalone service, leveraging our extensive bearing manufacturing know-how. We handle high-volume production of challenging eccentric machining with exceptional quality. Additionally, we provide high precision in a wide range of metal processing, including grinding and cutting.

Point

Application Examples

High-Hardness Roller

We offer high-performance rollers that achieve high hardness, long lifespan, and low wear by assembling a heat-treated and surface-treated housing with a flanged bearing.
