Tsubaki Nakashima Co,Ltd. products

Our high carbon chrome steel bearing balls provide high hardness, superior resistance to fatigue, outstanding wear resistance, and exceptional dimensional stability to excel in all bearing applications.

Harsh environments including chemical and food production industries require stainless steel components. Stainless Steel balls are resistant to rust and corrosion that are prevalent in these high temperature and high humidity application conditions.

Alumina oxide balls have proven capabilities with superior wear performance in corrosive environments and high temperature conditions. The material resists oxidation and is tolerant to high moisture environments, salt solutions, and many chemicals. Typical applications include pumps, valves and flow meters.

We recently added spherical rollers to its product line. The current manufacturing program consists of near net shape headed and heat-treated blanks. Typically found in industrial applications, spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions. Our rollers are manufactured to extremely tight tolerances, improving the overall quality and performance of a spherical bearing.

Solid plastic balls are a light-weight alternative to metal balls. Less than 1/6th the weight of metal and ? the weight of aluminum, advances in plastic material formulations and thermoplastic products can even outperform metal in certain applications. The balls can be used in applications requiring light weight, noise reduction, corrosion resistance or color. Common applications are lightweight bearings, check valves, and plug balls.

We are one of the largest manufacturers in Japan of long ball screws longer than 6 meters. Our products are highly valued by machine manufacturers internationally. We meet the rigorous demands for high accuracy. Long ball screws are utilized in machine tools and other applications that require large workpieces.

High Rigidity: For machines that require higher rigidity, we provide ball screws that meet your stability and longevity requirements. Customize: Please contact us for more information about large diameter products which we are uniquely qualified to manufacture.

The iron and steel industry requires stable operation under harsh conditions of high temperature and high pressure. We provide safe and reliable products that are resistant to wear and corrosion, high temperature and special gases (e.g. COG, LDG, BFG). We also provide post-delivery support to meet individual customer needs.
