We are capable of producing large swing bearings for hydraulic excavators with a maximum diameter of 3,500mm.
We are capable of producing large slewing bearings with a minimum diameter of 600mm to a maximum diameter of 3,500mm. Our strength lies in our integrated production process, allowing us to respond flexibly with low prices, short delivery times, and high quality. Furthermore, the rubber seals (dust seals) used in our designed complete slewing bearings are of the "embedded type," which do not require adhesive during installation, unlike conventional dust seals. This eliminates the risk of detachment due to adhesive degradation, ensuring quality and reliability. Additionally, the replacement of dust seals during maintenance is made easier as no adhesive is used.

Company information
Our company was founded in 1917 (Taisho 6) as a manufacturer and seller of forged products, and we expanded our business by developing the "ring rolling mill" in 1965 (Showa 40). As a fully integrated production facility, we hold a significant market share both domestically and internationally for our main product, swing bearings for hydraulic excavators, and we are a dynamic company that actively promotes technological development and equipment enhancement. Currently, we receive support for a wide range of products, not only for construction machinery such as hydraulic excavators but also for swing bearings and forged ring products aimed at industrial machinery and production equipment.
