What ANTEX does
ANTEX Corporation (株式会社アンテックス) is a Japanese manufacturer and distributor of forged products, founded in 1917 as Ando Iron Works and renamed in 1992. The company specializes in large slewing bearings — precision rotation components used in construction machinery (hydraulic excavators, mini excavators, mining excavators, crawler cranes, tower cranes, deck cranes, shield excavation machines), wind turbines, industrial machinery (parking turntables, carousels, welding positioners), and telecommunications infrastructure (parabolic antennas). ANTEX holds over 70% domestic Japan and over 40% global market share in hydraulic excavator slewing bearings, supplying virtually every major Japanese construction equipment OEM (Komatsu, Caterpillar Japan, Hitachi CM, Kobelco, Sumitomo, Takeuchi, Yanmar, Mitsubishi Heavy Industries) plus international OEMs including Caterpillar entities in the US, Brazil, and France, Tata Hitachi, HIDROMEK, and SENNEBOGEN.
The company's core technical asset is an integrated in-house production system spanning the full value chain: steel stock cutting, forging, heat treatment, machining, gear cutting, induction quenching, raceway surface finishing, mounting hole processing, assembly, and inspection. Proprietary ring rolling mill technology has been developed in-house since 1965, and the company operates a 3,500mm 3D measuring machine capable of 0.05mm roundness tolerance. Operations are conducted across four facilities: headquarters in Tokyo, three plants in Takahagi, Ibaraki Prefecture (Takahagi Factory established 1980, 2nd Factory 2007, 3rd Factory 2010), and a wholly-owned subsidiary, ANTEX (SHANGHAI) CORPORATION, established in 2004. Supporting product lines include forged rings (600-2,400mm diameter), welded structure gears, and contract processing services. In October 2024 the company launched a new small-diameter thin turntable product called "Rakkaru" to extend into adjacent compact applications.
ANTEX operates a direct B2B enterprise sales model, with sales representatives visiting customers for technical consultation and producing custom quotes based on customer specifications and drawings. Pricing is not publicly disclosed and is determined per order. The company is privately held with no disclosed external investors, remains led by the founding Ando family (current President Yohei Ando), and reports annual revenue of 11.313 billion JPY for the fiscal year ending September 2022. ISO 9001, ISO 14001, and ISO 45001 certifications from Lloyd's Register QA cover the major production sites.
