BOHEMIA RINGS

What BOHEMIA RINGS does

BOHEMIA RINGS s.r.o. is a Czech manufacturer of hot-rolled seamless steel rings, founded in 1993 and headquartered in Zámrsk. The company operates a single integrated production site running the full cycle from CNC material cutting through hot forming (ring rolling and forging), heat treatment, CNC machining, and non-destructive/destructive quality control. It produces large-diameter seamless steel rings up to 4,000mm in diameter, 630mm in height, and 7 tons in weight, with 240 tons of total heat treatment capacity distributed across seven chamber furnaces and CNC machining capacity for workpieces up to 20 tons. It also holds a 3,000+ ton raw material warehouse and an in-house BRUMAG magnetic workholding technology for clamping-sensitive components.

The company serves industrial OEMs across seven identified verticals: wind energy (the largest, covering yaw and blade pitch bearing rings, main shaft bearings, couplings, gears, and brake discs), mining and mineral processing, construction and handling equipment, precision engineering (including medical imaging components), railway transport (wheel set rims), nuclear industry, and large-format flanges and compensators. It also offers contract heat treatment and machining services to external customers in automotive, aerospace, and energy sectors. Its customer-acquisition channels are direct B2B sales split between domestic (Czech Republic/Slovakia) and foreign account managers, supplemented by trade show presence at WindEnergy Hamburg and Bauma Munich.

Revenue is generated through quote-based, custom-manufactured one-off B2B sales with no public pricing. The company is a privately held s.r.o. (Czech limited liability company), wholly owned since 2018 by Třinecké železárny - Moravia Steel, a diversified Czech steel conglomerate, which provides vertical integration into raw material supply. Certifications include EN ISO 9001/14001/45001/50001, PED 2014/68/EU, AD 2000, DNVGL, DNV CP 0247, ABS, Bureau Veritas, Lloyd's Register, TPG NDT/HT, and Czech Railways, qualifying the company for wind, marine, offshore, pressure equipment, nuclear, and rail applications.
