For more than 12 years the company has been developing and producing multi-row ball radial-thrust bearings with toroidal raceways for DHM's. The bearings of our production are used in bearing sections of PDM's and turbodrills operating in mud, as well as in geared turbodrills operating in oil.

Due to use of imported silicomolybdic steel of vacuum-arc remelting and high precision of production while the bearing manufacture, we have reached significant increase of load-carrying capacity and durability of the bearings. The average operation life constitutes approximately 250-400 hrs depending on drilling conditions. Except the range of the bearing standard sizes our company is developing and producing the bearings as per customers' size requirements.
