The world largest 18,500 tons oil hydraulic press and 750 tons/m forging manipulator were completely installed in CITIC HEAVY INDUSTRIES CO., LTD on November 26, 2010, now they have began to enter the testing phase.
It is reported that this world largest oil hydraulic press is the core equipment of "New Heavy Machine Engineering", which has invested 3.9 billion yuan by CITIC HEAVY INDUSTRIES CO., LTD. The height of this equipment is 20m from ground level, depth of 7.5m, and the whole machine weights about 4,000 tons. The annual production capacity of large forgings in CITIC HEAVY INDUSTRIES CO., LTD could reach 150,000 tons after this "giant" has been put into use.
One of the core components of this "giant" oil hydraulic press is oil hydraulic press supporting bearing E8331-7P which was independently developed, designed and produced by Luoyang Heavy-duty Bearing Co., Ltd, now it has also entered the operating phase and accepted the quality & performance testing together with the oil hydraulic press. The outer diameter of this supporting bearing is Φ3400mm, belongs to the rare single-row double-row cylindrical roller、single row ball composite structure in China. At the same time, the application of LTZC E8331-7P bearing in this world largest, most advanced "giant" oil hydraulic press fully proved the technical strength and advanced production technology of Luoyang Heavy-duty Bearing Co., Ltd in China's bearing area.
