Latest company news about Micro External Teeth Slewing Bearing Excavator Turntable Slewing Bearing Ring

Slewing bearings are large-sized bearings which can accommodate a combined load, i.e., radial loads and tilting moment. They are usually provided with holes for fixing bolts; internal, external or no gear; and lubrication holes and seals, which allow a compact and economical arrangement. In addition, they often enable the elimination of many components necessary in the classical bearing arrangement.

Company Profile

 

DRACHMA (ZHANGJIAGANG) MATERIAL CO.LTD has two main production plants. Zhangjiagang plant is responsible for the rough forming of workpieces, mainly forging process; While Hangzhou plant is mainly responsible for precision machining, welding and inspection of products. We implement this layout mainly to use the industrial advantages of each region to achieve maximum economic benefits.

 

Traditional processing enterprises often do not have such ability, the lack of blank forming ability is unable to achieve the optimal use of materials, resulting in excessive processing allowance, long cycle, high cost. Zhangjiagang is located in the southern jiangsu province, which has the strongest forging capacity in China. It has a good supporting industry and can realize the diversified production of forging and pressing blanks. Thanks to this, the product cycle of our company is faster, the cost performance is higher, and the forging products have better mechanical properties than the products directly processed by rod or plate.

 

In addition, our company has strong welding ability, which can weld and assemble parts to achieve system delivery. We adopt the mode of automatic robot welding and manual precision welding to achieve flexibility and high quality.
