Product Description

RU42 RU42UU 20x70x12mm High Accuracy Turntable Non Gear Slewing Bearing Ring For Robot Arm

Their rollers between the inner ring and the outer ring, the interval to intersect at right angles to each other are arranged.
They can withstand the load from all directions (eg axial thrust load or momentum, etc.). Because the surface of the roller and the track into a linear contact and therefore, the bearing load and by the possibility of elastic deformation is small. This type of bearings are widely used in industrial automation, such as robots, machine tools and medical facilities, and need high rigidity, high speed close and still ensure accurate the occasion.
RU series crossed cylindrical roller bearings, because the outer ring and inner ring have mounting holes, there is no need to fix the flange and support seat during installation. In addition, since the outer ring and the inner ring are of integral structure, the installation has almost no effect on performance, so stable rotation accuracy and torque can be obtained. Suitable for occasions where the outer ring and inner ring rotate.

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.
