ZARN ball screw support special bearings

With the development of machine tools and equipment, high-precision, high-efficiency become important technical characteristics of the machinery industry, ball screw support bearing moving away from the traditional structure of matched angular contact ball mode, switching to needle roller/cylindrical roller thrust bearing structure.
Product features
Needle/ thrust cylindrical roller bearing used outer ring thickened of needle roller bearings and two columns thrust cylindrical roller bearing of combination structure, can bear more heavy radial/axis load, has more higher radial/axial rigidity, while this series bearing axial runout accuracy can reached 1 μm, special meet current mechanical processing industry by requirements of high precision, high host and efficient features.
