NKIA series (one-way) radial needle roller bearings and one-way angular contact ball bearings for axial light load; NKIB series (two-way) radial needle roller bearings and two-way angular contact ball bearings for shaft light load. Needle roller / angular contact ball bearings, the needle roller bearings and contact angle of 25 ° angular contact ball bearings combined, which can withstand radial heavy load and axial light load. needle roller bearings are mainly subjected to radial loads, and 25 ° angular contact ball bearings are mainly subjected to axial loads. The series of bearings with compact structure, small installation space, high rotation accuracy, widely used in machine tools, metallurgical machinery, textile machinery and printing machinery and other equipment.
