High-speed precision bearings as Luoyang Bearing Science Technology Co., Ltd., one of the pillars of products,Rolling mill bearing has been formed to precision machine tool spindle bearings, rolling screw bearings, turntable bearings, high-speed spindle bearings, high-speed woodworking machinery bearings, bearing the printed circuit board dedicated high-speed drilling and milling machine and marine turbocharger bearings as the leading products bearing production system.
Structure type ZYS production of high precision bearings angular contact ball bearings, including ceramic ball bearings; single, double row cylindrical roller bearings; deep groove ball bearing; three, four-point contact ball bearings; angular contact thrust ball bearing; rolling screw special ball bearings, tapered roller bearings, thrust / radial bearings and other types of bearings.
Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.
