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.

Rolling mill bearing raceway relative displacement
If paired installation, so that one pair of bearing outer ring relative to that wide side face of wide and narrow side sealed angular contact ball bearing facing the narrow end. This can avoid additional axial force, and the shaft or housing to limit axial clearance within the range in both directions.
Its inner and outer ring Rolling mill bearing raceway relative displacement on the horizontal axis, so it angular contact ball bearing can support radial load and axial load - combined load (single row angular contact ball bearings can withstand axial load in one direction, so often paired installation).
Cage made of brass, synthetic resins, etc., depending on the bearing forms, and application conditions.
More angular contact Cross roller bearing ball bearings are manufactured abroad bearing manufacturers, domestic applied to imported equipment such as more angular contact ball bearings 3204RS, and so on.
