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.

Bearing types and Bearing meaning
Rolling: the support load and moving parts relative to each other intercropping bearing rolling motion, which includes raceway parts and with or without isolation or rolling the guide member groups. Can be used to bear radial, axial or radial and axial joint load.
Angular contact bearing manufacturer ball and ring nominal contact angle greater than 0 °, but less than 90 ° bearing.
Spherical bearings: spherical and wide inner ring with locking bearing to the heart. Mainly for the simple shell.
Linear motion bearings: two raceways in the rolling direction relative linear motion bearing.
Ball bearings: rolling a ball bearing.
Deep groove ball bearings: Each ring has a cross-section of about one third of the circumference of the ball type raceway continuous groove radial ball bearings.
Thrust ball bearings: rolling a ball thrust bearing.
Roller bearings: rolling element is a roller bearing.
Cylindrical roller bearings: rolling body is cylindrical roller bearing to the heart.
Tapered roller bearings: rolling body is tapered roller bearing to the heart.
Needle roller bearings: rolling body is a needle roller bearing to the heart.
Spherical roller bearings: rolling body is convex or concave spherical roller tune heart aligning roller bearings. Convex spherical roller bearings, the outer ring has a spherical raceway; concave roller bearings, the inner ring has a spherical raceway.
Thrust roller bearings: rolling element is a roller thrust bearing.
Thrust cylindrical roller bearings: rolling body is cylindrical roller thrust bearing.
Thrust tapered roller bearings: rolling body is tapered roller thrust bearing.
