Accuracy
According to the International Standard.the Accuracy of SL Bearing can be divided into five grades normal Grade 0,High Grade 6,Accurate grade 5,Over Accuracy Grade 4,and over the 4th grade2.
The grade of tolerance is in accordance with the standard of GB/T307.

Vibration and Noise
According to its accuracy Grade of the vibration value of the Noise of SL Bearing (Vibration)it is to be divided in Z1,Z2,Z3three groups.It can also be in accordance with Speed Grade of Vibration Value (µm/s) V1、V2、V3 Groups to measure its vibration.(to see table 4.)
If users have no requirement for vibration.The Normal Grade Bearing usually to be leaving out of the factory is in Vibration Value of Z1 Group.
Bearing Vibration speed Grade can not be over the following Values（dB）

Clearance
In accordance with standard of ISO 5753.The radial Clearance of SL Bear can be divided into five groups.
Radial Clearance Value without load See Table 6.
Generally it is according to the manufacturing and installation of the basic group of Clearance.The users who need the Radial Clearance except the basic group should put down their requirements in the contract.
