Precision of sealed spherical roller bearing

Precision of sealed spherical roller bearing

 

Sealed spherical roller bearing with normal Dimensional accuracy and Rotation accuracy is enough for most cases applications,the standard grade of sealed spherical roller bearing we use P0 or ABEC-1 to indicate,if high grade precision needed ,we suggest P6 (ABEC-3)grade,P5 grade is higher than P6 grade,its the highest precision on sealed spherical roller bearings,P5 grade roller bearing used in special applications on the market.

 

And the other bearing type like Machine tool spindle bearings,angular contact ball bearings,cylindrical roller bearings are all need high precision used in machine tool spindle,they can be the precision P4(ABEC-7)，P2(ABEC-9)the highest precision level.

XRB,the China Bearing Manufacturer,can supply sealed spherical roller bearing with P0,P6,P5 grade ,
all of the sealed spherical roller bearing are in our stock,we can delivery the goods within 3days for normal quatity.
