 DEEP GROOVE BALL BEARINGS
    
    Deep groove ball bearings mainly take radial load as well as take moderate axial load.With less coeggicient of friction,high limiting speed,large size range and varations of structure,they are suitable for precision instruments,low noise motors,automobiles,motorcycles,and other common machinery,as a widely used type of bearings in machinery induxtry.

HRB
 SELF-ALIGNING BALL BEARINGS
    
    With two structures of bore cylindrical or taperde and retainers made of steel sheet or synthetic tesins,the bearings are characteristic of their spherically formed outer ring raceways allowing for misalignment within 3 defection between inner ring and outer ring,so as to compensate concentricity and deflection errors.

HRB
 ANGULAR CONTACT BALL BEARINGS
    
    Angular contact ball bearings are able to support radial load and axial load.As single row angular contact ball bearings can only support axial load in single direction,matched bearing mounting is often adopted to them. As matched pairs of bearings,preload for them is more convenient.
    Retainers are made of brass,synthetic resins or others subject to individual bearing features and application conditions.

HRB
 CYLINDRICAL ROLLER BEARING
    
    This type of bearings is separable.As their rollers linearly come into contact with inner ring and outer ring with less coefficient of friction ,these bearings have very good capacity of radial load,suitable for electric motors,automobiles,tranmission shafts,gear shafts and so on.Double row cylindrical roller bearings are good at the spindles of machine tools.

HRB
 SPHERICAL ROLLER BEARINGS
    
    With the same center as the bearing,the spherically formed outer ring raceway can make selfalignment.Their rolling elements linearly come into contact with the raceways of inner ring and outer ring.The bearings can take greatly radial load ,suitable for heavy machinery used in mining,metallrugical,paper-making and instructing,etc.,lndustry.

HRB
 TAPERED ROLLER BEARINGS
    
    Tapered roller bearings are generally used to support combined load mainly consisting of radial load.Their cups are separable for easy assembling,During mounting and using,radial celearance and axial clearance can be adjusted and preloaded mounting can be made.    

HRB
 THRUST BALL BEARINGS
    
    This type of bearings is separable ,which can only carry axial load,The single direction bearings of them can only carry axial load in one direction,while the double can carry slternating axial load in either diredtion.Before using they have to be preloaded.The thrust ball bearings are used in lathe centers ,automobile clutches,reducers and so on ,The double direction angular contact thrust ball bearings are suitable for machine tool spindles,while the single are used to support ball screws.

HRB
 LINEAR MOTION BEARINGS
    
    This type bearing consists of a sleeveed outer ring.multi-row balls and a retainer.It can make linear reciprocating displacement on a matching shaft,The mor the ball rows are,the less the friction force is,so that it becomes flexibility,long running life and easy maintenance and replacement.  

HRB
 TURBOCHARGER BEARINGS
    
    Turbocdarger bearings include deep groove ball bearings cylindrical roller bearings,duplex mounting angylar contact ball bearings and special type of duplex mounting angylr contact ball bearings .Deep groove ball bearings and cylindrical roler bearings mainly take radial load in high liniting speed.Duplex mouting angylar contact ball bearings can support both radial and axial loads simultaneously with a bitter displacement.
    As to bearings in higher speed and greater load applicationgs,the material of cages ytizes alloyed steel and shoule be specially treated to the surface.
