High Accuracy Spherical Roller Bearing Low Noise For Crystal Vibrator

FAG Spherical Roller Bearings 22208 Bearing 40×80×23mm Used In Crystal Vibrator

Spherical Roller Bearings FAG 22208 Bearing is one kind of spherical roller bearing design. Actually Spherical Roller Bearing also called Self-Aligning Roller Bearings, so it can be named Self-Aligning Roller Bearing FAG 22208 Bearing ,  its dimension is 40×80×23mm. it has the different dimension and the a little different design with normal chrome steel NSK 22208 bearing. Their Cage can be E/CC/CA such brass or Pressed Steel cage . The chamfer of Sealed spherical roller bearings are the same with normal design . it has the lubrication groove and three lubrication holes on the outer ring.

Many bearing user don't understand clearly about FAG 22208 spherical roller bearing installation , now let me talk about this , spherical roller bearing is consist of inner ring , outer ring , spherical rollers and cage , there are two raceway in the inner ring and one spherical raceway in the outer ring , the center of curvature of the raceway in outer ring is coincident with the centre of the bearing , so spherical roller bearing have the self-aligning function like the self-aligning ball bearing, when deflection occured between shaft and housing ,it can adjust the capacity and shaft load in double directions , Large radial load capacity are used in high capacity and shocked load, the tapered bore inner ring of the bearings can be installed directly , or using an adapter sleeve to install on the cylindrical shaft , the cage can be Pressed steel , brass materials.

Spherical roller bearing FAG 22208 bearing have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Sealded spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.

The most normal cage design of sealed spherical roller bearing is brass cage(CA) and Pressed steel cage(CC) , it adopt NRB material seals to prevent the dusty away from the internal of bearing , its better design for lubrication than open spherical roller bearing , sealed spherical roller bearing can be working reliable under the temperature -40~120 ℃.

Spherical roller bearing FAG 22208 Bearing need to be lubricated to operate stable and keep the smooth rolling between the raceway and the rollers and the cage , thus it will be decrease the friction of the metals , the lubrication also can keep the surfaces of the spherical roller bearing against corrosion , how to choose the proper lubrication , it’s very important work , let talk about it .

FAG 22208 Spherical roller bearing lubrication have so much brand and grade of grease , oils and more the other materials , so its very important to select a right method for lubrication , its according to the spherical roller bearing application's working condition , for example the speed or operating temperature , and the applications also affect the selection process like vibration and loads demand.
