High Clearance Spherical Roller Bearing 22222 E1 C3

High clearance spherical roller bearing 22222 E1.C3  

roller bearings are inherently self-aligning and very robust. They have two rows of rollers which make the bearings able to carry heavy loads. The TVB spherical roller bearings mainly includes CC, CA, CAE, MB and E type. TVB can provide a wide range of sizes of several ISO Dimension Series and also includes special designs, for example, for vibrating screens and other applications. Special bearings can also be customized as required based on the standard bearings.

1,Dimension

Overall dimension of bearing listed in beaing table accords to ISO015-1981.

2,Angular alignment tolerance

Self-aligning roller bearing is designed in such a way that it is self-aligning.That means that bearing can adjust itself and angular alignment tolerance between outer rings.Under normal load and working condition and inner ring rotates,the unsymmetrical value listed in below table is allowed.Achieving completely specifide value is subject to design and seal type of configured bearing.

3,Tolerance

The self-anligning roller bearing with cylindrical bore or tapered core is of common tolerance level .

4,Internal clearance

 According to the WQK standard,self-aligning roller bearing is of common tolerance level in internal clearance in its radial direction.Almost all bearings can be supplied at C3 clearance,or even higher level C4 clearance.Bearings with dimension less than common level:C2 clearance can also be supplide.Please consult first to check supply status for bearing with non-standard radial clearance (includingC5).These clearance values are used for zero load testing and shaft,which remains uninstalled.

Besides CA type, we can provide CC and MB structure for special clients.

 5.Lubrication

   Open spherical roller bearings can be lubricated with oil or grease.

    Most spherical roller bearings have a circumferential groove and three lubrication holes in the outer ring for lubrication. In bearings of series 239 with an outside diameter < 320 mm, this is indicated by the suffix S.

 Bearings of series 213 with a bore diameter up to 35 mm do not have a lubrication groove and lubrication hole.

    If shafts with a vertical axis are supported using spherical roller bearings, particular attention must be paid to ensuring the reliable provision of lubricant. In such cases, oil lubrication should be used.

Operating temperature

   Spherical roller bearings are dimensionally stable up to +200 °   C. Bearings with metal cages can be used at operating temperatures from -30 °C to +200 °C.

  Bearings with cages made from glass fibre reinforced polyamide are suitable up to +120 °C.

 Cages

   The standard cages for spherical roller bearings are shown in the table and link.

    Spherical roller bearings with a rigid central rib on the inner ring (design without suffix E1) have solid cages or sheet metal cages made from brass. Bearings with sheet metal cages do not have a cage suffix.

    In bearings with the suffix MB, the solid brass cages are guided on the inner ring while, in bearings with the suffix MA, they are guided on the outer ring, Figure 2. Bearings with the suffix M have a roller-guided solid brass cage, Figure 2.

  X-life bearings

   Bearings of series 213..-E1, 222..-E1, 223..-E1, 240..-E1 and 241..-E1 without a cage suffix have sheet steel cages. The two cage halves are retained by a guidance ring in the outer or inner ring, Figure 1.

    In bearings of series 223..-E1, 240..-E1 and 241..-E1, all sheet steel cages have special protection against wear by means of surface hardening or coating.

   The other bearings of E1 design have solid cages made from ­glass fibre reinforced polyamide 66 or solid brass cages (suffix TVPB or M), Figure 2.

   Check the chemical resistance of polyamide to synthetic greases and lubricants with EP additives.

   Aged oil and additives in the oil can impair the operating life of plastic cages at high temperatures. 

   The oil change intervals must be observed
