Spherical Roller Bearings
●Spherical roller bearings have good self-aligning ability and can perform during the shaft deflection under load or the shaft misalignment in mounting.
●This type of bearings has heavy load carrying capacity and anti-impact ability.
●In addition to radial loads, they can also carry axial loads in two directions.
●Vista mainly offers 22xxx、23xxx、24xxx series、wide inner ring Series spherical roller bearings. ●The type with lubricating oil hole in the inner ring can also be supplied.

Designs and Structures:
●CTN1: Nylon retainer
●C: Stamped steel retainer and strengthened symmetric rollers; offers considerably higher load ratings than conventional designs for a broad range of applications and long service life.
●CA: Alternative design of C design; Precision-machined one-piece brass retainer and strengthened symmetric rollers; used to exchange with C design, especially for large size.
●MB: Two-piece precision-machined brass retainer and strengthened symmetric rollers; equivalent to C design in load capacity.
●CC: steel cage, replace traditionalbrass cage
●E: Third generation design.
●The bearing contact is completely optimized and has improved stress distribution; offer much longer service life than normal designs.

Variations of exterior shape of inner & outer ring:
●K: tapered bore with taper of 1:12.
●N: locking groove on the outside ring.
●K30: tapered bore with taper of 1:30.
●W33: There are lubricating groove and three lubricating holes on the outside ring for fitting together with the body structure so as to realize the bearing lubrication from outside.

Clearance:
●/C2: less than nominal clearance
●/C0: nominal clearance, omitted in designation
●/C3: larger clearance than C0
●/C4: larger clearance than C3
●/C5: larger clearance than C4

Working temperature
●/S0: Working temperature can reach 150°C
●/S1: Working temperature can reach 200°C
●/S2: Working temperature can reach 250°C
●/S3: Working temperature can reach 300°C
