21312C/W33 Spherical Roller Bearings have two rows of spherical rollers, the outer ring has a common concave spherical raceway, the inner ring has two concave raceways that are inclined at an angle to the bearing axis, the curvature center of the outer ring raceway is the same as the bearing center.
Spherical roller bearings are self-aligning and are not affected by misalignment of the shaft and bearing box or deflection of the shaft, and can compensate for the resulting concentricity errors. In addition to bearing radial load, this type of bearing can also bear two-way axial load and its combined load. It has a large bearing capacity and good vibration and impact resistance.
All the bearings we are offering are direct factory price, fast delivery, perfect quality. For more bearings, please feel free to mail us at sales@partsservicesupply.com, or contact us by Wechat or Whatsapp at +8618062246726.
