Sealing ring self-aligning roller bearing generally refers to the installation of sealing rings on both end faces of the bearing. The design of the bearing is mainly based on the C-shaped structure of the double row self-aligning roller bearing, with the outer ring being a concave spherical raceway and the inner ring being two concave arc-shaped spherical raceways without outer and outer retaining edges. There is a set of symmetrical spherical drum shaped rollers, stamped with C-shaped steel cage, and the window hole is pressed and sloped to lock the roller arc surface. It is equipped with a powder metallurgy intermediate retaining ring, and the middle part of the outer ring is processed with three lubricating oil grooves and oil holes. Due to the need to install sealing rings, the width of BS2-22 and BS2-23 series sealed bearings should be appropriately widened, and the external dimensions of other bearings are completely the same. The outer ring has a sealing groove, and the edge of the inner ring raceway has a slope. The outer diameter of the sealing ring is fixed on the outer ring, and the inner lip forms a contact seal with the inner ring slope. The main function of this bearing is similar to that of an open type self-aligning roller bearing, but it is more suitable for situations with harsh working conditions and difficult maintenance.

Sealed self-aligning roller bearings are divided into cylindrical holes and tapered holes (suffix code K, taper 1:12, suffix code K30, taper 1:30).The sealing ring is generally made of nitrile rubber with a suffix of 2CS. When paired with high-temperature bearings, fluororubber with a suffix of 2CS2 is used.

The sealed bearing has been injected with extreme pressure lubricating grease. Before installing the sealed bearing, it must not be cleaned or heated beyond 80 ℃.Sealed bearings allow for an angle error of less than 0.5 degrees between the bearing and the bearing seat, which does not affect the sealing function within this reference value.
