Description: Spherical roller bearings has two columns of roller, mainly endure radial load and also withstand any direction of axial load at the same time. This kind of bearing own a high capacity of radial load especially suitable for heavy load or vibration , but can not bear pure axial load . The outer ring groove of this bearing is spherical, so it's favorable in regulating the heart. Spherical roller bearings and self-aligning ball bearing are the same at the structure theory and character, so they can substitute each other in the permission of load capacity and speed limit.

Self-aligning Roller Bearings are bearings with drum-shape rollers between the inner ring of the two roller paths and outward ring with ball-shaped roller path.? As curvature centre of the outward roller surface is in line with the centre of the bearing, it has same aligning function as automatic aligning ball bearing. When axis or out covering of the bearing were crooked, they could adjust themselves, instead of creating extra burden for the bearing. It could bear radial load as well as axial load from two directions. Radial load is bigger and applicable to heavy-load,impact load. Bearings with cone-shapes inner rings or diameters could be assemble directly or could be assembled on the cylinder axis, using fixing sleeves or disassembling buckets. The cages are made of stamping steel or polyamide or copper alloy.

Self-aligning Roller Bearings could bear radial burden as well as axial burden. The rolling path of the outer ring is ball-shaped, thus the bearing is with function of self aligning and could also work when declination of the inner-ring centre and outer-ring center is no more than 1° -2.5°.

Spherical roller bearings are divided into symmetrical spherical rollers and non-symmetrically spherical rollers according to the roller section shape.

An early product of asymmetrical spherical roller bearings, current focus is maintenance service. New design master is rarely choose symmetrical spherical roller bearings. Improved design and parameters optimization of internal structure thoroughly, it can withstand larger axial load compared with the earlier production of spherical roller bearings. It can meet the demands of high speed since the lower operating temperature of the bearings.

According to the different bearing cages and inner ring with flanges, this type of bearings can be divided into type-C and type-CA. Characteristics of type-C bearing are without flanges of inner ring and general use of steel stamping cage. The features of type-CA are flanges on both sides of the inner ring and solid cage.

To improve the lubrication , we can provide self-aligning bearings with endless oil groove in the outer ring and three oil holes (with code "/W33"). Under users' requirements, we can also supply aligning roller bearings with inner ring hole. To facilitate customer handling and replacement, aligning roller bearings with taper bore, the taper is 1:12 (with rear code "K"). In order to meet the special requirements of users, we can also provide in the bearing with taper hole of 1:30, then the rear code is K30. Tapered bearings can be mounted directly on tapered shaft seating by lock nut, or using adapter or withdrawal sleeves on a cylindrical bearing installation. In order to ensure that the centrifugal effect the bearings in high speed to prevent harmful slip between the raceways and the rollers, the bearings should bear certain minimum radial load.
