Double row cylindrical roller bearings are divided into bearings with cylindrical bore and tapered bore (add K behind bearing type). This type of roller bearings have compact structure, good rigidity, heavy load carrying capacity, and little distortion under loads. Because of their second row of rollers, double row cylindrical roller bearings are suitable for heavy radial loads. Double row cylindrical roller bearings are applicable for the machine tool spindle. Tapered inner bore could fine adjust clearance, simplify positioning fixture and be convenient to mount and dismount.
Depending on the existence of ribs on their rings, double row cylindrical roller bearings are classified into NN, NNU types.
Type NN double row cylindrical roller bearings have two integral flanges on the inner ring, a flangeless outer ring and a center flange in the middle. Double-row cylindrical roller bearings permit axial displacement in double directions of the housing relative to the shaft.
Type NNU double row cylindrical roller bearings have two integral flanges on the outer ring, a non-contacting inner ring and a center flange in the middle. Double row cylindrical roller bearings permit axial displacement in double directions of the housing relative to the shaft. Therefore, this type of bearing is suitable to be used as non-locating bearings.

Spherical roller bearings have two roller is mainly exposed to the diameter of a load, but also can withstand the axial load any direction. High radial load capacity, especially suitable for the work overload or vibration loads, but can not afford pure axial load. Kind of bearing outer ring raceway is spherical, so the good performance of aligning, can compensate concentricity error. Spherical roller bearings have two rows of symmetrical spherical roller, a common spherical outer raceway, inner ring raceway two bearing axis is tilted at an angle, aligning performance, when the axis of the force bearings can still be used normally when curved or install a different mind-mind with the bearing dimension series generally permissible aligning angle is 1 to 2.5 degrees, the load bearing capacity of the type, in addition to radial loads the outer bearing can withstand two-way axial load, with good impact resistance, in general, self-aligning roller bearings that allow the work of low speed.

Spherical Roller Bearing Part No.: 23226MBC3W33 Inner Ring: 130.000mm Outer Ring: 230.000mm Width: 80.000mm Chamfer: 3 Basic Dynamic Load Rating: 725KN Basic Static Load Rating: 1160KN Limited Speed (rpm): 1404(grease)/1904(oil) Gross Weight: 15.9kg Brass Cage Spherical roller bearing consists of an outer ring with spherical raceway and an inner ring with double-raceway, one or two cages, and one group of spherical rollers. Due to the center of spherical raceway of outer ring which is coinciding with the center of bearing, this makes it have a self-aligning capability. If there is a deflection of the shaft or housing or misalignment of their axes, it is automatically corrected the excessive force which is not applied to bearings. Spherical roller bearing has a high load carrying capacity for radial load and axial load in two directions. Spherical roller bearing is especially suitable for carrying heavy loads and impact loads, but this type of bearing permits a lower limiting speed. The permissible aligning angle of the spherical roller bearing working in normal conditions is 1°~2.5°. If bearings of this type have seals, then this function would be reduced. Spherical roller bearings are widely used in Steel Industry, Mining & Construction, Papermaking Machinery, Wind Turbines, Gearboxes, Electric Motors, Pumps & Compressors and Injection Molding Machines, etc. Multiple cage designs are available. Spherical roller bearings with hardened steel cages deliver greater fatigue strength, increased wear-resistance and tougher protection against shock and acceleration. Spherical roller bearings with brass cages provide extra strength and durability in the most unrelenting conditions, including extreme shock and vibration, high acceleration forces and minimal lubrication. Spherical roller bearings are available with a cylindrical bore for cylindrical type mounting, a tapered bore for tapered type mounting. To order tapered bore spherical roller bearing, add the suffix K� ( 1:12 ) or K30� ( 1:30 ) to bearing number (e.g., 23152K, 24172CAK30). An oil groove and holes are provided in the outer ring to supply lubricant and the bearing numbers are suffixed ?W33�.
