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.
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”.
