Spherical roller bearings are capable of withstanding the most arduous environments and operating conditions. Spherical roller bearings are self-aligning in the outer ring based upon the curvature of the raceway and rolling element.
With the spherical roller bearings' self-aligning characteristics, deviations in shaft misalignment can be accepted more easily. Low to medium speed applications are optimal when integrating the spherical roller bearing into your product solution.
Common models of spherical roller bearings available through Ritbearing include the 21300 Series, 22200 Series, 22300 Series, 23000 Series, 23200 Series, 23900 Series, 24000 Series, 24100 Series.
The inner ring of spherical roller bearings have two raceways, outer raceway is a part of a sphere, whose curvature center is on the axis of bearings. This type of bearings possesses self-aligning performance, allowing the misalignment of shaft, and can also be used under certain permanent misalignment.
These bearings are able to carry higher radial loads, as well as certain axial loads, but can’t be used to carry pure axial loads. The osculation between rollers and raceways is high, and friction is higher than cylindrical roller bearings. Therefore, the limiting speed is lower.
This type of bearings is especially suitable to the heavy or vibrating load applications.
The type 20000C bearings have symmetrical rollers and pressed steel cages, no rib on inner ring, rollers are longer, load carrying capacity is high, and rollers are guided by a floating guide ring.
The type 20000CC bearings are the modified type to type 20000C, the friction between rollers and raceway is decreased, load carrying capacity is enhanced.
The type 20000CA bearings adopt symmetrical spherical rollers and machined solid cages, they have floating guide ring and integral ribs on inner rings.
The type 20000TN1 bearings use symmetrical rollers and nylon molded cages, no integral ribs and floating guide ring on inner ring, the cages are guided by rollers.
The type 20000CC, 20000CA and 20000TN1 bearings are developed in recent years and their internal design are optimized, should give priority to be used.
Spherical roller bearings are primarily used in the applications,
such as rolling mills, paper-making, power transmitting equipments and ship mechanics, gearbox, vibratory,Metallurgical
