Spherical ball bearings have character of self-aligning because the center of its raceway profile right falls on the centurial line of its bore diameter. Even the shaft is bending slightly or the house is inclining slightly, these errors of alignments can not make the center of its raceway profile leave the center line of its bore diameter. It can accommodate mainly radial load and little axial load. Compared with the same size spherical rolling bearings, it has lower load capacity and faster speed.
Spherical Roller Bearings can endure big radial load and some axial load. Its outer race is spherical shape, so it has character of self-aligning. While the comparative inline degree between centurial line of the inner circle and the outer circle not more than 1-2.5, it can work normally.
They suit heavy load and impact load, and are widely used in the fields such as metallurgy, mining, petroleum, paper making, cement and sugar squeezing
These bearings are most used on the support shaft which are easy to bend when loaded and the parts whose support stand hole can not keep strict same axis degree, while the comparative inline degree between centurial line of the inner circle and the outer circle should be no more than three.
