Product Description

Bearing of this type has two rows of spherical rollers between the sphered raceway in the outer ring and two inner rings raceways inclined at an angle to the bearing axis.According to the difference of the bearing internal structure, there are five types of cages:CA,MA,CC,E and CTN1.Due to the arc center of the raceways in the ourter ring and the bearing center are in the same direction, as a result, shaft flexing and misalignment of the bearing seats are compensated. Bearings of this type  can support axial forces in both directions and high radial forces. They are designed for very high load carrying capacity. Bearings with a tapered bore are also available with an adapter sleeve, locknut and tab washer or with a withdrawal sleeve.When shaft bends by force which causes the inclined between the center of inner ring and the center of outer ring,if the inclined degree not exceed 1-2.5,the bearing can work normally.
This series is available in tapered bore - suffix "K" (taper 1:12).
1) Suffix "W/33" - lubrication groove and holes in outer ring.
2) C/3, C/4, and C/5 internal clearances are also available

Application:Rolling mills,crushers,construction machinery,papermaking machinery,blowers,gearboxes,vibrating screens,...etc
