Tapered roller bearings with tapered inner and outer ring raceway, tapered roller are arranged in between. The projection line of all cone appearance are all in the same meet the bearing axis. This design makes spherical ball bearings is particularly suitable to accept composite (radial and axial load).
Axial load to large local crossed roller bearings is by the contact angle resolution; alpha angle is larger, the higher axial load ability. Angle by calculating coefficients of e to say; the bigger the E value, the contact angle the greater the applicability of reception, bearing axial load greater.
