NTN Spherical roller bearings

Feature

These bearings have an outer ring with a spherical track surface, and an inner ring that encloses two rows of barrel-shaped rolling elements.

Various types exist that differ by internal design, including bearings with a tapered bore inner caliber. The bearings are easily mounted on the shaft with an adapter or un-mounting sleeve, and are used in many industrial machines for their high load capacity. Potential troubles include one row bearing no load when axial load is large, calling for attention to usage conditions.
