Based on model NART-R, this model is a full-roller bearing suitable for locations where a heavy load is applied in low speed operation.
Since the circumference of the outer ring is spherically ground, it helps lighten a biased load (symbol R). (Model number of the type attached with seals is NAST-VUUR.)
