NART-VR

Full Roller Type

Skip to the beginning of the images gallery

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.
