Models
Model NAST
A separable type of bearing that combines a thick-wall outer ring, an inner ring and needle rollers equipped with a precision cage. Since the structure is simple, it allows high accuracy to be achieved at low cost.
Model RNAST
A bearing that combines a thick-wall outer ring, an inner ring and needle rollers equipped with a precision cage.
Model NART
This model is a non-separable type of bearing system whose inner ring is fixed to the side plates. Since the outer ring is spherically machined, it helps reduce a biased load.
