China Crowned Separable Roller Follower Bearings Rnast6

Crowned separable roller follower bearings RNAST6
The Roller Follower is a compact bearing with a high-rigidity shaft and a built-in needle bearing. Most suitable as a guide roller for cam mechanisms and linear motion.
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.
1. 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.
2. NAST-R
This model is a spherical outer ring type of model NAST.
Since the circumference of the outer ring is spherically ground, it helps lighten a biased load (symbol R).
3. NAST-Z
This separable type of bearing system has a labyrinth seal consisting of a pair of side plates formed on both sides of the inner ring of model NAST. (Model number of the type attached with seals is NAST-ZZUU. )
4. NAST-ZZ
This model is a spherical outer ring type of model NAST-ZZ.
It easily corrects a distortion of the shaft center when the roller follower is installed.
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-ZZUUR. )
