제품 상세 설명

STRUCTURE AND ADVANTAGES
The NB ROTARY BALL SPLINE SPB type combines a spline nut and a set of angular contact bearings in a compact, high accurate, and high-speed rotation-capable assembly, providing both linear and rotational motion at the same time.

Structure of SPB type

The amount of clearance and preload for the spline nut is expressed in terms of the clearance in the rotational direction.
Three levels of preload are available: standard, light( T1), and medium( T2).
The preload is properly adjusted by the spacer for the angular contact bearings.
