ROTARY BALL SPLINE

SPB TYPE

The NB ROTARY BALL SPLINE SPB type integrates a spline outer cylinder and a rotational part with an angular contact structure to provide compactness, high-precision, high-rigidity, high-speed rotation mechanism capable of linear and rotational motion at the same time.

SPLINE SPB TYPE

Features

Compactness, high-precision, high-rigidity, high-speed linear and rotary motion.

Compact, high-precision, high-rigidity, high-speed rotation

The NB ROTARY BALL SPLINE SPB type integrates a spline outer casing and a rotating part with angular contact structure to provide compactness, high-precision, high-rigidity, high-speed rotation mechanism capable of linear and rotational motion at the same time.

Preload and rotational clearance

The preload of the linear motion part is also expressed in the rotational direction and can be selected from three types: standard, light (T1), and medium (T2) preload. The rotary section is properly adjusted by spacing.

Accuracy

The accuracy of the NB rotary ball spline SPB type is measured as shown in the figure.
