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.
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.
Structure of SPB type
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.
