BALL SCREW SPLINE SPBR type, SPBF type

Product catalog summary

Overview
The document introduces the NB Ball Screw Spline, which integrates positioning, linear, and rotary motion capabilities into a single axis. The SPBR and SPBF types are highlighted, each offering unique configurations for various applications such as SCARA robots and assembly machines.

Specifications
The Ball Screw Spline consists of a high-accuracy, high-rigidity Ball Screw nut and Ball Spline nut attached to a spline shaft with screw and spline grooves. The SPBR type includes a Rotary Ball Screw nut and Rotary Ball Spline nut, while the SPBF type features a Rotary Ball Screw nut and a Ball Spline nut.

Accuracy and Preload
Accuracy is measured at specific points as shown in Figure 2. The preload for the ball screw nut, spline nut, and angular contact bearings is factory-adjusted. Users are advised not to adjust the spacer or remove the Rotary Ball Screw nut from the shaft.

Handling Precautions
Users should use a pulley centering supporter when attaching the pulley to the return-cap. The document advises against adjusting the spacer or removing the Rotary Ball Screw nut from the shaft due to the absence of a ball-retainer.

Motion Patterns
The SPBR type can handle linear, rotational, and spiral motion, while the SPBF type is designed for linear motion. Detailed motion patterns and calculations for travel distance and rotations are provided.

Tables and Figures
Several tables provide detailed specifications, including radial runout, tolerance levels, and preload conditions. Figures illustrate the structure of the SPBR and SPBF types, as well as accuracy measurement points.

Contact details for NB Corporation's offices in the Netherlands, USA, and Japan are provided for further inquiries.
