Are any of your applications

this complex?

Then your application requires positioning, linear and rotary motion as well as combined spiral motion.

All these requirements are met by Ball Screw Splines.

NB's two types of Ball Screw Splines are the SPBR and the SPBF. The SPBR type has a Rotary Ball Screw nut and Rotary Ball Spline nut. The Rotary Ball Screw nut is an integration of ball screw nut and angular contact bearings. Rotary Ball Spline nut is an integration of ball spline nut and angular contact bearings. The SPBF type has a Rotary Ball Screw nut and a Ball Spline nut.

A single axis of the NB Ball Screw Spline can provide positioning, linear and rotary motion as well as combined spiral motion. The typical applications are SCARA robot, assembly machine, loader, etc.

But, for less complex linear motion, NB manufactures

3 primary series of linear bushings:

1. SW/SM/KB series:

SW/SM/KB series are the standardized linear bushings with closed, open and adjustable type with single and double wide in Inch, Asian metric and European Metric sizes.

2. Pillow block type series:

A wide range of pillow block type housings are available for NB linear bushings, including both resin and machined steel components. When properly paired, you can count on NB linear bushings and pillow block assemblies to deliver high-accuracy, low-cost performance.

3. FIT series:

FIT series products combine an NB linear bushing bearing and precision-machined shaft to deliver smooth, highly accurate performance.

NB linear bushings are available in standard and flanged design types. For a complete list of available products — along with dimensions, tolerances and other detailed specifications —

Why is the BG Ball Screw Actuator

called a linear stage?

Because all linear stages consist of a platform and a base, joined by some form of guide or linear bearing in such a way that the platform is restricted to linear motion with respect to the base.

But NB's Ball Screw Actuator presents a compact single axis actuator with a unique “U” shaped integrated slide guide and ball screw. The BG Actuator’s highly rigid structure may be one-end supported. The 4 ball circuits contained in its slide block deliver high load capacity, accuracy and rigidity. 

3D / 2D CAD Data PARTcommunity

3D / 2D CAD data [PARTcommunity] is available for selected products.

[PARTcommunity] has functions to view 3D / 2D drawings by specifying values and to insert the drawing into the CAD screen.

Need a curved linear bearing?

• The NB RVF Gonio sets the standard for slide ways designed for minute curved motion.
• No other curved radius slide way has both hardened and ground raceways. They last longer and afford smoother, accurate movement.
• Mounting ease is ensured by the NB RVF Gonio’s flat mounting surface that speeds assembly.
• The RVF Gonio Way is used mainly in optical equipment and measuring devices.
