Actuator High Accuracy Single Axis Actuator BG Type

NB's BG Type is a compact single axis actuator which integrates a Slide Guide and Precision Ball Screw. BG Type offers compact dimensions, which outperforms conventional positioning tables. This is made possible by a unique "U" shaped Guide Rail and Slide Block which provides multiple functions of a Guide Block and a Ball Screw Nut combined into a single unit. The "U" shaped Guide Rail design offers a high rigid structure resistant to bending. This structural feature allows for integrated frameworks of machinery or equipment. Additionally, the Slide Block contains 4 ball circuits which delivers high load capacity, high accuracy and high rigidity.

Slide Screw  Rectilinear Motion Enabled With A Round Shaft

The NB Slide Screw is a unique drive unit which makes efficient use of friction to convert rotary motion to linear motion. This unit is a very simple mechanism containing only radial bearings in contact with a shaft, providing ease of maintenance. Even if an accident occurs, this unit slips on the shaft, stopping itself to prevent further damage. The unit is applicable to a wide variety of devices by fully utilizing its features, although while accurate positioning would require an extra control.

Slide Way

Excellent Accuracy Precise, Rigid, and Lowest Noise

The highly precise and rigid NB Slide Way incorporates cylindrical rollers in two 90 degrees V-grooved rails. Designed for advanced technological applications, the Slide Way can bear loads and moments from all directions while maintaining extreme accuracy. The lowest frictional resistance and noise are achieved with "super precision" cylindrical rollers and "high accuracy" raceway surfaces.

Ball Spline Stroke Ball Spline.  Eliminates Backlash, Reduces Friction

The NB Ball Spline is designed for mechanical applications which require both linear motion and torque transmission. The rolling contact of the balls eliminates backlash and reduces friction, helping you to achieve super precision and reliability.

The spline shaft facilitates additional machining and high accuracy because of a round shaft shape. Since the spline shaft is also machined by cylindrical grinding, it has a high sealing performance and a well-balanced structure that reduces the vibration and noise during rotary motion. Moreover, it has great geometrical moment of inertia and high rigidity. This enables a long-term, high precision linear motion.

Slide Guide  Compact Design, Precise Action

SEB Series / SER Series

The NB SEB/SER Miniature Guide are engineered to be compact and light weight to ensure precise linear operation at high speeds. The SEB Slide Guide uses precision-machined steel balls as rolling elements promoting exceptionally low resistance with smooth, stable operation at low cost. Likewise, the SER Slide Guide uses precision-machined cylindrical rollers, ensuring high rigidity and high load capacity with low noise.

Stroke Bush

While the NB stroke bush has a limited rectilinear traveling stroke, it works with minimal wear resistance and enables smooth linear/rotary complex motion. It can therefore be used with a variety of devices.

The NB stroke bush is designed to allow the ball bearings to rotate smoothly. The finely ground outer case contains a retainer which forms a staggered arrangement of the steel balls in machined holes on its inner surface. Each ball in the retainer may rotate smoothly in its individual hole while the outer case moves in a rotary and/or rectilinear reciprocating motion.

NB's long standing technological leadership in Slide Way product, has brought about a new product to address radius movement. NB's GONIO WAY (RV type) is a non re-circulating crossed roller bearing providing low friction radius movement. The RV type is ideal for applications where sweeping movement or precise angular positioning is required without changing rotation center, such as in optical equipment and measuring devices.

Slide Shaft Optimum Performance Greater Accuracy

The NB Slide Shaft was developed to achieve greater accuracy in roundness, cylindricity, surface finishing, and linear travel. Heat treated in both axial and radial directions, NB Slide Shaft come in both high-carbon chromium bearing steel or Martensite stainless steel for maximum performance quality. In addition, our precision machining capabilities offer you a variety of specially engineered custom shafts, such as spindle and roll shafts, to meet your special requirement.

Slide Rotary Bush

This NB Slide Rotary Bush is designed to enable perfect, rectilinear/rotary complex motion. It offers considerable space-saving compared to conventional combinations of rectilinear and rotary bearings.

The Slide Rotary Bush therefore requires less installation space.

RotaryBall Spline

Number of parts can be cut down to half. This unity feature of conventional spline and rotary function dramatically contribute to eliminate parts used in your systems, and thence, accumulating minor errors that often seen due to installation process can be diminished as well.

Compact and Light weight. Cross-rollers are used for its rotary element in outer body of ball spline, so it is much lighter in weight and more compact in appearance. Cost for installation and additional matching can be greatly saved.

Rigid Structure. With NB's Rotary Ball Spline, feature of cross-roller and ball spline, of which has four ball circuits is maximized and is enhanced its rigidity notwithstanding its compact appearance.

Slide Unit

Fits Quick Into Your Design

Ease of assembly and replacement. NB Slide Unit is assembled by a Slide Bush in an aluminum or cast-iron housing and securing the Slide Bush with a snap ring. Slide Unit allows the Slide Bush to perform smooth motion easily with high precision and low frictional resistance. Since these Slide Units are made mainly of aluminum, providing high corrosion resistance.

Topball Products

High Performance, High Load and Self-Aligning

TOPBALL is NB's premier Slide Bush, offering up to 27 times the normal travel life of a conventional slide bush. Our uniquely produced load plates incorporate ground raceway surface which provides a circular arch contact to ball resulting in greater dispersion of loads for up to triple the normal load capacities. TOPBALL Slide Products are fully interchangeable with conventional linear bushing and feature self-alignment capabilities and NB's unique floating wiper seal. Smooth running, low friction operation, combined with longer life and reduced maintenance costs, make TOPBALL Slide Products the popular choice.
