NB products combine compact size, high-load capacity, flexible mounting options and high resistance to demanding environments.
Product Lineup
Slide Guides (Linear Guide)
The SLIDE GUIDE is a high-precision and high-rigidity linear guide designed to utilize the motion of rolling elements. They have numerous advantageous characteristics including low friction, no stick/slip, and smooth linear motion even under high load conditions. Since they can maintain their high-efficiency and high-functionality characteristics for an extended period of time, they meet a wide range of needs, from general industrial to precision machinery.

Ball Spline, Stroke Ball Spline
The BALL SPLINE is a linear motion mechanism utilizing the recirculating motion of ball elements. It can be used in a wide variety of applications including robotics and transport type equipment.
- Ball Spline SSP/SSPM
- Rotary Ball Spline SPR
- Rotary Ball Spline SPB
- Stroke Ball Spline
- Ball Screw Splines
Slide Ways (Cross Roller Guide)
The SLIDE WAY is a non-recirculating crossed roller slide way utilizing precision rollers. It is used primarily in optical and measurement equipment where high precision movement is required. Precision rollers are used as rotating elements. Since they do not recirculate, there is less frictional resistance fluctuation. Additionally, there is little or no difference between the static and dynamic frictional resistances.

- Miniature Ball Slide SYBS
- Curved Cross Roller Guides – Gonio Way
Slide Bushes (Linear Bushings)
The NB SLIDE BUSH is a Linear Ball Bushing utilizing the recirculating motion of ball elements. This consists of the outer cylinder and a ball retainer that guide the circulation of the ball elements, resulting in smooth linear motion. Moreover, SLIDE BUSH is fully compatible with a variety of Linear Shaft types. Pillow Block Units and Flanged Bushings provide excellent installation environments.

Linear Stages (Actuator)
The NB ACTUATOR is a compact single axis linear actuator which integrates a slide guide and precision ball screw. BG type offers compact dimensions and 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.
Slide Screws
The SLIDE SCREW converts rotational motion into linear motion by utilizing the friction between radial ball bearings and a shaft. This simple mechanism eases maintenance and installation work. The SLIDE SCREW is most commonly used as transport devices in many types of machines, and is not intended for accurate positioning requirements.
Shafts & Spindles
The NB SHAFT is a linear shafting that can be used in a wide range of applications as mechanical components from straight shafts to the SPINDLE shafts. NB’s expertise in machining and heat-treatment turns into manufacturing spindle shafts, roll shafts, and general machinery shafts for rotational motion. NB’s high accuracy technology answers various shaft machining requirements.
Stroke Bushes
The STROKE BUSH is a linear and rotational motion mechanism utilizing the rotational motion of ball elements between an outer cylinder and a shaft. It is compact and can withstand high loading. The retainer is made of a light metal alloy with high wear resistance. Smooth motion is achieved under high-speed and highacceleration conditions. Although the linear motion is limited to a specific stroke length, the combined rotation and stroke motion is achieved with very little frictional resistance. The NB STROKE BUSH can be conveniently used in a variety of applications.
