The NB SLIDE GUIDE are high-precision and high-rigidity linear bearings 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.
The NB BALL SPLINE is a linear motion mechanism utilizing the rotational motion of ball elements. It can be used in a wide variety of applications including robotics and transport type equipment.
The NB ROTARY BALL SPLINE can be used for both rotational motion and linear motion. It can be used in scalar robots, the vertical shaft of assembly equipment, and tool changers and loaders.
The NB SLIDE BUSH is a linear motion mechanism utilizing the rotational 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, NB SLIDE BUSH is fully compatible with a variety of shaft types.
Used in a number of industrial fields, such as transportation equipment, food processing equipment and semiconductor equipment, NB SLIDE BUSH have been endorsed by many of our clients as “standard parts for linear motion”.
The NB TOPBALL is a linear motion mechanism utilizing the rotational motion of ball elements. NB’s self-aligning TOPBALL can be designed into many different applications such as factory automated equipment, machine tools, industrial machines, electrical quipment, optical and measuring instruments.
STROKE BUSH・SLIDE ROTARY BUSH
The NB 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.
The NB SHAFT can be used in a wide range of applications as a mechanical component from straight shaft to SPINDLE shaft. NB’s expertise in machining and heat-treatment turns into manufacturing spindle shaft, roll shaft, and general machinery shaft for rotational motion. NB’s high accuracy technology answers various shaft machining requirements.
SLIDE WAY・GONIO WAY
The NB SLIDE WAY is a non-recirculating linear motion bearing utilizing precision rollers. It is used primarily in optical and measurement equipment where high precision movement is required.Precision rollers are used as the rotating element. 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.
The NB GONIO WAY is a curved motion bearing utilizing low friction, non-recirculating, precision cross-rollers. It is used when there is a need to change the gradient or obtain an accurate gradient angle without changing the center of rotation in high-precision optical and measurement equipment.
NB ACTUATOR is a compact single axis 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.
The NB 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.
