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. ■ Outline of SLIDE GUIDE Five different types of slide guides, each with differing structures are available for your selection. ("SEBS-B type" is structurally the same as the SEB-B type, however all "-B" types use stainless steel, and thus for the sake of simplicity are specified as "SEBS-B type") Miniature Type >> 【SEBS-B Type】 　 　- 2-row,4-point contact / retainer built-in - This is an easy-to-install 2-row, 4-point contact structured type that keeps rails and block separate using a retainer. For moment resistant versions, wide block, long block and in addition a wide & long block version are all available. It is also possible to choose all stainless steel versions using stainless steel return caps. ▼　Lineup >> 【SEB-A Type】 　 　- 2-row,4-point contact / without retainer - This is an easy-to-install 2-row, 4-point contact structured type that keeps rails and block separate without a retainer. For moment resistant versions, wide block, long block and in addition a wide & long block version are all available. It is also possible to choose all stainless steel versions using stainless steel return caps. ▼　Lineup >> 【SER Type】　- crossroller - In addition to being extremely precise, this roller guide is minimally sized and employs a crossroller.

By using stainless steel for "SERS type" component parts, these products can also be used in specialized environments, such as vacuums. ▼　Lineup High-rigidty Type >> 【SGL Type】 - 4-row,2-point contact - Through use of 4-row, 2-point contact design and large ball elements, and a raceway with grooves machined close to that of the ball elements making larger load capacity and longer life possible. In addition, as ball elements are positioned to increase their self-aligning characteristics, the design provides absorption of dimensional error caused during installation. (Law Temperature Black Chrome Treatment comes as an option) ▼　Lineup >> 【SGW Type】 - 4-row,2-point contact - This type is highly moment-resistant and suited to single-rail applications, due to its low height and wide profile. Similar to the "SGL type", raceway grooves are machined to a radius close to that of the ball elements, meaning that the larger contact surface provides a high load capacity and longer life.

The NB's 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. Moreover, the newly developed [STUD ROLLER SYSTEM] makes possible the prevention of slippage from the roller. ■ The NB's SLIDE TABLE is a precision table equipped with a slide way. Its high-precision and lowfriction characteristics make it well suited for use in electronics automatic-assembly machines and optical measurement devices. ■ The NB's GONIO WAY is a curved motion bearing utilizing lowfriction, 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. ■ Outline of SLIDE WAY Two different types of SLIDE WAY are available for your selection. * The [STUD ROLLER] is planning to be standardized to all the SLIDE WAYS. >> 【NV Type】　-　STUD ROLLER SYSTEM　- [ NV type ] consist of precisely ground tracking bases and R-retainers with built-in studrollers.

NB's 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. ■ NB's POSITIONING TABLES are general purpose precision positioning tables that employ pulse motors and make high levels of speed and accuracy possible. For guidance, an NB slide way (NCT type), NB slide guide (NPT type, NBL type) and NB Slide unit (NSL type) are all built-in, and precision ball screws are used in the conveyance apparatus, so that assured precision is guaranteed from high speeds to low speeds. ■ Outline of ACTUATOR The "U" shaped guide rail design offers a high rigid structure resistant to bending. This structural feature allows for integrated framework of machinery or equipment and may be one-end supported. Additionally, the slide block contains 4 ball circuits which delivers high load capacity, high accuracy and high rigidity. >> 【BG Type】　 ■ Five different types of actuators( [BG20], [BG26],[BG33],[BG46],[BG55]),each with differing the size are available for your selection.Moreover, Four different types( [-A], [-B],[-C],[-D]),each with differing the length of the block are available. ▼　Lineup ■ Outline of POSITIONING TABLE From areas such as mechatronics to a wide array of other applications, this product employs low height and high precision specifications, so that it is able to handle conditions where space height is restricted. In addition, all shape dimensions are serialized, meaning that when using for X-Y the stroke combination of your choice is possible. >> 【NCT Type】　- SLIDE WAY [SV Type] built-in - ■ stroke / 50mm～300mm ■ guidance / SLIDE WAY [SV Type] ■ load-proof / middle ■ motor type / 5-axis stepping motor ?AC servo motor ■ features / high accurcy ?high rigidity ?low height ▼　Lineup >> 【NBL Type】　- SLIDE GUIDE [SEB Type] built-in - ■ stroke / 50mm～800mm ■ guidance / SLIDE GUIDE [SEB Type] ■ load-proof / middle ■ motor type / 5-axis stepping motor ?AC servo motor ■ features / light weight ?high accurcy ?long stroke ?bellows available ▼　Lineup >> 【NPT Type】　- SLIDE GUIDE [SGL-H Type] built-in - ■ stroke / 300mm～1,000mm ■ guidance / SLIDE GUIDE [SGL-H Type] ■ load-proof / heavy ■ motor type / 5-axis stepping motor ?AC servo motor ■ features / high accurcy ?high rigidity ?long stroke ?bellows available ▼　Lineup >> 【NSL Type】　- SLIDE UNIT [CD Type] built-in - ■ stroke / 50mm～800mm ■ guidance / SLIDE GUIDE [SGL-H Type] ■ load-proof / middle ■ motor type / 5-axis stepping motor ?AC servo motor ■ features / light weight ?low cost ?long stroke ?bellows available ▼　Lineup ■ NB ACTUATOR Lineup Please refer to the PDF catalog on the Downloads page for more detailed information. * Click each name or image, Part number structure can be checked.
