NB

NB (Nippon Bearing Co., Ltd.) is a Japanese manufacturer of linear motion components, established in 1960 and headquartered in Niigata Prefecture. The company specializes in ball splines, linear guide rails, and slide bushings, with a product portfolio that includes the Alulin series of steel-reinforced aluminum guide rails and runner blocks, as well as stainless steel ball spline shafts and flanged nuts. NB components are used in applications requiring precise linear motion, such as industrial automation, packaging machinery, semiconductor manufacturing equipment, and medical devices. Key technical characteristics include minimum surface hardness ratings of 60 Rc on ball spline shafts, stainless steel construction for corrosion resistance, and aluminum guide rails with steel reinforcement for reduced weight without sacrificing rigidity. The Alulin series offers nominal rail sizes from 15 to 20, with overall lengths up to 4,000 mm, and runner blocks with steel rollers and aluminum carriages. NB ball spline nuts feature oil holes for lubrication and are constructed from carbon steel and resin. 3G Electric supplies NB linear motion components globally, including ball spline shafts in diameters from 6 mm to 23 mm and lengths from 150 mm to 750 mm, as well as flanged ball spline nuts with inside diameters of 10 mm. The Alulin series guide rails and runner blocks are available in standard sizes, with support for custom lengths and configurations. 3G Electric provides logistics support for NB products, ensuring availability for plant engineers, maintenance managers, and procurement specialists who require reliable linear motion components for new builds or retrofits. NB components are designed to meet JIS (Japanese Industrial Standards) and ISO specifications, with tolerances suitable for high-cycle automation environments. The ball spline shafts are ground to precise diameters and surface hardness, while the Alulin series offers a lightweight alternative to all-steel guide rails for applications where weight reduction is critical. 3G Electric stocks NB products in Indonesia and ships globally, with technical support available for selection and integration.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang NB dari 3G Electric.

What is the minimum surface hardness of NB ball spline shafts?

NB ball spline shafts, such as the SSP25S-450mm and SSP6S-150mm, have a minimum surface hardness of 60 Rc. This hardness rating ensures wear resistance and dimensional stability under load, making these shafts suitable for high-cycle linear motion applications. The hardness is achieved through heat treatment and grinding processes, and it applies to both stainless steel and carbon steel variants.

What materials are used in NB Alulin series guide rails and runner blocks?

NB Alulin series guide rails are constructed from steel-reinforced aluminum, combining the lightweight properties of aluminum with the strength of steel. The runner blocks, such as the GNS-1500, have aluminum carriages and steel rollers. This material combination reduces overall system weight while maintaining load capacity and rigidity, making it suitable for applications where inertia reduction is important.

What lubrication options are available for NB ball spline nuts?

NB flanged ball spline nuts, such as the SSPF 10, feature an oil hole for lubrication. This allows for periodic grease or oil injection to reduce friction and extend component life. The oil hole is positioned on the nut flange for easy access during maintenance. Proper lubrication is essential for achieving the rated load capacity and service life of the ball spline assembly.

What are the available shaft diameters and lengths for NB ball spline shafts?

NB ball spline shafts are available in diameters ranging from 6 mm to 23 mm, as seen in models like SSP6S-150mm (6 mm diameter) and SSP25S-450mm (23 mm diameter). Standard lengths range from 150 mm to 750 mm, with custom lengths possible through 3G Electric. The shafts are precision-ground to ensure smooth motion and consistent fit with matching nuts.

What is the nominal rail size range for NB Alulin series guide rails?

NB Alulin series guide rails are available in nominal rail sizes 15 and 20, as indicated by models like A20-760mm (size 20) and the GNS-1500 runner block (size 15). The size designation corresponds to the rail width and overall dimensions, with size 20 rails having a 20 mm width and 19 mm to 21.8 mm height, depending on length. These rails are designed for use with matching Alulin series runner blocks.
