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.
