The NB Linear 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. Advanced Machining Technology NB performs a wide variety of highly accurate machining processes to provide the custom shafting from relatively simple machining, such as tapping and shaft stepping, to the highspeed rotating shafts and spindles. NB can also answer the special grinding and bore machining requirements. Special Requirements Based on the customer drawings and specifications NB will answer the customer requirements in material (SCM, SKS etc.), heat-treatment, surface treatment, etc. Excellent Wear Resistance Most commonly used materials are high-carbon chromium bearing steel (SUJ2 or equivalent) and martensite stainless steel (SUS440C or equivalent). NB’s advanced heat-treatment technology gives these materials an excellent wear resistance by quenching and tempering to achieve a uniform hardened layer in the circumferential and axial directions. The cross-sectional picture below shows the hardened layer-depth of the NB shaft. Shaft Supporter and Shaft Support Rail These components ease the shaft installation and help save the design/assembling time. Surface Roughness Precision grinding results in a surface roughness of less than Ra 0.4 FIT Series FIT series is a set of a linear bushing and a linear shafting. By precise shaft-grinding, FIT series achieves the best-fit clearance adjustment for a smooth.
