SHAFT 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. ADVANTAGES Advanced Machining Technology Wide Selection of Shaft Types NB performs a wide variety of highly accurate machining processes to provide custom shafting from relatively simple machining, such as tapping and shaft stepping to the more demanding...

SHAFT CALCULATION OF DEFLECTION AND DEFLECTION ANGLE The following formulas are used to obtain the deflection and its angle of the shaft. Typical conditions are listed in Table F-3. Table F-3 Formulas for Calculating Deflection and Deflection Angle Table F-4 Solid Shaft The moment of inertia of area (I) is obtained using the following formulas: support method fixed 2 ┃ fixed support 3 ┃ support fixed 4 ┃ fixed support 5 ┃ support support 9 ┃ support fixed 10 ┃ fixed uniformly distributed load p δmax＝ uniformly distributed load p δmax＝ The values of the moment of inertia of area and C (=1/48 EI)...

Tolerances other than g6 are available upon request.

NB CENTER-LINED TAPPED SHAFT A larger diameter shaft can overcome problems in maintaining precision functionality when a high or unbalanced load is applied. A combination of the center-lined tapped shaft together with the SA type support rail is ideal in such cases. (see pages F-18,19) The center-lined tapped shaft is standardized to simplify shaft selection. part number structure example SNT 25 h5 × 576 part number structure example SNSB 25 × 576 length （L） SNT type outer diameter tolerance g6 when blank length （L） material SNB: SUJ2 SNSB: equivalent to SUS440C part number material: high-carbon...
