How to calculate shafting bar weight

Shafting bar weight per metre = D² × 0.006165 (D = diameter in mm, result in kg/m), using the density of steel, 7,850 kg/m³.

• 20 mm: 20 × 20 × 0.006165 = 2.47 kg/m, or 14.8 kg per 6 m
• 50 mm: 50 × 50 × 0.006165 = 15.41 kg/m, or 92.5 kg per 6 m
• 100 mm: 100 × 100 × 0.006165 = 61.65 kg/m, or 369.9 kg per 6 m

Shafting bar vs MS round bar

Both are solid round steel. Shafting bar is cold drawn or turned and polished to a tighter diameter tolerance and smoother finish, so it can be used for shafts with little or no machining. Ordinary MS round bar is hot rolled with a looser tolerance and a black (mill scale) surface. For the same diameter, the weight per metre is practically the same.
