Precision ground shafts are available from Misumi in 26 geometries and shapes in hardened tool steel, SUS440C and SUS304 with plating options. The 52100 (bearing steel) may be used with typical linear applications. The SUS440C stainless steel is suitable for clean room environments or when introduced into rough conditions such as high humidity or unstable temperatures. Misumi allows customers to specify all finishing dimensions such as diameter, length, thread size at the time of ordering, without the need for a design drawing.
