How to choose Pins & Shafts

Points to check when selecting, with the values for this product (Super Shaft).

1. 1. Select the diameter tolerance to suit the mating hole and application

   The outer diameter tolerance determines the fit with the hole. h7 and g6 lean toward clearance fits and are used for rotating or sliding shafts and positioning parts that are inserted and removed, while m6 leans toward interference fits and is used for press-fit retention. Choose based on whether the part must move or be fixed, together with the tolerance of the mating hole (such as H7).

2. 2. Determine the diameter to match the bearing bore or hole size

   This product: Diameter d 0.1～6.0 mm

   The diameter should match the bore of the bearing or bushing being combined, or the dimensions of the machined hole. Listed products are mostly small-diameter, at 0.1 to 10 mm. Thinner diameters are more prone to deflection and bending, so confirm that the diameter is sufficient for the load and support span.

3. 3. Select the length based on support span and insertion depth

   This product: Length L 2.0～65.0 mm

   Length is determined by the insertion depth and the distance between parts. Listed products range from 2 to 150 mm, and in some cases lengths over 50 mm are handled in separate series. Long, small-diameter combinations require attention to straightness and deflection.

4. 4. Choose the material according to the operating environment

   This product: Material SUS304

   SUS304 offers excellent corrosion resistance. SUS303 is a free-cutting stainless steel with added sulfur to improve machinability, and its corrosion resistance is slightly lower than that of SUS304. Select based on whether the environment involves moisture or chemicals, or whether machinability is the priority.

5. 5. Check hardness and surface treatment if wear is a concern

   This product: Hardness HV300 or more

   In applications involving sliding or repeated insertion and removal, surface hardness affects wear life. Listed products include examples with a hardness of 300HV. If higher wear resistance is required, check for surface treatments such as hardening or plating.

6. 6. Check end face geometry related to insertability

   Chamfers or radii at the ends affect ease of insertion into holes and prevent galling during press fitting. Parallel pins are sometimes classified into types such as Type A and Type B based on end shape differences. Select the end face geometry to suit the assembly method.
