Some ferromagnetism may be noticed due to cold working or welding. They typically have reasonable cryogenic and high temperature strength properties. Chromium content typically is in the range of 16 to 26%; nickel content is commonly less than 35%. Chamfered - Chamfered edges refer to a small bevel on the edges of the shaft. Chamfered edges assist with the location of components on the shaft. DIN - Standards for materials as set by Deutsches Institut für Normung E.V. DIN Specifications can be purchased from www.nssn.org/ Fit - The degree of contact between two mating surfaces such as a bearing bore and a shaft. Different applications require different fits. A slip fit is one where there is a small amount of clearance between the two mating parts allowing them to slide together quite easily. An interference fit is one where the actual sizes of the two mating parts overlap requiring a certain amount of pressure to assemble (eg. A shaft of around 7.994mm and a bearing of around 7.992mm bore). Ferritic - Magnetic stainless steels that have a low carbon content and contain chromium as the main alloying element. Ferromagnetism - Magnetism due to the presence of iron. HBW - Brinell Hardness HRB - Rockwell Hardness B Scale HRC - Rockwell Hardness C Scale HV - Vickers Hardness Linear Motion - Movement along a shaft as distinct from rotary motion which is movement around a shaft. Martensitic - Martensitic stainless steels are alloys of chromium and carbon. They are ferromagnetic, hardenable by heat treatments, and are usually less resistant to corrosion than some other grades of stainless steel. Chromium content usually does not exceed 18%, while carbon content may exceed 1.0 %. Precipitation Hardening - An alloy strengthening method. Performed with two heat treatments that result in the growth of extremely small uniform particles. The small particles strengthen the metal. RA - Roughness Average which is an average of the peaks and valleys of a material's surface profile. RMS - Root Mean Square is an alternative method of measuring the surface roughness. The value for RMS is generally about 10% higher than the RA value for the same surface. Rotary Motion - Movement around a shaft as distinct from linear motion which is movement along a shaft. Tolerance - The permissible limit of variation from the nominal size. For example an 8mm shaft may be represented as 8.000 mm +0.000 / - 0.008 which would mean that the actual shaft size may be anywhere from 7.992 and 8.000 mm. µm - Micron or thousandth of a millimeter (0.001mm).

Site Summary:
shafting.info is your one stop resource for all types of information on shafting. The pages are administered by Miniature Bearings Australia and provide technical and sourcing information for all types of shafting from precision ground to semi-precision rod. Materials discussed include plastics, aluminium, chrome steel, various grades of stainless steel, silver steel and titanium.
This site is not a point of sale. It is designed to provide information only and to hopefully point you in the right direction with your shafting enquiries. This may include links to Miniature Bearings Australia or it's distributors, and it may also include links to competitors sites.
User input is encouraged and forms are provided throughout the site to enable users to make corrections or provide additional data.
Online purchases of many types of shafting can be made through the Small Parts and Bearings online store which is linked directly to the Miniature Bearings Australia online catalogue. We also suggest that you may want to take a look at Couplings Information, Gearboxes Information and H.E. Supplies Hobby Parts.
