ENG DEU USA 日本語 中文 ESP CAT FRA ITA HUN Home Dimensional accuracy DIMENSIONAL ACCURACY The figure and tables shown below indicate the typical dimensional tolerances achievable in a sintered part. For the correct interpretation of these data, it is important to highlight that: These tolerances can be affected by the geometry of the component, the type of material and the manufacturing process (sintering conditions and/or complementary operations). Please consult our Technical Department for analysis of designs, suggestions for improvement, and allocation of final tolerances: Contact In self-lubricating bearings, dimensional accuracy in diameter improves up to IT 5-7. In high temperature sintered materials, such as stainless steels, some soft magnetic materials and certain structural steels, dimensional accuracy is adversely affected by one IT, especially in diameter.
