Home > Military & Defense > Custom Eccentric Shafts In 431 Stainless Steel Material

We supply our customer these custom eccentric shafts on a revolving blanket purchase order basis, typically at 350 pieces required annually. 431 material per AMS 5628 material was used to manufacture these tricky parts, with heat treat, dicronite finish per AMS 2530 not to exceed .0002" in thickness. Dimensional tolerances were very stringent on these parts, at +/- .0002" on many of the cross section diameters along the shaft. The hex socket drive was broached with engagement to be at .175" minimum and overall drill depth not to exceed .200".

The 350 pieces were manufactured domestically in the USA and were provided with full certs. Lead time for production is typically between 4 and 8 months from order, which is a great reason to set up a blanket purchase order with pre-set release dates.
