8I84T400550.010-1

Product Description:

The 8I84T400550.010-1 is part of the 8I7 ACOPOS Inverters from B & R Automation, built with AMS 5732 steel that’s been heat-treated as per AMS 2759/1. The hardness sits in the HRC 44–48 range, giving it just enough bite to resist wear during constant use. The length is 0.550 inches, and the diameter comes in at a nominal 0.1905 inches, with a tolerance band between 0.1900 and 0.1910 inches. It’s machined to stay consistent under load without any noticeable distortion.

The outer surface holds to a 32 µin Ra max finish, nothing polished, just smooth enough to keep the edges clean and prevent buildup during install. Threading isn’t applied — it’s flat per Drawing 8I84T400, which means it’s designed to seat into place or slide-fit rather than screw in. There’s no finish added, either — kept as-forged or as-machined to stick close to spec and avoid extra coating layers. Tolerance on the total length is held within ±0.010 inches, so batch-to-batch variation stays tight. The flexibility in mounting and connection options enhances adaptability, allowing equipment designers to optimize system layouts without compromising functionality or accessibility.

Best used in industrial systems where solid mechanical fit matters more than looks. This part doesn’t twist, doesn’t flex, and fits clean into slots designed around B&R automation hardware. Its small size helps it disappear once installed, but it plays a core role in locking assemblies in place. The high hardness and tight diameter range mean once it’s in, it doesn’t move unless it’s meant to. The 8I84T400550.010-1 works like a hidden spine inside the inverter assembly — not seen, but essential. Efficient thermal management through advanced cooling methods helps prevent overheating and prolongs component lifespan during continuous or high-load operation cycles.
