8H409 - Four Bolt Flanged Bearing Housing (A&I Products)

8H409 is a four-bolt flanged bearing housing (import) by A&I Products, used with 85mm OD bearings; a mechanical farm equipment component, not IT hardware.

The 8H409 is a four-bolt flanged bearing housing manufactured by A&I Products, primarily supplied for agricultural and farm equipment applications rather than IT or networking use. It is designed to accommodate bearings with an outside diameter of 3.346 inches (85mm) and features a bore of 1.250 inches. The housing is used in machinery such as tillage equipment, grain drills, and other farm implements where a mounted bearing assembly is required to support rotating shafts. According to reseller documentation, this part is cataloged as an aftermarket/import replacement housing and is listed as an equivalent/replacement for the NF209 part number. Given its mechanical, non-electronic nature, it falls outside the scope of IT hardware categories such as networking, servers, or storage equipment. It is instead classified within agricultural and industrial mechanical replacement parts.
