Industrial 1166-3131-000W Bearing Housing

Separators INC 1166-3131-000W Bearing Housing is an industrial bearing housing unit (MPN 1166-3131-000W) designed to enclose and support a bearing within mechanical assemblies, providing a rigid housing and a mounting interface to frames or other support structures. The model is listed under the Separators INC brand as 1166-3131-000W on third‑party marketplaces such as MercadoLibre and eBay, confirming its identity as a dedicated housing component rather than a standalone bearing and signaling its use as a replacement part in compatible equipment. To ensure proper fit in a given application, buyers should verify the model number against seller specifications and accompanying equipment documentation, focusing on bore size, mounting pattern, and any insertion or seal requirements for their shaft and housing envelope. When verifying compatibility, it is prudent to compare the housing's envelope dimensions and mounting arrangement to the machinery's support structure and any adjacent components to avoid misalignment or interference.
