EZO – Interchange List

The interchange list is a working tool for cross‑referencing metric and inch references across multiple catalogs. It explains the checks that prevent false equivalence: ring geometry, chamfers, cage type, seal or shield construction, and clearance/preload differences that may not be obvious from a superficial match. The aim is to shorten the path from a legacy or competitor code to a reliable EZO reference while avoiding surprises in torque, noise or load capacity.

Use the list alongside dimensional tables. Where several EZO references appear valid, the notes suggest how to choose based on speed, temperature and sealing needs. The document also reminds users to confirm shaft/housing fits and to review application‑specific constraints such as food‑grade lubrication, electrical insulation or washdown. Treated as a checklist rather than a blind swap, interchange becomes a safe productivity tool.
