Before you interchange

Boundary dimensions are fixed by ISO 15, so the numbers above are dimensionally interchangeable. Internal features are not: compare the suffix (seal or shield, cage, clearance class, precision grade) and the load rating before substituting, and check the required tolerance class if the position is sensitive. When in doubt, send the application and we will confirm the closest equivalent.
