How to Identify an Industrial Bearing by Measurement

Measure ID/OD/width, confirm series, and cross reference safely—without tearing down your whole machine.

Most bearings can be narrowed down with:

• Inner diameter (ID)
• Outer diameter (OD)
• Width (W)

Common types include deep groove ball, tapered roller, spherical roller, needle, and thrust bearings.

Do not assume an interchange is safe unless you verify:

• Clearance (C3/C4)
• Sealing (2RS/ZZ/open)
• Load rating needs
• Speed rating needs
• Lubrication type

Use Cross Reference to compare equivalents, then validate with Technical Data.
