Verification boundary

What still needs to match

Do not infer interchange
Internal clearanceTimken notes that radial internal clearance must be included when ordering the complete assembly.
Fits and tolerancesConfirm shaft/housing fits, backing diameters, chamfers, and applicable tolerance class.
Design and cageMatch the N/NJ/NU/NUP arrangement and exact suffix rather than relying only on boundary dimensions.
Operating conditionsCheck load direction, lubrication, speed, temperature, contamination, and axial displacement requirements.
