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.
