How the N2213 model number is decoded

N2213 is an NTN N cylindrical roller bearing: two integral ribs on the inner ring and a ribless separable outer ring — equivalent float behaviour with the separable ring on the housing side, inside the 65×120×31 mm ISO 15 envelope. Reading the code: N for the separable-outer-ring type, then the ISO 15 diameter/width series and the bore code — ×5 = 65 mm (00–03 use the 10/12/15/17 exception table). With C 133 kN and C0 149 kN (C0/C ≈ 1.12) the bearing is proportioned for heavy radial load; the N design is non-locating like NU but floats with the separable outer ring in the housing. Rating life at 133 kN C assumes clean oil and adequate film; the 18.2 kN Pu floor means contamination derating — not the C rating alone — governs adjusted life in dusty gearboxes. Housing and shaft fillets must clear the ring chamfers of N2213; an oversized radius locks the ring on its face and tilts the 31 mm-wide seat.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Induction-heat the 65 mm inner ring (max 120 °C) and mount it before fitting the outer ring; the ring mass makes square guidance essential — driving through the rollers brinells the 120 mm raceway.
• Do not replace N2213 with a deep-groove ball bearing on rating alone: line contact gives 133 kN radial capacity but the bearing cannot carry the thrust duty a ball bearing can and misalignment tolerance is only 3–4 arc-minutes.
• Never press either ring through the roller complement when fitting: mounting force goes through the ring faces, or the 120 mm race brinells and releases as vibration within hours.
• Wide (22/23) and light (10/49) executions at 65 mm bore share bore but not OD/width; check the full N2200 series code before substituting, because housing and shoulder geometry will not interchange.
• Minimum radial load is frequently missed in oversized motor and fan selections: an underloaded N2213 skids at 5,400 r/min and fails by smearing long before L10 fatigue.
• The 133/149 kN ratings, 18.2 kN Pu and 1370 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for N2213 (standard execution); other makes sharing the ISO 15 envelope revise internal geometry without changing the order number, so keep the 2203E reference with the specification for critical drives.
