How the N413 model number is decoded
N413 is the heavy (04) section of the NTN N400 dimension series for a 65 mm shaft — 202 kN of basic dynamic capacity in a 3500 g, open bearing. 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 202 kN and C0 186 kN (C0/C ≈ 0.92) 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. The 3.1 kN-per-mm-bore figure (202 kN over 65 mm) lets a N413 interchange candidate be screened quickly against the same-envelope ball or roller alternatives. Provide axial location with an adjacent locating bearing rather than expecting the float cylindrical set to hold thrust on the 65 mm shaft.
Typical equipment & failure modes
Common applications
- cement and mining conveyor drive pulleys
- heavy industrial gearbox and reducer shafts
- large pump, turbine and compressor rotors
- rolling-mill auxiliary drive shafts
Known failure patterns
- roller smearing (microwelding) at start-up before the oil film builds under insufficient radial load
- cage distortion after a mounting blow carried through the roller set
- roller-end and raceway scoring from inadequate oil flow under heavy radial load
- electrical pitting on VFD-driven motor shafts without grounding protection
- brinelling from static overload or impact during handling
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 160 mm raceway.
- Never press either ring through the roller complement when fitting: mounting force goes through the ring faces, or the 160 mm race brinells and releases as vibration within hours.
- The 47.5 mm section at 65 mm bore leaves a narrow oil path; with the standard cage the relubrication groove and oil-level design must keep grease from churning in the 37 mm-wide cavity.
- Open N413 units need application-supplied sealing and a defined lubricant schedule; film thickness is the first failure mode for line contact when viscosity drops at the 65 mm contact.
- Minimum radial load is frequently missed in oversized motor and fan selections: an underloaded N413 skids at 3,600 r/min and fails by smearing long before L10 fatigue.
- The 202/186 kN ratings, 21.9 kN Pu and 3500 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for N413 (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.
Frequently asked questions
What are the dimensions and catalogue data of N413?
N413 is an NTN N single-row cylindrical roller bearing to ISO 15: 65 mm bore, 160 mm OD and 37 mm width (2.559 × 6.299 × 1.457 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 202 kN, C0 186 kN, Pu 21.9 kN, grease limiting speed 3,600 r/min, oil 4,300 r/min, mass about 3500 g. It is open, with a pressed sheet-steel cage.
What is the difference between NU, NJ, NUP, N and NF cylindrical roller bearings?
The prefix states the rib arrangement: NU has two outer-ring ribs and a ribless inner ring (float, no axial load); NJ adds ribs for one-direction location; NUP adds a loose L-ring to locate both directions; N has two inner-ring ribs and a separable outer ring; NF has one rib per ring for one-direction guidance. N413 is two integral ribs on the inner ring and a ribless separable outer ring — equivalent float behaviour with the separable ring on the housing side.
What do the EA, E and ＊ suffixes mean on NTN cylindrical roller bearings?
EA is NTN's high-capacity design with a pressed sheet-steel cage and optimised roller complement in the same ISO 15 envelope; E marks the high-capacity design at the larger bores; the ＊ symbol printed before the code in the NTN catalogue marks the ULTAGE new-generation specification and is not typed as part of the order number. N413 is supplied in the standard open execution shown in the table.
Can N413 take axial load and locate a shaft?
the N design is non-locating like NU but floats with the separable outer ring in the housing. Provide axial location with an adjacent locating bearing (angular-contact, deep-groove or a paired NJ/NUP set).
What do Fw and Ew mean for N413?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 89.3 mm, Ew 135.3 mm. The nominal bore/OD remain 65/160 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 3,600 r/min grease / 4,300 r/min oil.
