How the NF413 model number is decoded
NF413 belongs to the NTN cylindrical roller range in NTN Ball and Roller Bearings CAT.No.2203E: line-contact rollers between ground raceways for a 202 kN dynamic rating in the 65 mm bore. Numbering ties NF413 to its envelope: type code NF, series NF400, 65 mm bore; the 160×37 mm outline therefore swaps dimensionally with other ISO 15 bearings of the same code, though rib arrangements differ by prefix. The separable ring comes off without removing the roller assembly from the other ring, which eases inspection and lets the non-locating arrangement accommodate thermal shaft growth. Speed ratio check: limiting 3,600 r/min is .84 of the 4,300 r/min oil value for NF413; grease-churn heating closes that gap as fill quantity rises. On NF arrangements confirm which ring is separable before heating: forcing the ribbed ring off over the roller complement damages the cage and rib faces.
Typical equipment & failure modes
Common applications
- rolling-mill auxiliary drive shafts
- crusher and vibrating-screen drive shafts
- marine gearbox and deck-machinery shafts
- large electric-motor and generator rotors
Known failure patterns
- roller smearing (microwelding) at start-up before the oil film builds under insufficient radial load
- cage wear accelerated when the EA high-capacity roller complement runs continuously above its thermal balance
- roller-end and raceway scoring from inadequate oil flow under heavy radial load
- rolling-contact fatigue after the catalogue L10 life is exceeded
- false brinelling on standby machines exposed to external vibration
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.
- If the shaft must be located both ways, do not use NF413 alone: pair it with a locating bearing or specify the NUP execution with the matching loose rib ring from the 2203E table.
- 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 37 mm width and abutment faces must be square to the axis; a tilted spacer concentrates load across the roller set and shows as uneven raceway polish on the 65 mm inner ring.
- The EA high-capacity roller complement changes the load figure versus the basic execution of the same number; the 202/186 kN pair here belongs to NF413 as printed, not to the bare size.
- The 202/186 kN ratings, 21.9 kN Pu and 3500 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NF413 (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 NF413?
NF413 is an NTN NF 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. NF413 is one integral rib on each ring — separable inner ring with single-direction axial guidance and a defined shaft position.
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. NF413 is supplied in the standard open execution shown in the table.
Can NF413 take axial load and locate a shaft?
the NF design gives one-direction axial guidance via its single outer-ring rib. The loose rib ring still only suits light/short-duration axial guidance; heavy thrust belongs to a dedicated thrust bearing.
What do Fw and Ew mean for NF413?
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.
