How the NF2210EA model number is decoded
NF2210EA is the wide (22) section of the NTN NF2200 dimension series for a 50 mm shaft — 98.5 kN of basic dynamic capacity in a 584 g, open bearing. Numbering ties NF2210EA to its envelope: type code NF, series NF2200, 50 mm bore; the 90×23 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. Selection arithmetic: Pu 11.9 kN is the fatigue load limit feeding the adjusted-life equation, and the C0/C ratio of 0.98 (97/98.5 kN) shows the high-static-capacity proportioning of this 50 mm bore. Keep the open bearing wrapped until fitting: the line-contact raceways of the 50 mm bore indent under a single hard particle, and the steel cage provides no sealing of its own.
Typical equipment & failure modes
Common applications
- pump and compressor crankshafts and rotors
- machine-tool gearbox and spindle radial sets
- material-handling drum and wheel shafts
- papermaking and printing auxiliary drives
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
- edge loading from shaft deflection beyond the 3–4 arc-minute alignment limit
- electrical pitting on VFD-driven motor shafts without grounding protection
Selection pitfalls — read before you substitute
- On this 50 mm bore, shaft thermal growth can preload the inner ring if the fit is too tight; verify residual interference at temperature and confirm the float ring still slides after mounting NF2210EA.
- The 20.0 mm section at 50 mm bore leaves a narrow oil path; with the EA pressed-steel-cage cage the relubrication groove and oil-level design must keep grease from churning in the 23 mm-wide cavity.
- If the shaft must be located both ways, do not use NF2210EA alone: pair it with a locating bearing or specify the NUP execution with the matching loose rib ring from the 2203E table.
- Grease limiting speed 6,200 r/min and oil 8,800 r/min are different limits for NF2210EA: the first is the cage/lubricant mechanical ceiling, the second assumes real oil flow rather than an oil bath.
- The EA high-capacity roller complement changes the load figure versus the basic execution of the same number; the 98.5/97 kN pair here belongs to NF2210EA as printed, not to the bare size.
- The 98.5/97 kN ratings, 11.9 kN Pu and 584 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NF2210EA (EA pressed-steel-cage 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 NF2210EA?
NF2210EA is an NTN NF single-row cylindrical roller bearing to ISO 15: 50 mm bore, 90 mm OD and 23 mm width (1.969 × 3.543 × 0.906 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 98.5 kN, C0 97 kN, Pu 11.9 kN, grease limiting speed 6,200 r/min, oil 8,800 r/min, mass about 584 g. It is open, with the EA high-capacity 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. NF2210EA 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. This page's bearing carries the EA pressed-steel-cage execution.
Can NF2210EA 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 NF2210EA?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 59.5 mm, Ew 81.5 mm. The nominal bore/OD remain 50/90 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 6,200 r/min grease / 8,800 r/min oil.
