How the NF2216EA model number is decoded
NF2216EA is the wide (22) section of the NTN NF2200 dimension series for a 80 mm shaft — 220 kN of basic dynamic capacity in a 2020 g, open bearing. Numbering ties NF2216EA to its envelope: type code NF, series NF2200, 80 mm bore; the 140×33 mm outline therefore swaps dimensionally with other ISO 15 bearings of the same code, though rib arrangements differ by prefix. Minimum radial load matters: an unloaded NF2216EA at high speed skids its rollers and smears the raceway; spring preload or the rotor weight typically covers the requirement in motors and pumps. Selection arithmetic: Pu 28.7 kN is the fatigue load limit feeding the adjusted-life equation, and the C0/C ratio of 1.10 (243/220 kN) shows the high-static-capacity proportioning of this 80 mm bore. Heat the inner ring to max 120 °C for the 80 mm interference fit and support the ring face square during fitting; cocking over a keyway brinells the raceway before first rotation.
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
- grease starvation and cage drag when relubrication intervals are extended past the grease life
- rolling-contact fatigue after the catalogue L10 life is exceeded
- rolling-contact fatigue after the catalogue L10 life is exceeded
Selection pitfalls — read before you substitute
- Induction-heat the 80 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 140 mm raceway.
- Grease limiting speed 3,900 r/min and oil 5,500 r/min are different limits for NF2216EA: the first is the cage/lubricant mechanical ceiling, the second assumes real oil flow rather than an oil bath.
- Open NF2216EA 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 80 mm contact.
- The EA high-capacity roller complement changes the load figure versus the basic execution of the same number; the 220/243 kN pair here belongs to NF2216EA as printed, not to the bare size.
- Do not replace NF2216EA with a deep-groove ball bearing on rating alone: line contact gives 220 kN radial capacity but the bearing cannot carry the thrust duty a ball bearing can and misalignment tolerance is only 3–4 arc-minutes.
- The 220/243 kN ratings, 28.7 kN Pu and 2020 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NF2216EA (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 NF2216EA?
NF2216EA is an NTN NF single-row cylindrical roller bearing to ISO 15: 80 mm bore, 140 mm OD and 33 mm width (3.15 × 5.512 × 1.299 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 220 kN, C0 243 kN, Pu 28.7 kN, grease limiting speed 3,900 r/min, oil 5,500 r/min, mass about 2020 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. NF2216EA 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 NF2216EA 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 NF2216EA?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 95.3 mm, Ew 127.3 mm. The nominal bore/OD remain 80/140 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 3,900 r/min grease / 5,500 r/min oil.
