How the N2216 model number is decoded

N2216 is the wide (22) section of the NTN N2200 dimension series for a 80 mm shaft — 163 kN of basic dynamic capacity in a 1890 g, open bearing. On the NTN nameplate N states which ring carries the ribs, which determines whether N2216 floats or locates; the numeric remainder is the ISO 15 series and 80 mm bore reference, not a fit or clearance instruction. Line contact between rollers and raceways gives N2216 high radial capacity but no tolerance for misalignment: beyond roughly 3–4 arc-minutes the roller ends edge-load and fatigue accelerates. Mass 1890 g for the 80×140×33 mm N2216 execution covers the pressed-steel cage and full roller complement; substitute on mass plus rating, not envelope alone. On N 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

  • marine gearbox and deck-machinery shafts
  • large electric-motor and generator rotors
  • cement and mining conveyor drive pulleys
  • heavy industrial gearbox and reducer shafts

Known failure patterns

  • inner-ring raceway spalling from overload in the line-contact Hertzian zone
  • cage distortion after a mounting blow carried through the roller set
  • roller-end and raceway scoring from inadequate oil flow under heavy radial load
  • hard-particle indentation of raceways in unfiltered oil or open arrangements
  • 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.
  • Wide (22/23) and light (10/49) executions at 80 mm bore share bore but not OD/width; check the full N2200 series code before substituting, because housing and shoulder geometry will not interchange.
  • The 33 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 80 mm inner ring.
  • The 30.0 mm section at 80 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 33 mm-wide cavity.
  • Wide (22/23) and light (10/49) executions at 80 mm bore share bore but not OD/width; check the full N2200 series code before substituting, because housing and shoulder geometry will not interchange.
  • The 163/186 kN ratings, 22 kN Pu and 1890 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for N2216 (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 N2216?

N2216 is an NTN N 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 163 kN, C0 186 kN, Pu 22 kN, grease limiting speed 4,400 r/min, oil 5,100 r/min, mass about 1890 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. N2216 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. N2216 is listed among the * ULTAGE-marked executions in 2203E.

Can N2216 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 N2216?

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 125.3 mm. The nominal bore/OD remain 80/140 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 4,400 r/min grease / 5,100 r/min oil.
