How the N2219E model number is decoded
N2219E belongs to the NTN cylindrical roller range in NTN Ball and Roller Bearings CAT.No.2203E: line-contact rollers between ground raceways for a 315 kN dynamic rating in the 95 mm bore. Digit by digit, N2219E reads as N (inner ring ribbed, outer ring ribless), ISO 15 series, and bore 95 mm; trailing letters such as EA or E mark the cage/capacity execution and are part of the order number. The 37.5 mm radial section ((170−95)/2) frames the roller complement; capacity per millimetre of bore is about 3.3 kN/mm before application factors. The 95 mm (3.74 in) bore and 170 mm (6.693 in) OD are ISO 15 boundary values; fillet and shoulder dimensions must still come from the NTN mounting table for the 43 mm-wide ring. Provide axial location with an adjacent locating bearing rather than expecting the float cylindrical set to hold thrust on the 95 mm shaft.
Typical equipment & failure modes
Common applications
- heavy industrial gearbox and reducer shafts
- large pump, turbine and compressor rotors
- rolling-mill auxiliary drive shafts
- crusher and vibrating-screen drive shafts
Known failure patterns
- inner-ring raceway spalling from overload in the line-contact Hertzian zone
- pressed-steel cage pocket wear when rollers skid at light load or too-thin lubricant
- 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
- rolling-contact fatigue after the catalogue L10 life is exceeded
Selection pitfalls — read before you substitute
- Induction-heat the 95 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 170 mm raceway.
- Minimum radial load is frequently missed in oversized motor and fan selections: an underloaded N2219E skids at 3,300 r/min and fails by smearing long before L10 fatigue.
- Wide (22/23) and light (10/49) executions at 95 mm bore share bore but not OD/width; check the full N2200 series code before substituting, because housing and shoulder geometry will not interchange.
- Never press either ring through the roller complement when fitting: mounting force goes through the ring faces, or the 170 mm race brinells and releases as vibration within hours.
- The 37.5 mm section at 95 mm bore leaves a narrow oil path; with the E high-capacity cage the relubrication groove and oil-level design must keep grease from churning in the 43 mm-wide cavity.
- The 315/370 kN ratings, 41.5 kN Pu and 3840 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for N2219E (E high-capacity 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 N2219E?
N2219E is an NTN N single-row cylindrical roller bearing to ISO 15: 95 mm bore, 170 mm OD and 43 mm width (3.74 × 6.693 × 1.693 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 315 kN, C0 370 kN, Pu 41.5 kN, grease limiting speed 3,300 r/min, oil 3,800 r/min, mass about 3840 g. It is open, with the high-capacity pressed-steel cage of the E execution.
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. N2219E 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. N2219E is supplied in the standard open execution shown in the table.
Can N2219E 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 N2219E?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 112.5 mm, Ew 154.5 mm. The nominal bore/OD remain 95/170 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 3,300 r/min grease / 3,800 r/min oil.
