How the NF2219E model number is decoded
NF2219E is the wide (22) section of the NTN NF2200 dimension series for a 95 mm shaft — 315 kN of basic dynamic capacity in a 3840 g, open bearing. Reading the code: NF for the rib-on-each-ring type, then the ISO 15 diameter/width series and the bore code — ×5 = 95 mm (00–03 use the 10/12/15/17 exception table). At 3,800 r/min with oil versus 3,300 r/min with grease (a 500 r/min band), lubrication choice for NF2219E is a thermal decision, not just a sealing one. Mass 3840 g for the 95×170×43 mm NF2219E execution covers the pressed-steel cage and full roller complement; substitute on mass plus rating, not envelope alone. Heat the inner ring to max 120 °C for the 95 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
- 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
- inner-ring raceway spalling from overload in the line-contact Hertzian zone
- 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
- brinelling from static overload or impact during handling
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.
- 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 EA high-capacity roller complement changes the load figure versus the basic execution of the same number; the 315/370 kN pair here belongs to NF2219E as printed, not to the bare size.
- 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.
- Grease limiting speed 3,300 r/min and oil 3,800 r/min are different limits for NF2219E: the first is the cage/lubricant mechanical ceiling, the second assumes real oil flow rather than an oil bath.
- The 315/370 kN ratings, 41.5 kN Pu and 3840 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NF2219E (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 NF2219E?
NF2219E is an NTN NF 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. NF2219E 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. NF2219E is supplied in the standard open execution shown in the table.
Can NF2219E 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 NF2219E?
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.
