How the NUP2219E model number is decoded
The NTN order number NUP2219E denotes a 95×170×43 mm (3.74 × 6.693 × 1.693 in) cylindrical roller bearing in the NUP2200 family, the high-capacity pressed-steel cage of the E execution. The leading NUP defines the rib arrangement (inner ring two ribs + loose L-ring); the dimension-series digits and the two-digit bore code resolve to 95 mm, with 170 mm OD and 43 mm width from the ISO 15 general plan. NTN prints two speed ceilings: 3,300 r/min grease and 3,800 r/min oil — the pressed-steel cage and lubricant film set the real limit at the 95 mm bore. The 3.3 kN-per-mm-bore figure (315 kN over 95 mm) lets a NUP2219E interchange candidate be screened quickly against the same-envelope ball or roller alternatives. Housing and shaft fillets must clear the ring chamfers of NUP2219E; an oversized radius locks the ring on its face and tilts the 43 mm-wide seat.
Typical equipment & failure modes
Common applications
- large pump, turbine and compressor rotors
- rolling-mill auxiliary drive shafts
- crusher and vibrating-screen drive shafts
- marine gearbox and deck-machinery shafts
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
- grease starvation and cage drag when relubrication intervals are extended past the grease life
- 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.
- Wide (22/23) and light (10/49) executions at 95 mm bore share bore but not OD/width; check the full NUP2200 series code before substituting, because housing and shoulder geometry will not interchange.
- Do not replace NUP2219E with a deep-groove ball bearing on rating alone: line contact gives 315 kN radial capacity but the bearing only accepts small sustained axial guidance loads and misalignment tolerance is only 3–4 arc-minutes.
- 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 NUP2219E as printed, not to the bare size.
- If the shaft must be located both ways, do not use NUP2219E alone: pair it with a locating bearing or specify the NUP execution with the matching loose rib ring from the 2203E table.
- The 315/370 kN ratings, 41.5 kN Pu and 3840 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NUP2219E (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 NUP2219E?
NUP2219E is an NTN NUP 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. NUP2219E is the NJ rib arrangement plus a loose L-shaped rib ring on the inner ring — it locates the shaft in both axial directions.
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. NUP2219E is supplied in the standard open execution shown in the table.
Can NUP2219E take axial load and locate a shaft?
the NUP design provides two-direction axial location via its loose rib ring, for light/moderate thrust guidance. 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 NUP2219E?
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.
