How the NUP2222E model number is decoded
NUP2222E is an NTN NUP cylindrical roller bearing: the NJ rib arrangement plus a loose L-shaped rib ring on the inner ring — it locates the shaft in both axial directions, inside the 110×200×53 mm ISO 15 envelope. 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 110 mm, with 200 mm OD and 53 mm width from the ISO 15 general plan. NTN prints two speed ceilings: 2,800 r/min grease and 3,300 r/min oil — the pressed-steel cage and lubricant film set the real limit at the 110 mm bore. Thermal planning around the 2,800 r/min grease ceiling should include the cage type (the high-capacity pressed-steel cage of the E execution) and oil-flow option to 3,300 r/min for continuously high-duty 110 mm positions. Housing and shaft fillets must clear the ring chamfers of NUP2222E; an oversized radius locks the ring on its face and tilts the 53 mm-wide seat.
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
- 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
- edge loading from shaft deflection beyond the 3–4 arc-minute alignment limit
- electrical pitting on VFD-driven motor shafts without grounding protection
Selection pitfalls — read before you substitute
- Induction-heat the 110 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 200 mm raceway.
- Grease limiting speed 2,800 r/min and oil 3,300 r/min are different limits for NUP2222E: the first is the cage/lubricant mechanical ceiling, the second assumes real oil flow rather than an oil bath.
- Minimum radial load is frequently missed in oversized motor and fan selections: an underloaded NUP2222E skids at 2,800 r/min and fails by smearing long before L10 fatigue.
- The 45.0 mm section at 110 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 53 mm-wide cavity.
- If the shaft must be located both ways, do not use NUP2222E alone: pair it with a locating bearing or specify the NUP execution with the matching loose rib ring from the 2203E table.
- The 425/515 kN ratings, 55 kN Pu are NTN Ball and Roller Bearings CAT.No.2203E values for NUP2222E (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 NUP2222E?
NUP2222E is an NTN NUP single-row cylindrical roller bearing to ISO 15: 110 mm bore, 200 mm OD and 53 mm width (4.331 × 7.874 × 2.087 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 425 kN, C0 515 kN, Pu 55 kN, grease limiting speed 2,800 r/min, oil 3,300 r/min. 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. NUP2222E 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. NUP2222E is supplied in the standard open execution shown in the table.
Can NUP2222E 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 NUP2222E?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 132.5 mm. The nominal bore/OD remain 110/200 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 2,800 r/min grease / 3,300 r/min oil.
