How the N2332 model number is decoded
N2332 is an NTN N cylindrical roller bearing: two integral ribs on the inner ring and a ribless separable outer ring — equivalent float behaviour with the separable ring on the housing side, inside the 160×340×114 mm ISO 15 envelope. Reading the code: N for the separable-outer-ring type, then the ISO 15 diameter/width series and the bore code — ×5 = 160 mm (00–03 use the 10/12/15/17 exception table). the bare number is the standard-capacity open execution with the normal pressed-steel cage; quote the full N2332 designation when purchasing. Speed ratio check: limiting 1,700 r/min is .85 of the 2,000 r/min oil value for N2332; grease-churn heating closes that gap as fill quantity rises. Provide axial location with an adjacent locating bearing rather than expecting the float cylindrical set to hold thrust on the 160 mm shaft.
Typical equipment & failure modes
Common applications
- ship propulsion line shafts and reduction gears
- mining SAG/ball-mill drive shafts
- offshore drawworks and winch drums
- heavy press and large gearbox main 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
- grease starvation and cage drag when relubrication intervals are extended past the grease life
- fretting corrosion on a loose rotating shaft seat
- electrical pitting on VFD-driven motor shafts without grounding protection
Selection pitfalls — read before you substitute
- At 160 mm bore, oil-lubricated arrangements toward 2,000 r/min need positive flow and drain design; the 49500 g N2332 ring stores enough heat that grease-only duty needs a careful relubrication calculation.
- If the shaft must be located both ways, do not use N2332 alone: pair it with a locating bearing or specify the NUP execution with the matching loose rib ring from the 2203E table.
- The EA high-capacity roller complement changes the load figure versus the basic execution of the same number; the 1190/1520 kN pair here belongs to N2332 as printed, not to the bare size.
- Grease limiting speed 1,700 r/min and oil 2,000 r/min are different limits for N2332: the first is the cage/lubricant mechanical ceiling, the second assumes real oil flow rather than an oil bath.
- The 114 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 160 mm inner ring.
- The 1190/1520 kN ratings, 141 kN Pu and 49500 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for N2332 (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 N2332?
N2332 is an NTN N single-row cylindrical roller bearing to ISO 15: 160 mm bore, 340 mm OD and 114 mm width (6.299 × 13.386 × 4.488 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 1190 kN, C0 1520 kN, Pu 141 kN, grease limiting speed 1,700 r/min, oil 2,000 r/min, mass about 49500 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. N2332 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. N2332 is supplied in the standard open execution shown in the table.
Can N2332 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 N2332?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 208 mm, Ew 292 mm. The nominal bore/OD remain 160/340 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 1,700 r/min grease / 2,000 r/min oil.
