How the NUP2216 model number is decoded
NUP2216 belongs to the NTN cylindrical roller range in NTN Ball and Roller Bearings CAT.No.2203E, under the ＊ ULTAGE new-generation specification: line-contact rollers between ground raceways for a 163 kN dynamic rating in the 80 mm bore. Reading the code: NUP for the two-direction-locating type, then the ISO 15 diameter/width series and the bore code — ×5 = 80 mm (00–03 use the 10/12/15/17 exception table). NTN prints the raceway diameters for this size — Fw 95.3 mm and Ew 125.3 mm — the envelope inside the 80/140 mm bore/OD where the rollers actually run. The 2.0 kN-per-mm-bore figure (163 kN over 80 mm) lets a NUP2216 interchange candidate be screened quickly against the same-envelope ball or roller alternatives. Mount the separable inner ring + roller assembly on the shaft first and slide the outer ring into the housing; never press the outer ring through the rollers of NUP2216.
Typical equipment & failure modes
Common applications
- large electric-motor and generator rotors
- cement and mining conveyor drive pulleys
- heavy industrial gearbox and reducer shafts
- large pump, turbine and compressor rotors
Known failure patterns
- roller smearing (microwelding) at start-up before the oil film builds under insufficient radial load
- cage wear accelerated when the EA high-capacity roller complement runs continuously above its thermal balance
- micro-pitting when the EHL film falls below the composite roughness at high specific load
- hard-particle indentation of raceways in unfiltered oil or open arrangements
- edge loading from shaft deflection beyond the 3–4 arc-minute alignment limit
Selection pitfalls — read before you substitute
- Induction-heat the 80 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 140 mm raceway.
- Never press either ring through the roller complement when fitting: mounting force goes through the ring faces, or the 140 mm race brinells and releases as vibration within hours.
- Open NUP2216 units need application-supplied sealing and a defined lubricant schedule; film thickness is the first failure mode for line contact when viscosity drops at the 80 mm contact.
- The NUP rib arrangement is not interchangeable with another prefix on the same 80 mm seat: inner ring two ribs + loose L-ring. Swapping NU for NJ changes axial location behaviour even though the 140×33 mm envelope matches.
- The NUP rib arrangement is not interchangeable with another prefix on the same 80 mm seat: inner ring two ribs + loose L-ring. Swapping NU for NJ changes axial location behaviour even though the 140×33 mm envelope matches.
- The 163/186 kN ratings, 22 kN Pu and 1890 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NUP2216 (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 NUP2216?
NUP2216 is an NTN NUP single-row cylindrical roller bearing to ISO 15: 80 mm bore, 140 mm OD and 33 mm width (3.15 × 5.512 × 1.299 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 163 kN, C0 186 kN, Pu 22 kN, grease limiting speed 4,400 r/min, oil 5,100 r/min, mass about 1890 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. NUP2216 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. NUP2216 is listed among the ＊ ULTAGE-marked executions in 2203E.
Can NUP2216 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 NUP2216?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 95.3 mm, Ew 125.3 mm. The nominal bore/OD remain 80/140 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 4,400 r/min grease / 5,100 r/min oil.
