How the NUP416 model number is decoded
For pure radial duty on a 80 mm shaft NTN supplies NUP416: the NJ rib arrangement plus a loose L-shaped rib ring on the inner ring; the open execution is rated 3,000 r/min on grease and 3,500 r/min on oil. Numbering ties NUP416 to its envelope: type code NUP, series NUP400, 80 mm bore; the 200×48 mm outline therefore swaps dimensionally with other ISO 15 bearings of the same code, though rib arrangements differ by prefix. The 60.0 mm radial section ((200−80)/2) frames the roller complement; capacity per millimetre of bore is about 4.1 kN/mm before application factors. Rating life at 330 kN C assumes clean oil and adequate film; the 34.5 kN Pu floor means contamination derating — not the C rating alone — governs adjusted life in dusty gearboxes. Heat the inner ring to max 120 °C for the 80 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
- crusher and vibrating-screen drive shafts
- marine gearbox and deck-machinery shafts
- large electric-motor and generator rotors
- cement and mining conveyor drive pulleys
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
- brinelling from static overload or impact during handling
- hard-particle indentation of raceways in unfiltered oil or open arrangements
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 200 mm raceway.
- The 60.0 mm section at 80 mm bore leaves a narrow oil path; with the standard cage the relubrication groove and oil-level design must keep grease from churning in the 48 mm-wide cavity.
- The EA high-capacity roller complement changes the load figure versus the basic execution of the same number; the 330/315 kN pair here belongs to NUP416 as printed, not to the bare size.

- The 330/315 kN ratings, 34.5 kN Pu and 7140 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NUP416 (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 NUP416?
NUP416 is an NTN NUP single-row cylindrical roller bearing to ISO 15: 80 mm bore, 200 mm OD and 48 mm width (3.15 × 7.874 × 1.89 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 330 kN, C0 315 kN, Pu 34.5 kN, grease limiting speed 3,000 r/min, oil 3,500 r/min, mass about 7140 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. NUP416 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. NUP416 is supplied in the standard open execution shown in the table.
Can NUP416 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 NUP416?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 110 mm, Ew 170 mm. The nominal bore/OD remain 80/200 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 3,000 r/min grease / 3,500 r/min oil.
