How the NJ416-NTN model number is decoded
NJ416 is the heavy (04) section of the NTN NJ400 dimension series for a 80 mm shaft — 330 kN of basic dynamic capacity in a 7140 g, open bearing. The leading NJ defines the rib arrangement (inner ring two ribs + one outer rib); the dimension-series digits and the two-digit bore code resolve to 80 mm, with 200 mm OD and 48 mm width from the ISO 15 general plan. 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. Thermal planning around the 3,000 r/min grease ceiling should include the cage type (a pressed sheet-steel cage) and oil-flow option to 3,500 r/min for continuously high-duty 80 mm positions. Housing and shaft fillets must clear the ring chamfers of NJ416; an oversized radius locks the ring on its face and tilts the 48 mm-wide seat.
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
- roller smearing (microwelding) at start-up before the oil film builds under insufficient radial load
- cage distortion after a mounting blow carried through the roller set
- micro-pitting when the EHL film falls below the composite roughness at high specific load
- false brinelling on standby machines exposed to external vibration
- brinelling from static overload or impact during handling
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.
- Open NJ416 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 NJ rib arrangement is not interchangeable with another prefix on the same 80 mm seat: inner ring two ribs + one outer rib. Swapping NU for NJ changes axial location behaviour even though the 200×48 mm envelope matches.
- The 48 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 80 mm inner ring.
- 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 330/315 kN ratings, 34.5 kN Pu and 7140 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NJ416 (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 NJ416?
NJ416 is an NTN NJ 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. NJ416 is two integral ribs on the inner ring and one rib on the outer ring — it locates the shaft in one axial direction.
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. NJ416 is supplied in the standard open execution shown in the table.
Can NJ416 take axial load and locate a shaft?
the NJ design accepts axial load in one direction and provides one-way shaft location. For two-direction location use an NUP execution or an NJ pair with loose rib rings.
What do Fw and Ew mean for NJ416?
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.
