How the N1096 model number is decoded
For pure radial duty on a 480 mm shaft NTN supplies N1096: two integral ribs on the inner ring and a ribless separable outer ring; the open execution is rated 810 r/min on grease and 960 r/min on oil. On the NTN nameplate N states which ring carries the ribs, which determines whether N1096 floats or locates; the numeric remainder is the ISO 15 series and 480 mm bore reference, not a fit or clearance instruction. The separable ring comes off without removing the roller assembly from the other ring, which eases inspection and lets the non-locating arrangement accommodate thermal shaft growth. Selection arithmetic: Pu 197 kN is the fatigue load limit feeding the adjusted-life equation, and the C0/C ratio of 1.57 (2750/1750 kN) shows the high-static-capacity proportioning of this 480 mm bore. Heat the inner ring to max 120 °C for the 480 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
- wind-turbine gearbox planet and rotor shafts
- ship propulsion line shafts and reduction gears
- mining SAG/ball-mill drive shafts
- offshore drawworks and winch drums
Known failure patterns
- roller smearing (microwelding) at start-up before the oil film builds under insufficient radial load
- pressed-steel cage pocket wear when rollers skid at light load or too-thin lubricant
- micro-pitting when the EHL film falls below the composite roughness at high specific load
- brinelling from static overload or impact during handling
- electrical pitting on VFD-driven motor shafts without grounding protection
Selection pitfalls — read before you substitute
- At 480 mm bore, oil-lubricated arrangements toward 960 r/min need positive flow and drain design; the 124000 g N1096 ring stores enough heat that grease-only duty needs a careful relubrication calculation.
- The 100 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 480 mm inner ring.
- The N rib arrangement is not interchangeable with another prefix on the same 480 mm seat: inner ring ribbed, outer ring ribless. Swapping NU for NJ changes axial location behaviour even though the 700×100 mm envelope matches.
- Do not replace N1096 with a deep-groove ball bearing on rating alone: line contact gives 1750 kN radial capacity but the bearing cannot carry the thrust duty a ball bearing can and misalignment tolerance is only 3–4 arc-minutes.
- The EA high-capacity roller complement changes the load figure versus the basic execution of the same number; the 1750/2750 kN pair here belongs to N1096 as printed, not to the bare size.
- The 1750/2750 kN ratings, 197 kN Pu and 124000 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for N1096 (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 N1096?
N1096 is an NTN N single-row cylindrical roller bearing to ISO 15: 480 mm bore, 700 mm OD and 100 mm width (18.898 × 27.559 × 3.937 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 1750 kN, C0 2750 kN, Pu 197 kN, grease limiting speed 810 r/min, oil 960 r/min, mass about 124000 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. N1096 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. N1096 is supplied in the standard open execution shown in the table.
Can N1096 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 N1096?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 536 mm, Ew 644 mm. The nominal bore/OD remain 480/700 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 810 r/min grease / 960 r/min oil.
