How the N1060 model number is decoded
N1060 is the extra-light (10/49) section of the NTN N1000 dimension series for a 300 mm shaft — 950 kN of basic dynamic capacity in a 42900 g, open bearing. The leading N defines the rib arrangement (inner ring ribbed, outer ring ribless); the dimension-series digits and the two-digit bore code resolve to 300 mm, with 460 mm OD and 74 mm width from the ISO 15 general plan. the bare number is the standard-capacity open execution with the normal pressed-steel cage; quote the full N1060 designation when purchasing. Selection arithmetic: Pu 109 kN is the fatigue load limit feeding the adjusted-life equation, and the C0/C ratio of 1.41 (1340/950 kN) shows the high-static-capacity proportioning of this 300 mm bore. 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 N1060.
Typical equipment & failure modes
Common applications
- large turbine and generator rotor bearings
- wind-turbine gearbox planet and rotor shafts
- ship propulsion line shafts and reduction gears
- mining SAG/ball-mill drive 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
- micro-pitting when the EHL film falls below the composite roughness at high specific load
- brinelling from static overload or impact during handling
- edge loading from shaft deflection beyond the 3–4 arc-minute alignment limit
Selection pitfalls — read before you substitute
- At 300 mm bore, oil-lubricated arrangements toward 1,600 r/min need positive flow and drain design; the 42900 g N1060 ring stores enough heat that grease-only duty needs a careful relubrication calculation.
- Never press either ring through the roller complement when fitting: mounting force goes through the ring faces, or the 460 mm race brinells and releases as vibration within hours.
- The N rib arrangement is not interchangeable with another prefix on the same 300 mm seat: inner ring ribbed, outer ring ribless. Swapping NU for NJ changes axial location behaviour even though the 460×74 mm envelope matches.
- If the shaft must be located both ways, do not use N1060 alone: pair it with a locating bearing or specify the NUP execution with the matching loose rib ring from the 2203E table.
- The 74 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 300 mm inner ring.
- The 950/1340 kN ratings, 109 kN Pu and 42900 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for N1060 (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 N1060?
N1060 is an NTN N single-row cylindrical roller bearing to ISO 15: 300 mm bore, 460 mm OD and 74 mm width (11.811 × 18.11 × 2.913 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 950 kN, C0 1340 kN, Pu 109 kN, grease limiting speed 1,400 r/min, oil 1,600 r/min, mass about 42900 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. N1060 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. N1060 is supplied in the standard open execution shown in the table.
Can N1060 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 N1060?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 340 mm, Ew 420 mm. The nominal bore/OD remain 300/460 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 1,400 r/min grease / 1,600 r/min oil.
