How the N1007 model number is decoded
N1007 belongs to the NTN cylindrical roller range in NTN Ball and Roller Bearings CAT.No.2203E: line-contact rollers between ground raceways for a 25.1 kN dynamic rating in the 35 mm bore. 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 35 mm, with 62 mm OD and 14 mm width from the ISO 15 general plan. The 14 mm width and 13.5 mm section put the N1000 series in the extra-light (10/49) section; wide 22/23 variants at the same bore change OD, width and heat generation and are not drop-in swaps. Rating life at 25.1 kN C assumes clean oil and adequate film; the 2.82 kN Pu floor means contamination derating — not the C rating alone — governs adjusted life in dusty gearboxes. Provide axial location with an adjacent locating bearing rather than expecting the float cylindrical set to hold thrust on the 35 mm shaft.
Typical equipment & failure modes
Common applications
- pump and compressor crankshafts and rotors
- machine-tool gearbox and spindle radial sets
- material-handling drum and wheel shafts
- papermaking and printing auxiliary drives
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
- grease starvation and cage drag when relubrication intervals are extended past the grease life
- edge loading from shaft deflection beyond the 3–4 arc-minute alignment limit
- fretting corrosion on a loose rotating shaft seat
Selection pitfalls — read before you substitute
- On this 35 mm bore, shaft thermal growth can preload the inner ring if the fit is too tight; verify residual interference at temperature and confirm the float ring still slides after mounting N1007.
- The EA high-capacity roller complement changes the load figure versus the basic execution of the same number; the 25.1/23.2 kN pair here belongs to N1007 as printed, not to the bare size.
- Minimum radial load is frequently missed in oversized motor and fan selections: an underloaded N1007 skids at 12,000 r/min and fails by smearing long before L10 fatigue.
- The N rib arrangement is not interchangeable with another prefix on the same 35 mm seat: inner ring ribbed, outer ring ribless. Swapping NU for NJ changes axial location behaviour even though the 62×14 mm envelope matches.
- Open N1007 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 35 mm contact.
- The 25.1/23.2 kN ratings, 2.82 kN Pu and 176 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for N1007 (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 N1007?
N1007 is an NTN N single-row cylindrical roller bearing to ISO 15: 35 mm bore, 62 mm OD and 14 mm width (1.378 × 2.441 × 0.551 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 25.1 kN, C0 23.2 kN, Pu 2.82 kN, grease limiting speed 12,000 r/min, oil 15,000 r/min, mass about 176 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. N1007 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. N1007 is supplied in the standard open execution shown in the table.
Can N1007 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 N1007?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 42 mm, Ew 55 mm. The nominal bore/OD remain 35/62 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 12,000 r/min grease / 15,000 r/min oil.
