How the NUP1096 model number is decoded
The NTN order number NUP1096 denotes a 480×700×100 mm (18.898 × 27.559 × 3.937 in) cylindrical roller bearing in the NUP1000 family, a pressed sheet-steel cage. Digit by digit, NUP1096 reads as NUP (inner ring two ribs + loose L-ring), ISO 15 series, and bore 480 mm; trailing letters such as EA or E mark the cage/capacity execution and are part of the order number. With C 1750 kN and C0 2750 kN (C0/C ≈ 1.57) the bearing is proportioned for heavy radial load; the NUP design provides two-direction axial location via its loose rib ring, for light/moderate thrust guidance. The 3.6 kN-per-mm-bore figure (1750 kN over 480 mm) lets a NUP1096 interchange candidate be screened quickly against the same-envelope ball or roller alternatives. Keep the open bearing wrapped until fitting: the line-contact raceways of the 480 mm bore indent under a single hard particle, and the steel cage provides no sealing of its own.
Typical equipment & failure modes
Common applications
- ship propulsion line shafts and reduction gears
- mining SAG/ball-mill drive shafts
- offshore drawworks and winch drums
- heavy press and large gearbox main shafts
Known failure patterns
- roller smearing (microwelding) at start-up before the oil film builds under insufficient radial load
- cage wear accelerated when the EA high-capacity roller complement runs continuously above its thermal balance
- roller-end and raceway scoring from inadequate oil flow under heavy radial load
- hard-particle indentation of raceways in unfiltered oil or open arrangements
- rolling-contact fatigue after the catalogue L10 life is exceeded
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 NUP1096 ring stores enough heat that grease-only duty needs a careful relubrication calculation.
- Wide (22/23) and light (10/49) executions at 480 mm bore share bore but not OD/width; check the full NUP1000 series code before substituting, because housing and shoulder geometry will not interchange.
- Grease limiting speed 810 r/min and oil 960 r/min are different limits for NUP1096: the first is the cage/lubricant mechanical ceiling, the second assumes real oil flow rather than an oil bath.
- Never press either ring through the roller complement when fitting: mounting force goes through the ring faces, or the 700 mm race brinells and releases as vibration within hours.
- Minimum radial load is frequently missed in oversized motor and fan selections: an underloaded NUP1096 skids at 810 r/min and fails by smearing long before L10 fatigue.
- The 1750/2750 kN ratings, 197 kN Pu and 124000 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NUP1096 (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 NUP1096?
NUP1096 is an NTN NUP 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. NUP1096 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. NUP1096 is supplied in the standard open execution shown in the table.
Can NUP1096 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 NUP1096?
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.
