How the NUP240E model number is decoded
In NTN Ball and Roller Bearings CAT.No.2203E, NUP240E appears as a 200 mm bore single-row cylindrical roller bearing (850 kN C / 1060 kN C0) with the high-capacity pressed-steel cage of the E execution, listed to the ISO 15 boundary plan. The leading NUP defines the rib arrangement (inner ring two ribs + loose L-ring); the dimension-series digits and the two-digit bore code resolve to 200 mm, with 360 mm OD and 58 mm width from the ISO 15 general plan. Line contact between rollers and raceways gives NUP240E high radial capacity but no tolerance for misalignment: beyond roughly 3–4 arc-minutes the roller ends edge-load and fatigue accelerates. Equivalent-load planning treats NUP240E as a pure radial bearing: keep P below 850 kN at the required L10, and let a paired angular-contact or thrust part carry any sustained axial component. Confirm the loose L-shaped rib ring is fitted and seated, since it is what turns the NJ-type arrangement into the two-direction-locating NUP set on the 200 mm shaft.
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
- pressed-steel cage pocket wear when rollers skid at light load or too-thin lubricant
- roller-end and raceway scoring from inadequate oil flow under heavy radial load
- hard-particle indentation of raceways in unfiltered oil or open arrangements
- hard-particle indentation of raceways in unfiltered oil or open arrangements
Selection pitfalls — read before you substitute
- At 200 mm bore, oil-lubricated arrangements toward 1,900 r/min need positive flow and drain design; the NUP240E ring stores enough heat that grease-only duty needs a careful relubrication calculation.
- Do not replace NUP240E with a deep-groove ball bearing on rating alone: line contact gives 850 kN radial capacity but the bearing only accepts small sustained axial guidance loads and misalignment tolerance is only 3–4 arc-minutes.
- Wide (22/23) and light (10/49) executions at 200 mm bore share bore but not OD/width; check the full NUP200 series code before substituting, because housing and shoulder geometry will not interchange.
- Minimum radial load is frequently missed in oversized motor and fan selections: an underloaded NUP240E skids at 1,600 r/min and fails by smearing long before L10 fatigue.
- Wide (22/23) and light (10/49) executions at 200 mm bore share bore but not OD/width; check the full NUP200 series code before substituting, because housing and shoulder geometry will not interchange.
- The 850/1060 kN ratings, 95 kN Pu are NTN Ball and Roller Bearings CAT.No.2203E values for NUP240E (E high-capacity 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 NUP240E?
NUP240E is an NTN NUP single-row cylindrical roller bearing to ISO 15: 200 mm bore, 360 mm OD and 58 mm width (7.874 × 14.173 × 2.283 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 850 kN, C0 1060 kN, Pu 95 kN, grease limiting speed 1,600 r/min, oil 1,900 r/min. It is open, with the high-capacity pressed-steel cage of the E execution.
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. NUP240E 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. NUP240E is supplied in the standard open execution shown in the table.
Can NUP240E 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 NUP240E?
Fw is the inner sub-assembly raceway/roller-set envelope diameter and Ew the outer-ring raceway diameter printed for geometric checks: Fw 243 mm. The nominal bore/OD remain 200/360 mm; Fw/Ew describe the rolling-contact path, and speeds still run to 1,600 r/min grease / 1,900 r/min oil.
