How the 32036XUUTG model number is decoded
32036XUUTG is a metric single-row tapered roller bearing in the NTN 4T programme: a pressed-steel cage guides profiled rollers between a separable cone and cup on the 180×280 mm ISO 355 envelope, with 64 mm overall assembled width T. Digit by digit, the bare number identifies the low-section 32000 family tuned for low friction and a bore code resolving to 180 mm; 280 mm OD and 64 mm assembled T are the matching ISO 355 boundary dimensions shared with other makers of the same dimension series. Individually mounted, 32036XUUTG takes axial force in one direction only; two bearings are arranged face-to-face (X) or back-to-back (O) according to the moment stiffness and misalignment the shaft requires. Catalogue mass of the 32036XUUTG set is 14500 g (0.571 lb cone + cup); abutment and shaft shoulder design must carry that mass square to the axis. Mount the 180 mm-bore cone on the shaft first (induction heat, max 120 °C), fit the cup square in its housing, then set preload or end play; never drive the cup home through the rollers of 32036XUUTG.
Typical equipment & failure modes
Common applications
- large crusher and SAG/AG-mill drive shafts
- wind-turbine gearbox and main-shaft arrangements
- offshore crane and drawworks drums
- heavy haul railway traction gearboxes
Known failure patterns
- cup creep and housing fretting when the specified outer-ring press fit is not achieved
- rib scoring when axial load is carried beyond the cone rib capacity of the adjusted pair
- preload loss from racewear when one bearing of the paired set is replaced without re-adjusting end play
- cage damage from a mounting blow delivered through the roller complement instead of the ring face
- brinell marks on cone and cup raceways from impact during handling or hammering during fitting
Selection pitfalls — read before you substitute
- At 180 mm bore the 32036XUUTG set is adjusted with hydraulic nuts on large mill and wind positions; follow the drive-up angle/end-play procedure, because manual torque methods cannot control preload at the 825 kN C level.
- The thin 64 mm section of 32036XUUTG is built for low friction and tight envelopes, not the heavy preload of a 322/323 set; over-tightening adjustment on this 180 mm bore smears the roller ends against the rib.
- Do not confuse T (64 mm assembled width of cone + cup) with the cone width when drawing spacers; an abutment sized to T instead of the ring width leaves the cup unseated.
- Do not confuse T (64 mm assembled width of cone + cup) with the cone width when drawing spacers; an abutment sized to T instead of the ring width leaves the cup unseated.
- Never fit the 180 mm cone by hammering the 280 mm cup: force for both press fits goes through the ring faces only, or brinell marks release as noise within the first running hours.
- The 825/1170 kN ratings and 111 kN Pu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 32036XUUTG (ISO 355 3FD); internal geometry legitimately differs between manufacturers, so re-verify ratings, adjustment and suffix before substituting another make on a rated drive.
Frequently asked questions
What are the dimensions and catalogue ratings of NTN 32036XUUTG?
32036XUUTG is a metric 4T tapered roller bearing to ISO 355: 180 mm bore, 280 mm outside diameter and 64 mm assembled width T (7.087 × 11.024 × 2.52 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 825 kN, C0 1170 kN, Pu 111 kN, grease limiting speed 1,200 r/min, oil speed 1,700 r/min, mass about 14500 g. It is an open, separable cone/cup bearing with a pressed-steel cage.
What does the 4T prefix mean on 32036XUUTG?
4T is NTN's tapered roller bearing brand mark, stamped on the cone and cup in the factory. It identifies the NTN 4T programme and is not a dimension, so the catalogue and this page list the bare ISO 355 number (32036XUUTG); the lower-case 4t- factory spelling of the code is retained among the search aliases.
How does the 32036XUUTG designation encode the 180 mm bore and what is 3FD?
last two digits 36 are the ISO bore code, ×5 = 180 mm (codes 00–03 use the 10/12/15/17 exception table). The 280 mm OD and 64 mm assembled T follow the ISO 355 dimension-series plan. 3FD is the maker-neutral ISO 355 abbreviation for this dimension series (the same code other manufacturers print); 4T is NTN's own brand mark.
Why does 32036XUUTG list two speeds, 1,200 and 1,700 r/min?
The lower figure, 1,200 r/min, is the grease-lubricated limiting speed — the mechanical ceiling for the cage, rollers and cone-rib contact. With oil lubrication NTN rates 32036XUUTG at 1,700 r/min because oil removes rib-contact heat better. Real limits still depend on preload, oil flow and cooling.
What does the suffix on 32036XUUTG mean?
Suffix reading on 32036XUUTG: the XUUTG suffix marks the ULTAGE specification for large NTN tapered rollers — upgraded material and internal design for longer life inside the unchanged ISO 355 envelope; XU combines the X ISO boundary section with the U uprated internal design; the suffix is part of the order number and the variants are not interchangeable articles.
