How the 5584-5535 model number is decoded
In NTN Ball and Roller Bearings CAT.No.2203E, the order number 4T-5584/5535 denotes the pure-numeric inch family of NTN inch tapered roller bearings — cone 5584 and cup 5535 delivered as a matched, separable pair of 63.5 mm bore and 122.238 mm outside diameter. Letter prefixes inherited from the inch convention mark the load family: LM reads as light-medium, HM as heavy-medium, LL as extra-light, J-prefixed codes as metric-envelope families — 5584 sits in the pure-numeric inch family. Speed planning uses both catalogue columns: grease 3,100 r/min is the mechanical ceiling for 4T-5584/5535, oil 4,100 r/min with circulating oil — a 1,000 r/min margin at this size. Housing fitment sequence for 4T-5584/5535: press the 5535 cup square into the 122.238 mm seat first, then bring the 5584 cone (on its 63.5 mm shaft) into adjustment — the two references are separate engineering parts that happen to ship as one set. After bedding-in, re-check the end play of the adjusted 4T-5584/5535 pair — initial seating of the ring faces relaxes the setting slightly.
Typical equipment & failure modes
Common applications
- paper-machine and calender roll supports
- off-highway and forestry machine axles
- marine winch and deck-machinery shafts
- crusher and screening-plant eccentric shafts
Known failure patterns
- rib-face scoring when the thrust share of the combined load exceeds what the cone rib of this size carries
- cup creep and housing fretting when the cup seat is cut too loose for the rotating load
- flaking on one cone only when a bent shaft loads the O/X pair unevenly
- cage fatigue when the pair runs continuously near the grease limiting speed without oil cooling
- edge loading when shaft deflection exceeds the few arc-minutes an adjusted pair tolerates
Selection pitfalls — read before you substitute
- Mount the 63.5 mm cone by induction heating (max 120 °C) and the 122.238 mm cup with a press sleeve; at 2340 g a cocked ring brinells the raceway directly.
- The pure-numeric inch family at 63.5 mm bore (122.238×43.658 mm assembled) is one of several inch families sharing similar bores; cross-series swaps change OD, T and contact angle, so match the full 5584/5535 reference at purchase.
- Open 4T-5584/5535 sets have no seals: a hub or gearbox needs external sealing or the 3,100 r/min grease figure is meaningless once water reaches the cone rib.
- Quote the full 5584/5535 pair at ordering: the 5584 cone also ships against sibling cups, and a cup from another reference changes the 43.658 mm assembled width and the rating.
- Open 4T-5584/5535 sets have no seals: a hub or gearbox needs external sealing or the 3,100 r/min grease figure is meaningless once water reaches the cone rib.
- The 215/283 kN ratings here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-5584/5535; internal geometry legitimately differs between inch-series makers, so re-verify ratings, adjustment and the exact cone/cup references before substituting another brand on a rated drive.
Frequently asked questions
What are the dimensions and catalogue ratings of NTN 4T-5584/5535?
4T-5584/5535 is an inch-series single-row tapered roller bearing to the ABMA boundary plan: 63.5 mm bore (2.5 in), 122.238 mm outside diameter and 43.658 mm assembled width T (4.813 × 1.719 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 215 kN, C0 283 kN, grease limiting speed 3,100 r/min, oil speed 4,100 r/min, mass about 2340 g. It is an open, separable cone/cup set with a pressed-steel cage.
Are the cone and cup of 4T-5584/5535 interchangeable separately?
Yes — ABMA inch parts are individually interchangeable: the 5584 cone or the 5535 cup can be replaced by an identical reference from NTN or another ABMA-dimensioned maker. Pairing the cone with a different cup reference is a different catalogue row: OD, assembled T and the 215/283 kN ratings change with the cup.
What is the difference between 4T-5584/5535 and a metric ISO 355 tapered bearing?
4T-5584/5535 follows the ABMA inch boundary plan with cone/cup references; ISO 355 bearings use metric dimension-series numbers (302, 322, …). Even where a metric size looks close to 63.5×122.238×43.658 mm, the envelopes and contact angles differ — the two systems are not drop-in interchangeable; check every boundary value before substituting.
What does the 4T prefix on 4T-5584/5535 mean?
4T is NTN's tapered roller bearing quality mark, stamped on cone and cup in the factory. It identifies NTN's 4T programme and is not a dimension or variant code, so interchange lists quote the bare 5584/5535 references; the 4T spelling is retained among this page's search aliases.
Why does 4T-5584/5535 list two speeds, 3,100 and 4,100 r/min?
The lower figure, 3,100 r/min, is the grease-lubricated limiting speed — the mechanical ceiling for the cage, rollers and cone-rib contact. With oil lubrication NTN rates 4T-5584/5535 at 4,100 r/min because oil removes rib-contact heat better. Real limits still depend on pair adjustment, oil flow and cooling.
