How the T2EE060 model number is decoded
In NTN Ball and Roller Bearings CAT.No.2203E, the NTN order number T2EE060 denotes the large-size ISO 355 tapered-roller family of metric tapered roller bearings, 60 mm bore, 115 mm outside diameter and 40 mm assembled width T (2.362 × 4.528 × 1.575 in) to the ISO 355 boundary plan. NTN also quotes this bearing with its ISO 355 dimension-series abbreviation, 2EE, which is the maker-neutral cross-reference for the 60×115 mm envelope; 4T is NTN's own tapered-roller brand mark on the parts. A tapered roller bearing reacts combined radial and one-direction axial load; NTN mounts T2EE060 cone and cup separately and adjusts end play or preload against a second bearing, so the arrangement locates the shaft in both directions. Speed planning uses both catalogue columns: grease 3,200 r/min is the cage/rib mechanical ceiling for T2EE060, oil 4,300 r/min is available with circulating oil — a 1,100 r/min margin at this size. Mount the 60 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 T2EE060.
Typical equipment & failure modes
Common applications
- paper-machine press-section rolls
- large agricultural and forestry machine axles
- heavy industrial gearboxes and crane travel drives
- rolling-mill auxiliary and pinion-stand shafts
Known failure patterns
- cone-raceway spalling at the large rib when preload is set too high for the lubricant film
- 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
- pressed-steel cage pocket wear from roller skid at light radial load and high speed
- fretting corrosion on a loose cone seat that creeps under rotating load
Selection pitfalls — read before you substitute
- Mount the 60 mm cone by induction heating (max 120 °C) and the cup with a press sleeve; the 1860 g ring mass makes cocking during fitting a direct raceway-brinelling risk.
- The large-size ISO 355 tapered-roller family at 60 mm bore (115×40 mm assembled) carries more capacity than the lighter 320/329 sections but generates more preload heat; confirm oil availability before running near the 4,300 r/min oil ceiling.
- Minimum load matters at high speed: an unloaded T2EE060 at a large fraction of 3,200 r/min lets rollers skid and smear the cone rib; spring-preload lightly loaded pair arrangements.
- The 27.5 mm section leaves little room for an oversized shaft fillet; check the mounting-chamfer table for T2EE060 or the ring will bottom out on the radius instead of the shoulder face.
- Do not confuse T (40 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.
- The 209/249 kN ratings here are NTN Ball and Roller Bearings CAT.No.2203E figures for T2EE060 (ISO 355 2EE); 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 T2EE060?
T2EE060 is a metric 4T tapered roller bearing to ISO 355: 60 mm bore, 115 mm outside diameter and 40 mm assembled width T (2.362 × 4.528 × 1.575 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 209 kN, C0 249 kN (2203E prints no Pu for this size), grease limiting speed 3,200 r/min, oil speed 4,300 r/min, mass about 1860 g. It is an open, separable cone/cup bearing with a pressed-steel cage.
What does the 4T prefix mean on T2EE060?
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 (T2EE060); the lower-case 4t- factory spelling of the code is retained among the search aliases.
How does the T2EE060 designation encode the 60 mm bore and what is 2EE?
trailing dimension block 060 prints the 60 mm bore directly for this large-size T-code. The 115 mm OD and 40 mm assembled T follow the ISO 355 dimension-series plan. 2EE 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 T2EE060 list two speeds, 3,200 and 4,300 r/min?
The lower figure, 3,200 r/min, is the grease-lubricated limiting speed — the mechanical ceiling for the cage, rollers and cone-rib contact. With oil lubrication NTN rates T2EE060 at 4,300 r/min because oil removes rib-contact heat better. Real limits still depend on preload, oil flow and cooling.
What does the suffix on T2EE060 mean?
The T2/T4/T7-style code is NTN's large-size tapered roller designation within ISO 355; it identifies the dimension series and 60 mm bore directly, and remains an open 4T execution ordered under its own code.
