How the T7FC060 model number is decoded
NTN supplies this 60 mm bore tapered roller position as T7FC060: one cone assembly, one cup, line-contact rollers and a steel cage, rated 161 kN basic dynamic and 186 kN static on the large-size ISO 355 tapered-roller family. NTN also quotes this bearing with its ISO 355 dimension-series abbreviation, 7FC, which is the maker-neutral cross-reference for the 60×125 mm envelope; 4T is NTN's own tapered-roller brand mark on the parts. 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. Selection: C 161 kN against C0 186 kN gives a C0/C ratio of 1.16 for the 60 mm bore, and the equivalent combined load must keep below the rating at the target L10 with the pair counted as one unit. After mounting check the contact pattern with marking blue: a pattern biased to the large or small roller end means the 60 mm pair is misadjusted and the 37 mm T set will edge-load in service.
Typical equipment & failure modes
Common applications
- rolling-mill auxiliary and pinion-stand shafts
- large conveyor and bucket-elevator pulleys
- mineral-processing feeder and crusher auxiliaries
- marine winch and deck-machinery shafts
Known failure patterns
- cup creep and housing fretting when the specified outer-ring press fit is not achieved
- preload loss from racewear when one bearing of the paired set is replaced without re-adjusting end play
- rib scoring when axial load is carried beyond the cone rib capacity of the adjusted pair
- cage fatigue when the pair is run continuously near the grease limiting speed without oil cooling
- false brinelling on a stationary paired set exposed to external vibration
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 2000 g ring mass makes cocking during fitting a direct raceway-brinelling risk.
- The large-size ISO 355 tapered-roller family at 60 mm bore (125×37 mm assembled) carries more capacity than the lighter 320/329 sections but generates more preload heat; confirm oil availability before running near the 3,700 r/min oil ceiling.
- ISO 355 makes the 60×125 mm envelope interchangeable but not the ratings: NTN prints 161/186 kN for this execution, and a cheaper same-number part can differ in roller complement and steel.
- The U/UTG/X/C/CA/D suffix variants of a base number share the bore but not the article: ordering T7FC060 by size alone can deliver the wrong contact-angle execution for a pinion position.
- ISO 355 makes the 60×125 mm envelope interchangeable but not the ratings: NTN prints 161/186 kN for this execution, and a cheaper same-number part can differ in roller complement and steel.
- The 161/186 kN ratings here are NTN Ball and Roller Bearings CAT.No.2203E figures for T7FC060 (ISO 355 7FC); 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 T7FC060?
T7FC060 is a metric 4T tapered roller bearing to ISO 355: 60 mm bore, 125 mm outside diameter and 37 mm assembled width T (2.362 × 4.921 × 1.457 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 161 kN, C0 186 kN (2203E prints no Pu for this size), grease limiting speed 2,800 r/min, oil speed 3,700 r/min, mass about 2000 g. It is an open, separable cone/cup bearing with a pressed-steel cage.
What does the 4T prefix mean on T7FC060?
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 (T7FC060); the lower-case 4t- factory spelling of the code is retained among the search aliases.
How does the T7FC060 designation encode the 60 mm bore and what is 7FC?
trailing dimension block 060 prints the 60 mm bore directly for this large-size T-code. The 125 mm OD and 37 mm assembled T follow the ISO 355 dimension-series plan. 7FC 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 T7FC060 list two speeds, 2,800 and 3,700 r/min?
The lower figure, 2,800 r/min, is the grease-lubricated limiting speed — the mechanical ceiling for the cage, rollers and cone-rib contact. With oil lubrication NTN rates T7FC060 at 3,700 r/min because oil removes rib-contact heat better. Real limits still depend on preload, oil flow and cooling.
What does the suffix on T7FC060 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.
