How the 07096-07196 model number is decoded
4T-07096/07196 is the NTN 4T catalogue entry for a 25.159×50.005×13.495 mm inch tapered roller bearing — an ABMA-dimensioned cone/cup set, not an ISO 355 metric bearing, even though the table quotes metric equivalents. Cone and cup of 4T-07096/07196 are separately stocked parts: a worn 07196 cup can be replaced against the existing 07096 cone, provided the new cup carries the identical reference — pairing across references changes the 13.495 mm assembled width and the rating. Speed planning uses both catalogue columns: grease 7,500 r/min is the mechanical ceiling for 4T-07096/07196, oil 10,000 r/min with circulating oil — a 2,500 r/min margin at this size. Cup-side note for 07196: within the pure-numeric inch family tables the 07096 cone is listed against several cup options, and it is the cup that fixes the 50.005 mm OD and the 13.495 mm assembled width — quote the full 07096/07196 pair, never the cone alone. A single-row tapered bearing reacts thrust in one direction only; 4T-07096/07196 is adjusted against a second bearing so the shaft is located in both directions.
Typical equipment & failure modes
Common applications
- truck and trailer axle hubs on inch-dimensioned axles
- agricultural tractor transmission and PTO shafts
- industrial gearboxes built to inch shafting
- construction-equipment pivot and wheel positions
Known failure patterns
- rib-face scoring when the thrust share of the combined load exceeds what the cone rib of this size carries
- preload loss and noise after one bearing of the adjusted pair is replaced without resetting end play
- false brinelling on a stationary pair exposed to vibration during transport or standby
- pressed-steel cage pocket wear from roller skid at light radial load and high speed
- brinell marks on cone and cup raceways from impact during handling or hammer fitting
Selection pitfalls — read before you substitute
- Hub and pinion positions of this 25.159 mm class are adjusted in pairs; verify end play against the axle or gearbox drawing and re-torque after bedding-in instead of trusting the first setting on 4T-07096/07196.
- The pure-numeric inch family at 25.159 mm bore (50.005×13.495 mm assembled) is one of several inch families sharing similar bores; cross-series swaps change OD, T and contact angle, so match the full 07096/07196 reference at purchase.
- Inch and metric bores collide on paper — 25.159 mm is 0.991 in, not a round metric size; a metric bearing that seems 0.1 mm off will not seat on the inch shaft.
- Quote the full 07096/07196 pair at ordering: the 07096 cone also ships against sibling cups, and a cup from another reference changes the 13.495 mm assembled width and the rating.
- Quote the full 07096/07196 pair at ordering: the 07096 cone also ships against sibling cups, and a cup from another reference changes the 13.495 mm assembled width and the rating.
- The 28.8/27.9 kN ratings here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-07096/07196; 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-07096/07196?
4T-07096/07196 is an inch-series single-row tapered roller bearing to the ABMA boundary plan: 25.159 mm bore (0.991 in), 50.005 mm outside diameter and 13.495 mm assembled width T (1.969 × 0.531 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 28.8 kN, C0 27.9 kN, grease limiting speed 7,500 r/min, oil speed 10,000 r/min, mass about 120 g. It is an open, separable cone/cup set with a pressed-steel cage.
Are the cone and cup of 4T-07096/07196 interchangeable separately?
Yes — ABMA inch parts are individually interchangeable: the 07096 cone or the 07196 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 28.8/27.9 kN ratings change with the cup.
What is the difference between 4T-07096/07196 and a metric ISO 355 tapered bearing?
4T-07096/07196 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 25.159×50.005×13.495 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-07096/07196 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 07096/07196 references; the 4T spelling is retained among this page's search aliases.
Why does 4T-07096/07196 list two speeds, 7,500 and 10,000 r/min?
The lower figure, 7,500 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-07096/07196 at 10,000 r/min because oil removes rib-contact heat better. Real limits still depend on pair adjustment, oil flow and cooling.
