How the 567-563-NTN model number is decoded
The NTN 2203E inch table prints 4T-567/563 at 73.025 mm bore (2.875 in), 127 mm cup OD and 36.512 mm assembled T, with a grease limiting speed of 2,900 r/min and an oil ceiling of 3,800 r/min. Unlike ISO 355 metric numbers, this ABMA code does not encode the bore arithmetically: 567 identifies the cone of 73.025 mm (2.875 in) bore by catalogue lookup, and 563 fixes the 127 mm OD. The 2.5 kN of dynamic capacity per millimetre of bore summarises the 181 kN rating over the 73.025 mm bore — sanity-check any interchange candidate against this ratio and the 36.512 mm T. Housing fitment sequence for 4T-567/563: press the 563 cup square into the 127 mm seat first, then bring the 567 cone (on its 73.025 mm shaft) into adjustment — the two references are separate engineering parts that happen to ship as one set. Back-to-back (O) and face-to-face (X) arrangements of two 4T-567/563 sets react differently to shaft bending; choose the orientation for the moment load before locking shoulder geometry.
Typical equipment & failure modes
Common applications
- heavy truck and bus drive-axle differentials
- plant gearboxes on inch-dimensioned shaft lines
- large conveyor head pulleys in bulk-handling plant
- paper-machine and calender roll supports
Known failure patterns
- cone-rib and roller large-end smearing when the adjusted pair runs with preload but starved lubricant film
- 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
- 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 73.025 mm cone by induction heating (max 120 °C) and the 127 mm cup with a press sleeve; at 1820 g a cocked ring brinells the raceway directly.
- The pure-numeric inch family at 73.025 mm bore (127×36.512 mm assembled) is one of several inch families sharing similar bores; cross-series swaps change OD, T and contact angle, so match the full 567/563 reference at purchase.
- Do not confuse T (36.512 mm, the assembled cone-plus-cup width) with the cone width when drawing spacers; an abutment sized to T leaves the cup unseated.
- Inch and metric bores collide on paper — 73.025 mm is 2.875 in, not a round metric size; a metric bearing that seems 0.1 mm off will not seat on the inch shaft.
- Never drive the 127 mm cup home through the rollers: fitting force goes through the ring faces only, or brinell marks release as noise within the first running hours.
- The 181/229 kN ratings here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-567/563; 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-567/563?
4T-567/563 is an inch-series single-row tapered roller bearing to the ABMA boundary plan: 73.025 mm bore (2.875 in), 127 mm outside diameter and 36.512 mm assembled width T (5 × 1.437 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 181 kN, C0 229 kN, grease limiting speed 2,900 r/min, oil speed 3,800 r/min, mass about 1820 g. It is an open, separable cone/cup set with a pressed-steel cage.
Are the cone and cup of 4T-567/563 interchangeable separately?
Yes — ABMA inch parts are individually interchangeable: the 567 cone or the 563 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 181/229 kN ratings change with the cup.
What is the difference between 4T-567/563 and a metric ISO 355 tapered bearing?
4T-567/563 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 73.025×127×36.512 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-567/563 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 567/563 references; the 4T spelling is retained among this page's search aliases.
Why does 4T-567/563 list two speeds, 2,900 and 3,800 r/min?
The lower figure, 2,900 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-567/563 at 3,800 r/min because oil removes rib-contact heat better. Real limits still depend on pair adjustment, oil flow and cooling.
