How the HH221440-HH221410 model number is decoded
NTN supplies this 3.813 in (96.838 mm) shaft position as 4T-HH221440/HH221410: cone HH221440, cup HH221410, profiled rollers and a pressed-steel cage, rated 490 kN basic dynamic and 610 kN static. Reading the designation: 4T-HH221440/HH221410 follows the ABMA inch convention — the number before the slash is the cone (inner ring with roller set and cage), the number after the slash is the cup (outer ring), and the extra-heavy HH family lettering ties the pair to its boundary plan. Contact-angle geometry of the extra-heavy HH family gives 4T-HH221440/HH221410 its radial/axial load split — at 490/610 kN the static rating is about 1.24× C, typical of inch tapered sets proportioned for combined duty. Cup-side note for HH221410: within the extra-heavy HH family tables the HH221440 cone is listed against several cup options, and it is the cup that fixes the 190.5 mm OD and the 57.15 mm assembled width — quote the full HH221440/HH221410 pair, never the cone alone. Back-to-back (O) and face-to-face (X) arrangements of two 4T-HH221440/HH221410 sets react differently to shaft bending; choose the orientation for the moment load before locking shoulder geometry.
Typical equipment & failure modes
Common applications
- marine winch and deck-machinery shafts
- crusher and screening-plant eccentric shafts
- heavy truck and bus drive-axle differentials
- plant gearboxes on inch-dimensioned shaft lines
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 damage from a mounting blow transmitted through the roller complement
- rolling-contact fatigue spalling after the catalogue L10 life at the actual combined load
Selection pitfalls — read before you substitute
- Mount the 96.838 mm cone by induction heating (max 120 °C) and the 190.5 mm cup with a press sleeve; at 7500 g a cocked ring brinells the raceway directly.
- The extra-heavy HH family is proportioned for a high thrust share; swapping to a lighter LM or pure-numeric series at the same 96.838 mm bore cuts axial capacity even when the envelope fits — re-verify the load split before downgrading.
- ABMA makes the 96.838×190.5 mm envelope interchangeable, not the ratings: NTN prints 490/610 kN for this execution and another make of the same number can differ in roller complement.
- Grease packs must leave free volume inside the 57.15 mm-wide set; over-greasing a pair churning near the oil-band speed of 2,600 r/min raises temperature and destroys the setting.
- Inch and metric bores collide on paper — 96.838 mm is 3.813 in, not a round metric size; a metric bearing that seems 0.1 mm off will not seat on the inch shaft.
- The 490/610 kN ratings here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-HH221440/HH221410; 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-HH221440/HH221410?
4T-HH221440/HH221410 is an inch-series single-row tapered roller bearing to the ABMA boundary plan: 96.838 mm bore (3.813 in), 190.5 mm outside diameter and 57.15 mm assembled width T (7.5 × 2.25 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 490 kN, C0 610 kN, grease limiting speed 1,900 r/min, oil speed 2,600 r/min, mass about 7500 g. It is an open, separable cone/cup set with a pressed-steel cage.
Are the cone and cup of 4T-HH221440/HH221410 interchangeable separately?
Yes — ABMA inch parts are individually interchangeable: the HH221440 cone or the HH221410 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 490/610 kN ratings change with the cup.
What is the difference between 4T-HH221440/HH221410 and a metric ISO 355 tapered bearing?
4T-HH221440/HH221410 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 96.838×190.5×57.15 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-HH221440/HH221410 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 HH221440/HH221410 references; the 4T spelling is retained among this page's search aliases.
Why does 4T-HH221440/HH221410 list two speeds, 1,900 and 2,600 r/min?
The lower figure, 1,900 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-HH221440/HH221410 at 2,600 r/min because oil removes rib-contact heat better. Real limits still depend on pair adjustment, oil flow and cooling.
