How the HH221430-HH221410 model number is decoded

NTN supplies this 3 in (76.2 mm) shaft position as 4T-HH221430/HH221410: cone HH221430, cup HH221410, profiled rollers and a pressed-steel cage, rated 490 kN basic dynamic and 610 kN static. The 4T prefix is NTN's tapered roller quality mark stamped on both parts; it is a brand mark, not a size code, so cross-references quote HH221430/HH221410 without it. Imperial cross-check for the drawing: 76.2×190.5×57.15 mm converts to 3 × 7.5 × 2.25 in; the ABMA envelope swaps with like-numbered inch parts but the 490/610 kN ratings are NTN-specific. Housing fitment sequence for 4T-HH221430/HH221410: press the HH221410 cup square into the 190.5 mm seat first, then bring the HH221430 cone (on its 76.2 mm shaft) into adjustment — the two references are separate engineering parts that happen to ship as one set. Mount the 76.2 mm cone with an induction heater (max 120 °C) and press the 190.5 mm cup with a sleeve; driving either ring through the rollers brinells the raceways.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount the 76.2 mm cone by induction heating (max 120 °C) and the 190.5 mm cup with a press sleeve; at 8710 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 76.2 mm bore cuts axial capacity even when the envelope fits — re-verify the load split before downgrading.
• Replacing one half of an adjusted pair without resetting end play negates the 57.15 mm T logic: re-adjust the set and re-verify the contact pattern rather than reusing the old spacer stack.
• Open 4T-HH221430/HH221410 sets have no seals: a hub or gearbox needs external sealing or the 1,900 r/min grease figure is meaningless once water reaches the cone rib.
• Replacing one half of an adjusted pair without resetting end play negates the 57.15 mm T logic: re-adjust the set and re-verify the contact pattern rather than reusing the old spacer stack.
• The 490/610 kN ratings here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-HH221430/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.
