How the 5760-5735 model number is decoded

The NTN 2203E inch table prints 4T-5760/5735 at 76.2 mm bore (3 in), 135.733 mm cup OD and 44.45 mm assembled T, with a grease limiting speed of 2,700 r/min and an oil ceiling of 3,500 r/min. Reading the designation: 4T-5760/5735 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 pure-numeric inch family lettering ties the pair to its boundary plan. The 29.8 mm radial section over the 76.2 mm bore positions the contact line of the pair; abutment shoulders and spacers are dimensioned from that geometry, not from the bore alone. The printed 235/330 kN ratings belong to the assembled 5760+5735 pair; a sibling row using the same cone with a different cup carries its own rating row because the raceway track shifts with the cup. NTN grades inch 4T bearings as open bearings without integral seals; at 76.2 mm bore the application supplies sealing and the grease fill or oil feed.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount the 76.2 mm cone by induction heating (max 120 °C) and the 135.733 mm cup with a press sleeve; at 2750 g a cocked ring brinells the raceway directly.
• The pure-numeric inch family at 76.2 mm bore (135.733×44.45 mm assembled) is one of several inch families sharing similar bores; cross-series swaps change OD, T and contact angle, so match the full 5760/5735 reference at purchase.
• Fit selection follows the rotating ring: a rotating cone on a 76.2 mm shaft takes a k5/m5 seat, and a rotating cup reverses the logic — decide from the load diagram, not from habit.
• Open 4T-5760/5735 sets have no seals: a hub or gearbox needs external sealing or the 2,700 r/min grease figure is meaningless once water reaches the cone rib.
• Fit selection follows the rotating ring: a rotating cone on a 76.2 mm shaft takes a k5/m5 seat, and a rotating cup reverses the logic — decide from the load diagram, not from habit.
• The 235/330 kN ratings here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-5760/5735; 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.
