How the 4130-600UTG model number is decoded
The NTN 2203E double-row table prints 4T-4130/600UTG at 600 mm bore, 870 mm OD and 200 mm overall width, with a grease limiting speed of 250 r/min and an oil ceiling of 360 r/min. The 4T- prefix is NTN's tapered roller quality mark; 430 numbers the light TDO plan and 432 the heavy TDO plan — at the same 600 mm bore the 432 execution carries a wider, heavier section than the 430. Axial capacity is bidirectional because the rows are opposed: 4T-4130/600UTG locates the shaft in both directions with C0 8550 kN behind the static check of the more heavily loaded row. TDO construction means the two cone assemblies of 4T-4130/600UTG face away from each other inside one double cup: the load lines diverge outward, giving a wide effective spread and high moment stiffness for the 600 mm shaft. Induction heating to max 120 °C is the standard fitting method at this 600 mm bore; driving the unit home through the rollers brinells both rows at once.
Typical equipment & failure modes
Common applications
- mine hoist and dragline drum shafts
- cement-plant mill and kiln drive trains
- port-crane hoist and luffing gearboxes
- heavy press and forging-machine drives
Known failure patterns
- roller large-end smearing against the cone ribs when one row of the unit runs starved of lubricant
- brinelling of both rows from a mounting blow transmitted through the roller complements
- preload loss and hammering noise when the cup clamping loosens and the unit gains axial float
- pressed-steel cage pocket wear from roller skid at light load and high speed
- water-induced pitting when washdown reaches the open unit without external seals
Selection pitfalls — read before you substitute
- At 600 mm bore the 4T-4130/600UTG unit needs hydraulic or crane-assisted fitting and a verified oil supply; manual methods cannot control seating at the 5000 kN C level.
- The 430 light plan keeps 4T-4130/600UTG narrower and faster than the 432 heavy execution of the same 600 mm bore; where shock or a high thrust share dominates, verify whether the heavier 432-family row is the intended position.
- An unloaded 4T-4130/600UTG near 250 r/min lets rollers skid; ensure a minimum load or light spring preload on high-speed positions.
- At inspection do not mix the cone assemblies of 4T-4130/600UTG with another unit; rows are ground together and re-matching is not guaranteed in the field.
- Clamping the double cup with a cocked end cover pinches one row: tighten the 870 mm OD clamping uniformly around the circumference.
- The 5000/8550 kN ratings and 570 kN Cu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-4130/600UTG; internal geometry legitimately differs between manufacturers, so re-verify ratings, clearance class and suffix before substituting another make on a rated drive.
Frequently asked questions
What are the dimensions and catalogue ratings of NTN 4T-4130/600UTG?
4T-4130/600UTG is a double-row tapered roller bearing of TDO (back-to-back) construction: 600 mm bore, 870 mm outside diameter and 200 mm overall width. From NTN Ball and Roller Bearings CAT.No.2203E: C 5000 kN, C0 8550 kN, Cu 570 kN, grease limiting speed 250 r/min, oil speed 360 r/min, mass about 350 kg. It is an open, preset-clearance unit with pressed-steel cages.
What is the difference between the NTN 430 and 432 double-row series at 600 mm bore?
Both are TDO double-row tapered roller units, but 430 is the light plan and 432 the heavy plan: at the same bore the 432 execution is wider and heavier with higher load ratings. 4T-4130/600UTG belongs to the light-duty 430-family TDO double-row series. Large sizes continue the plans as 4130/4131/4230/4231 (430 family) and 3230/3231 (432 family).
Can the internal clearance of 4T-4130/600UTG be adjusted at mounting?
No. The TDO unit — two cone assemblies against one double cup — is ground and set by NTN at the factory, and the 200 mm overall width is the finished dimension. Mounting sets no end play: seat the unit square, clamp the cup uniformly and verify free rotation. Field re-adjustment overloads one row.
What do the suffix letters on 4130/600UTG mean?
Suffix reading on 4130/600UTG: UTG marks the ULTAGE specification for large NTN tapered rollers — upgraded material and internal design, printed with the ＊ symbol ahead of the order number; suffixed variants are separate order numbers and are not interchangeable articles.
Why does 4T-4130/600UTG list two speeds, 250 and 360 r/min?
The lower figure, 250 r/min, is the grease-lubricated limiting speed for the two rows and their cages. With oil lubrication NTN rates 4T-4130/600UTG at 360 r/min because oil removes heat from both roller rows better — the housing feed must reach both rows through the double cup.
