How the 413080UTG model number is decoded
4T-413080UTG is the NTN 4T catalogue entry for a 400×600×148 mm double-row tapered roller bearing — the TDO arrangement reacts radial load plus thrust in both directions without a second bearing. Unlike a pair of single-row bearings, the TDO unit of 4T-413080UTG integrates both rows in one article: the 148 mm overall width and the internal clearance are ground and set by NTN, so there is no field adjustment dimension. Axial capacity is bidirectional because the rows are opposed: 4T-413080UTG locates the shaft in both directions with C0 3700 kN behind the static check of the more heavily loaded row. The internal clearance of 4T-413080UTG is set at the factory by the double cup and spacer-less grinding; do not attempt to re-adjust it with shaft nuts — the 148 mm overall width is the finished dimension. The preset clearance suits the standard temperature range; unusual thermal gradients between shaft and housing call for a clearance review against the 400 mm size before ordering 4T-413080UTG.
Typical equipment & failure modes
Common applications
- large shredder and recycler main shafts
- power-plant mill and fan shafts
- rolling-mill roll-neck and pinion-stand positions
- mine hoist and dragline drum shafts
Known failure patterns
- edge loading on one row when the housing seats the double cup cocked across its width
- 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
- indentation of both raceways by hard particles in an open, unsealed arrangement
Selection pitfalls — read before you substitute
- At 400 mm bore the 4T-413080UTG unit needs hydraulic or crane-assisted fitting and a verified oil supply; manual methods cannot control seating at the 2390 kN C level.
- The 430 light plan keeps 4T-413080UTG narrower and faster than the 432 heavy execution of the same 400 mm bore; where shock or a high thrust share dominates, verify whether the heavier 432-family row is the intended position.
- Lubricant must reach both rows: a housing groove aligned to the cup mid-width of 4T-413080UTG feeds the two roller complements evenly; a single-side feed starves the far row.
- Grease packs must leave free volume across the 148 mm width; over-greasing a unit churning near the 580 r/min oil-band speed raises temperature and expels the grease.
- Order by the full 413080UTG code including suffixes — U, X, DX, E1 and UTG variants share the 400 mm bore but are different articles with different internal geometry.
- The 2390/3700 kN ratings and 276 kN Cu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-413080UTG; 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-413080UTG?
4T-413080UTG is a double-row tapered roller bearing of TDO (back-to-back) construction: 400 mm bore, 600 mm outside diameter and 148 mm overall width. From NTN Ball and Roller Bearings CAT.No.2203E: C 2390 kN, C0 3700 kN, Cu 276 kN, grease limiting speed 410 r/min, oil speed 580 r/min, mass about 130 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 400 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-413080UTG 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-413080UTG 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 148 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 413080UTG mean?
Suffix reading on 413080UTG: 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-413080UTG list two speeds, 410 and 580 r/min?
The lower figure, 410 r/min, is the grease-lubricated limiting speed for the two rows and their cages. With oil lubrication NTN rates 4T-413080UTG at 580 r/min because oil removes heat from both roller rows better — the housing feed must reach both rows through the double cup.
