How the 413134UTG model number is decoded
In NTN Ball and Roller Bearings CAT.No.2203E, the order number 4T-413134UTG denotes the light-duty 430-family TDO double-row series — a 170 mm bore double-row tapered unit rated 705 kN basic dynamic and 900 kN static. Suffix reading on 413134UTG: 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. The 55.0 mm radial section over the 170 mm bore carries two roller rows across the 88 mm width; abutment shoulders must clear both cone bores and the double-cup OD. The internal clearance of 4T-413134UTG is set at the factory by the double cup and spacer-less grinding; do not attempt to re-adjust it with shaft nuts — the 88 mm overall width is the finished dimension. The open unit carries no seals; the housing of 4T-413134UTG must provide sealing and the grease fill or oil feed to both rows.
Typical equipment & failure modes
Common applications
- cement-plant mill and kiln drive trains
- port-crane hoist and luffing gearboxes
- heavy press and forging-machine drives
- large shredder and recycler main shafts
Known failure patterns
- roller large-end smearing against the cone ribs when one row of the unit runs starved of lubricant
- preload loss and hammering noise when the cup clamping loosens and the unit gains axial float
- brinelling of both rows from a mounting blow transmitted through the roller complements
- cage fatigue after continuous running near the grease limiting speed without oil cooling
- indentation of both raceways by hard particles in an open, unsealed arrangement
Selection pitfalls — read before you substitute
- At 170 mm bore the 4T-413134UTG unit needs hydraulic or crane-assisted fitting and a verified oil supply; manual methods cannot control seating at the 705 kN C level.
- The 430 light plan keeps 4T-413134UTG narrower and faster than the 432 heavy execution of the same 170 mm bore; where shock or a high thrust share dominates, verify whether the heavier 432-family row is the intended position.
- Clamping the double cup with a cocked end cover pinches one row: tighten the 280 mm OD clamping uniformly around the circumference.
- An unloaded 4T-413134UTG near 1,000 r/min lets rollers skid; ensure a minimum load or light spring preload on high-speed positions.
- The 705 kN C already includes two-row load sharing — do not double it when pairing the unit with a floating bearing in the L10 calculation.
- The 705/900 kN ratings and 86 kN Cu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-413134UTG; 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-413134UTG?
4T-413134UTG is a double-row tapered roller bearing of TDO (back-to-back) construction: 170 mm bore, 280 mm outside diameter and 88 mm overall width. From NTN Ball and Roller Bearings CAT.No.2203E: C 705 kN, C0 900 kN, Cu 86 kN, grease limiting speed 1,000 r/min, oil speed 1,500 r/min, mass about 19.2 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 170 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-413134UTG 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-413134UTG 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 88 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 413134UTG mean?
Suffix reading on 413134UTG: 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-413134UTG list two speeds, 1,000 and 1,500 r/min?
The lower figure, 1,000 r/min, is the grease-lubricated limiting speed for the two rows and their cages. With oil lubrication NTN rates 4T-413134UTG at 1,500 r/min because oil removes heat from both roller rows better — the housing feed must reach both rows through the double cup.
