How the 413130 model number is decoded
4T-413130 is the NTN 4T catalogue entry for a 150×250×80 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-413130 integrates both rows in one article: the 80 mm overall width and the internal clearance are ground and set by NTN, so there is no field adjustment dimension. The fatigue load limit Cu printed for 4T-413130 is 79.5 kN — the equivalent-load floor below which high reliability is expected even under contamination in the adjusted-life equation. Because the unit is preset, mounting 4T-413130 resembles mounting a double-row spherical or cylindrical bearing: seat the unit, clamp axially to the stated end cover torque, and verify rotation — no end-play measurement is required. Fillet radii and shoulder heights must follow the 2203E mounting table for 4T-413130; the double cup must seat square across its full 80 mm width.
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
- 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
- cage damage when the unit is lifted by one cone instead of the double cup during fitting
- thermal distress when the oil supply sized for one row starves the second row
Selection pitfalls — read before you substitute
- At 150 mm bore the 4T-413130 unit needs hydraulic or crane-assisted fitting and a verified oil supply; manual methods cannot control seating at the 540 kN C level.
- The 430 light plan keeps 4T-413130 narrower and faster than the 432 heavy execution of the same 150 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-413130 feeds the two roller complements evenly; a single-side feed starves the far row.
- The internal clearance of 4T-413130 is factory-set: no end-play adjustment exists at mounting, and any attempt to set preload with a shaft nut overloads one row.
- Never interchange a TDO double-row unit with two single-row bearings of similar size: the 80 mm width, load spread and clearance logic of 4T-413130 are unit-specific.
- The 540/805 kN ratings and 79.5 kN Cu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-413130; 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-413130?
4T-413130 is a double-row tapered roller bearing of TDO (back-to-back) construction: 150 mm bore, 250 mm outside diameter and 80 mm overall width. From NTN Ball and Roller Bearings CAT.No.2203E: C 540 kN, C0 805 kN, Cu 79.5 kN, grease limiting speed 1,200 r/min, oil speed 1,500 r/min, mass about 14.6 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 150 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-413130 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-413130 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 80 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 413130 mean?
With no letter suffix, 413130 is the basic open double-row execution: steel cages, factory-set internal clearance, no feature suffix in the order code.
Why does 4T-413130 list two speeds, 1,200 and 1,500 r/min?
The lower figure, 1,200 r/min, is the grease-lubricated limiting speed for the two rows and their cages. With oil lubrication NTN rates 4T-413130 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.
