How the 413072UTG model number is decoded

4T-413072UTG is an NTN double-row tapered roller bearing of TDO (back-to-back) construction: two cone assemblies against one double cup, supplied as a preset unit of 360×540×134 mm. Reading the designation: the last two digits 72 are the bore code, ×5 = 360 mm (codes 00–03 use the 10/12/15/17 exception table); the leading digits place the bearing in the light-duty 430-family TDO double-row series. The 5.2 kN of dynamic capacity per millimetre of bore summarises the 1880 kN rating over the 360 mm bore — compare substitution candidates on this ratio and on the 134 mm width. Because the unit is preset, mounting 4T-413072UTG 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. Induction heating to max 120 °C is the standard fitting method at this 360 mm bore; driving the unit home through the rollers brinells both rows at once.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 360 mm bore the 4T-413072UTG unit needs hydraulic or crane-assisted fitting and a verified oil supply; manual methods cannot control seating at the 1880 kN C level.
• The 430 light plan keeps 4T-413072UTG narrower and faster than the 432 heavy execution of the same 360 mm bore; where shock or a high thrust share dominates, verify whether the heavier 432-family row is the intended position.
• Order by the full 413072UTG code including suffixes — U, X, DX, E1 and UTG variants share the 360 mm bore but are different articles with different internal geometry.
• The 90.0 mm section leaves little room for oversized shaft fillets; follow the 2203E chamfer table for 4T-413072UTG or the cones bottom out on the radius.
• An unloaded 4T-413072UTG near 460 r/min lets rollers skid; ensure a minimum load or light spring preload on high-speed positions.
• The 1880/2810 kN ratings and 218 kN Cu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-413072UTG; internal geometry legitimately differs between manufacturers, so re-verify ratings, clearance class and suffix before substituting another make on a rated drive.
