How the 432222XU model number is decoded

In NTN Ball and Roller Bearings CAT.No.2203E, the order number 4T-432222XU denotes the heavy-duty 432-family TDO double-row series — a 110 mm bore double-row tapered unit rated 800 kN basic dynamic and 1210 kN static. Reading the designation: the last two digits 22 are the bore code, ×5 = 110 mm (codes 00–03 use the 10/12/15/17 exception table); the leading digits place the bearing in the heavy-duty 432-family TDO double-row series. The 7.3 kN of dynamic capacity per millimetre of bore summarises the 800 kN rating over the 110 mm bore — compare substitution candidates on this ratio and on the 121 mm width. The internal clearance of 4T-432222XU is set at the factory by the double cup and spacer-less grinding; do not attempt to re-adjust it with shaft nuts — the 121 mm overall width is the finished dimension. Mount 4T-432222XU as one article: lift on the double cup, never on a single cone, or the preset alignment of the two rows is disturbed.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount the 110 mm unit by induction heating (max 120 °C); at 15.8 kg a cocked lift damages the cages and ribs before the bearing ever runs.
• The 432 heavy plan gives 4T-432222XU its 121 mm width and 800 kN rating at the 110 mm bore; do not downgrade to a 430-family unit of the same bore without re-checking C, C0 and the 130 kN Cu.
• An unloaded 4T-432222XU near 1,500 r/min lets rollers skid; ensure a minimum load or light spring preload on high-speed positions.
• Clamping the double cup with a cocked end cover pinches one row: tighten the 200 mm OD clamping uniformly around the circumference.
• Never interchange a TDO double-row unit with two single-row bearings of similar size: the 121 mm width, load spread and clearance logic of 4T-432222XU are unit-specific.
• The 800/1210 kN ratings and 130 kN Cu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-432222XU; internal geometry legitimately differs between manufacturers, so re-verify ratings, clearance class and suffix before substituting another make on a rated drive.
