How the NU213-NTN model number is decoded

In NTN Ball and Roller Bearings CAT.No.2203E, NU213 appears as a 65 mm bore single-row cylindrical roller bearing (93 kN C / 94.5 kN C0) with a pressed sheet-steel cage, listed to the ISO 15 boundary plan. The leading NU defines the rib arrangement (outer ring ribbed, inner ring ribless); the dimension-series digits and the two-digit bore code resolve to 65 mm, with 120 mm OD and 23 mm width from the ISO 15 general plan. Line contact between rollers and raceways gives NU213 high radial capacity but no tolerance for misalignment: beyond roughly 3–4 arc-minutes the roller ends edge-load and fatigue accelerates. Mass 1000 g for the 65×120×23 mm NU213 execution covers the pressed-steel cage and full roller complement; substitute on mass plus rating, not envelope alone. Heat the inner ring to max 120 °C for the 65 mm interference fit and support the ring face square during fitting; cocking over a keyway brinells the raceway before first rotation.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Induction-heat the 65 mm inner ring (max 120 °C) and mount it before fitting the outer ring; the ring mass makes square guidance essential — driving through the rollers brinells the 120 mm raceway.
• Wide (22/23) and light (10/49) executions at 65 mm bore share bore but not OD/width; check the full NU200 series code before substituting, because housing and shoulder geometry will not interchange.
• The EA high-capacity roller complement changes the load figure versus the basic execution of the same number; the 93/94.5 kN pair here belongs to NU213 as printed, not to the bare size.
• Wide (22/23) and light (10/49) executions at 65 mm bore share bore but not OD/width; check the full NU200 series code before substituting, because housing and shoulder geometry will not interchange.
• Wide (22/23) and light (10/49) executions at 65 mm bore share bore but not OD/width; check the full NU200 series code before substituting, because housing and shoulder geometry will not interchange.
• The 93/94.5 kN ratings, 11.5 kN Pu and 1000 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NU213 (standard execution); other makes sharing the ISO 15 envelope revise internal geometry without changing the order number, so keep the 2203E reference with the specification for critical drives.
