How the NUP216 model number is decoded

The NTN order number NUP216 denotes a 80×140×26 mm (3.15 × 5.512 × 1.024 in) cylindrical roller bearing in the NUP200 family, a pressed sheet-steel cage. On the NTN nameplate NUP states which ring carries the ribs, which determines whether NUP216 floats or locates; the numeric remainder is the ISO 15 series and 80 mm bore reference, not a fit or clearance instruction. The separable ring comes off without removing the roller assembly from the other ring, which eases inspection and lets the non-locating arrangement accommodate thermal shaft growth. The 1.5 kN-per-mm-bore figure (118 kN over 80 mm) lets a NUP216 interchange candidate be screened quickly against the same-envelope ball or roller alternatives. After mounting verify the outer ring slides axially by hand at ambient temperature; a stuck float ring in a NUP216 non-locating position preloads the bearing when the shaft grows.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Induction-heat the 80 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 140 mm raceway.
• The 26 mm width and abutment faces must be square to the axis; a tilted spacer concentrates load across the roller set and shows as uneven raceway polish on the 80 mm inner ring.
• Do not replace NUP216 with a deep-groove ball bearing on rating alone: line contact gives 118 kN radial capacity but the bearing only accepts small sustained axial guidance loads and misalignment tolerance is only 3–4 arc-minutes.
• The 30.0 mm section at 80 mm bore leaves a narrow oil path; with the standard cage the relubrication groove and oil-level design must keep grease from churning in the 26 mm-wide cavity.
• The EA high-capacity roller complement changes the load figure versus the basic execution of the same number; the 118/122 kN pair here belongs to NUP216 as printed, not to the bare size.
• The 118/122 kN ratings, 14.5 kN Pu and 1470 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for NUP216 (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.
