Interchange notes
All brands build this designation to the same ISO 15 boundary dimensions (d, D, B), so the mounting envelope is interchangeable. For self-aligning ball bearings, matching dimensions is NOT enough: (1) Two ball rows run on a single spherical raceway in the outer ring, letting the bearing swivel to absorb shaft misalignment — replacing it with a same-size deep groove ball bearing removes this and turns misalignment into edge loading. (2) A 'K' suffix means a tapered bore (taper 1:12) for an adapter/withdrawal sleeve; clearance is set during mounting by drive-up, not by shaft fit, so the tapered- and cylindrical-bore versions are NOT interchangeable. (3) The wide 22/23 series is not equivalent to the normal 12/13 series — it changes permissible misalignment angle. (4) Match internal clearance (CN/C2/C3), which alters the self-aligning angle, plus seal (-2RS) and cage type. Load ratings (dynamic Cr, static C0r) are intentionally NOT listed here: they vary by brand and internal design and are a safety-critical selection parameter — read them directly from the manufacturer catalog linked in the table above.

FAQ
What bearings are equivalent to a 2217?
The 2217 is built to ISO 15 boundary dimensions 85×150×36 mm by SKF, NSK, FAG, NTN, KOYO, NACHI, Timken, INA. All share the same mounting envelope; match clearance, precision class and (where applicable) seal suffix before substituting.
What are the dimensions of a 2217 bearing?
Bore 85 mm, outer diameter 150 mm, B 36 mm (ISO 15).
Is the 2217 interchangeable with a same-size deep groove bearing?
No. The 2217 shares its 85×150×36 mm envelope, but its two ball rows sit on a spherical outer raceway so it can swivel and absorb shaft misalignment — a rigid deep groove bearing of the same size cannot. Also check the bore: a 'K' suffix is a 1:12 tapered bore for a sleeve and is not interchangeable with the straight-bore version. Match internal clearance (CN/C2/C3) and seal type.
Related sizes
Boundary-dimension cross-reference only. Per the applicable ISO standard (ISO 15 for ball, ISO 355 for tapered), the boundary dimensions are common across brands, so the mounting envelope is interchangeable. This is NOT a drop-in part equivalence. Internal clearance, precision class, seal/shield type (where applicable), cage material and factory lubrication are encoded in brand-specific suffixes and must be matched separately. Always verify against the manufacturer's catalog before substituting.
