Interchange notes
All brands build this designation to the same ISO 15 boundary dimensions (d, D, B), so the mounting envelope is interchangeable. For spherical roller bearings, matching dimensions is NOT enough: (1) Two rows of barrel rollers run on a common spherical outer raceway, letting the bearing swivel to absorb misalignment while carrying very high radial load — a cylindrical or tapered roller bearing of the same size fits but cannot self-align, so it is not a substitute. (2) A 'K' suffix is a tapered bore (taper 1:12, or 1:30 on large sizes) for an adapter/withdrawal sleeve; mounting and clearance-setting differ completely from a straight bore, so the two are NOT interchangeable. (3) The 'E' suffix is a reinforced, higher-capacity internal design; roller count and contact geometry also differ by brand, so capacity is not equal at the same size. (4) Radial clearance (C3/C4) is critical — under heavy load and heat the wrong class can seize, and on 'K' bores clearance is set by drive-up on installation. (5) Match cage type (steel/brass/pin). 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 22236?
The 22236 is built to ISO 15 boundary dimensions 180×320×86 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 22236 bearing?
Bore 180 mm, outer diameter 320 mm, B 86 mm (ISO 15).
Is the 22236 interchangeable with a cylindrical or tapered roller bearing?
No. The 22236 shares its 180×320×86 mm envelope, but its two rows of barrel rollers on a spherical raceway let it self-align and carry very high load — a cylindrical or tapered roller bearing of the same size cannot self-align. Also check the bore: a 'K' suffix is a 1:12 tapered bore for a sleeve, not interchangeable with the straight-bore version. Match radial clearance (C3/C4) and cage 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.
