Standard-interchange bearing: dimensions per ISO 15; CN clearance, P0 tolerance and a stamped-steel cage are catalogue defaults unless the supplier states otherwise, and mass is a geometry-derived estimate.

How the 22207 model number is decoded

In the 22200-series (ISO 15 dimension series) the leading 2 marks a double-row spherical roller and the last two digits of 22207 encode the bore: code 07 = 35 mm (code × 5 from 04 upward). The ISO 15 envelope is 72 mm outside diameter and 23 mm width — 1.378 × 2.835 × 0.906 in, with a 18.5 mm radial section height. Two rows of symmetrical barrel rollers on a common sphered outer raceway self-align to shaft deflection while carrying heavy radial load and bidirectional axial load. Typical catalogue practice for a rotating inner ring is a k5 shaft seat, H7 housing and C3 internal clearance; K variants use a 1:12 tapered bore on an adapter sleeve — verify against the mounting arrangement.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 35 mm bore the small 22207 is often delivered sealed (2CS) and grease-filled for life in conveyor idlers — do not add grease nipples to a sealed row; for the open version, keep housing seals effective because the 23 mm cavity holds little oil reserve.
• The 222 medium series at 35 mm bore (72×23 mm, 18.5 mm section) is the default general-purpose spherical row; on the same bore a 22307 is larger and wider with far higher load rating — do not swap a failed 22307 down to a 22207 without re-rating life.
• Before fitting 22207, machine the 35 mm shaft seat and 72 mm housing bore with a relief or small fillet so nothing bridges the bearing chamfer; the 23 mm-wide rings only load correctly when the full faces abut, and a large radius pinches the 18.5 mm radial section.
• On a K tapered bore with adapter sleeve, tighten the KM locknut to drive the 22207 up the sleeve, rotating the inner ring, and stop on residual clearance — measured with feelers at the unloaded rollers — not on torque alone; then lock the tab washer so the 35 mm seat cannot creep.
• Read the damage pattern on a removed 22207: spalling concentrated on one side of the 72 mm outer race points to misalignment or thrust overload, while uniform roller-end smearing means minimum-load skidding — the two failures demand opposite corrections.
• In a classic two-bearing arrangement the 22207 often serves as the non-locating (floating) bearing, taking radial load while the housing bore lets it drift; it can locate axially in both directions, but sustained pure thrust beyond the catalogue limit unloads one roller row.
• Self-aligning is not a licence to ignore alignment: 22207 accommodates typically around 1° of angular misalignment under normal load (roughly 2° only in favourable, light-load conditions) — the exact figure falls with load, so check the catalogue value rather than designing to the maximum.
