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 22216 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 22216 encode the bore: code 16 = 80 mm (code × 5 from 04 upward). The ISO 15 envelope is 140 mm outside diameter and 33 mm width — 3.15 × 5.512 × 1.299 in, with a 30.0 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

• The large 80 mm-bore 22216 mounts with real force: use induction heating or hydraulic drive-up on the tapered seat, measure residual clearance in micrometres, and plan lifting fixtures — the 33 mm double-row assembly cannot be drifted into position without brinelling.
• The 222 medium series at 80 mm bore (140×33 mm, 30.0 mm section) is the default general-purpose spherical row; on the same bore a 22316 is larger and wider with far higher load rating — do not swap a failed 22316 down to a 22216 without re-rating life.
• Before fitting 22216, machine the 80 mm shaft seat and 140 mm housing bore with a relief or small fillet so nothing bridges the bearing chamfer; the 33 mm-wide rings only load correctly when the full faces abut, and a large radius pinches the 30.0 mm radial section.
• On a K tapered bore with adapter sleeve, tighten the KM locknut to drive the 22216 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 80 mm seat cannot creep.
• Read the damage pattern on a removed 22216: spalling concentrated on one side of the 140 mm outer race points to misalignment or thrust overload, while uniform roller-end smearing means minimum-load skidding — the two failures demand opposite corrections.
• Self-aligning is not a licence to ignore alignment: 22216 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.
• Spherical rollers need a minimum radial load to keep the rollers driven — as a rule of thumb about 2% of the basic dynamic load rating; an unloaded 22216 on an idler or in a cold-start drive will skid and smear, so add preload, reduce the bearing size or use a sealed grease-filled variant.
