How the 22322 model number is decoded
In the 22300-series (ISO 15 dimension series) the leading 2 marks a double-row spherical roller and the last two digits of 22322 encode the bore: code 22 = 110 mm (code × 5 from 04 upward). The ISO 15 envelope is 240 mm outside diameter and 80 mm width — 4.331 × 9.449 × 3.15 in, with a 65.0 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 m6 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
Common applications
- mining and aggregate vibrating screens
- jaw and cone crusher eccentric shafts
- paper machine drying cylinders
- large gear drives and mill pinions
- heavy conveyor drum pulleys
Known failure patterns
- roller smearing and skid marks when the radial load falls below the minimum load needed to drive the roller set
- cage fatigue and fracture on vibratory screens supplied with normal CN clearance instead of a vibratory C4 fit
- fretting corrosion on a tapered-bore sleeve seat when drive-up is insufficient and the inner ring works on the adapter
- lubricant starvation and cage wear where the relubrication interval ignores the slow-speed, dirty operating regime
- water and grit pitting of open bearings in mining and pulping duty after the housing seals degrade
Selection pitfalls — read before you substitute
- The large 110 mm-bore 22322 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 80 mm double-row assembly cannot be drifted into position without brinelling.
- The 223 heavy wide series at 110 mm bore (240×80 mm) is selected for shock and high radial load in screens and crushers; its 65.0 mm section needs correspondingly wider shaft and housing shoulders and a stiffer shaft than a 22222 on the same journal.
- Before fitting 22322, machine the 110 mm shaft seat and 240 mm housing bore with a relief or small fillet so nothing bridges the bearing chamfer; the 80 mm-wide rings only load correctly when the full faces abut, and a large radius pinches the 65.0 mm radial section.
- On a K tapered bore with adapter sleeve, tighten the KM locknut to drive the 22322 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 110 mm seat cannot creep.
- When reusing a sleeve-mounted 22322, inspect the adapter and lock parts together with the bearing: a stretched sleeve or a bent lockwasher tab that let the inner ring creep on the 110 mm journal must be replaced, or the new bearing frets the same seat.
- In a classic two-bearing arrangement the 22322 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: 22322 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.
Frequently asked questions
What are the dimensions of a 22322 spherical roller bearing?
A 22322 double-row spherical roller bearing per ISO 15 has a 110 mm bore, 240 mm outer diameter and 80 mm width (4.331 × 9.449 × 3.15 in), a 65.0 mm radial section and roughly 14587 g geometry-based estimated mass; catalogue masses vary with cage and design.
How does the 22322 bore code work?
The leading 2 in 22322 denotes a double-row spherical roller, the middle digits give the ISO 15 dimension series, and the last two digits are bore code 22: 22 × 5 = 110 mm. The 240 mm OD and 80 mm width come from the dimension series (22300), not from the bore code alone.
How much misalignment can a 22322 accommodate?
Thanks to the sphered outer ring raceway, 22322 normally accommodates angular misalignment of around 1° under load (up to about 2° in favourable, lightly loaded conditions); the permissible value is smaller under full load and depends on clearance and cage design, so check the catalogue figure for the actual duty.
What is the difference between 22322 and 22322K?
The plain 22322 has a cylindrical bore for a straight shaft seat. The K suffix denotes a 1:12 tapered bore, normally mounted on an H3xx adapter sleeve over a commercial shaft (or directly on a tapered journal); the bearing is driven up the sleeve to a specified residual clearance and locked with a KM nut and tab washer.
Should the 22322 be ordered with CN, C3 or C4 clearance?
Use C3 as the usual default when the rotating inner ring has an interference fit, because the fit plus thermal expansion reduces residual play; choose C4 (often with a vibratory cage design) for screens and feeders; order CN mainly for loose fits on stationary shafts or split housings. A W33 outer-ring lubrication groove is a separate, commonly combined option.
