How the 2222 model number is decoded
In the 2200-series (ISO 15 dimension series) the leading digits 22 mark a double-row self-aligning ball bearing and the last two digits encode the bore: 2222 carries bore code 22 = 110 mm. Outside diameter 200 mm and width 53 mm follow the ISO 15 general plan. The cylindrical bore fits directly on a machined shaft seat; a tapered-bore K variant is available for adapter-sleeve mounting. Two rows of balls run on a common sphered outer raceway, allowing the inner ring to pivot and compensate for shaft deflection or housing misalignment.
Typical equipment & failure modes
Common applications
- industrial fan and blower rotors
- hoist, winch and crane drums
- heavy conveyor drive shafts
- pulp, paper and steel mill machinery
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- rolling-contact fatigue spalling after the rated L10 life is exceeded
- cage wear or fracture from sustained vibration or shock loading
Selection pitfalls — read before you substitute
- Mount this 110 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 22xx wide-section at 110 mm bore adds load capacity through increased 53 mm width; the wider ring needs a wider housing seat and may reduce limiting speed versus a 1222.
- The open 2222 has no lubricant retention: grease escapes and contaminants migrate straight into the 110×200×53 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 2200-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 2222 units.
- Shaft and housing fillets must clear the bearing chamfer so the 53 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
Frequently asked questions
What are the dimensions of a 2222 self-aligning ball bearing?
A 2222 self-aligning ball bearing has a 110 mm bore, 200 mm outer diameter and 53 mm width, per ISO 15 boundary dimensions. This is the cylindrical-bore version; a tapered-bore K variant is available for adapter-sleeve mounting.
How does the 2222 bore code work?
The last two digits of 2222 are bore code 22, giving 22 × 5 = 110 mm bore. The 200 mm outside diameter and 53 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the open suffix mean on 2222?
A bare 2222 designation means open: no shields or seals, normal CN radial clearance and P0 normal tolerance unless further suffixes are ordered. The application must supply and retain the lubrication.
How does the 2200 compare with other self-aligning series at the same 110 mm bore?
The 22xx is the wide light section: 200×53 mm with a 45.0 mm radial section at 110 mm bore, wider than a 1222 for higher load capacity at the cost of speed.
