How the 2202 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: 2202 carries bore code 02 = 15 mm. Codes 00–03 follow the 10/12/15/17 mm exception table rather than code × 5. Outside diameter 35 mm and width 14 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
- small electric motor and fan shafts
- domestic appliance drive shafts
- power tool spindles
- small pump impeller shafts
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- raceway smearing under marginal lubrication at start-up
- fretting corrosion on a loose shaft seat
Selection pitfalls — read before you substitute
- Bore codes 00–03 use the exception table: 2202 fits a 15 mm shaft — the code × 5 mnemonic does not apply below code 04 (it would imply 0 mm for code 00).
- The 22xx wide-section at 15 mm bore adds load capacity through increased 14 mm width; the wider ring needs a wider housing seat and may reduce limiting speed versus a 1202.
- The open 2202 has no lubricant retention: grease escapes and contaminants migrate straight into the 15×35×14 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 2202 units.
- Suffixes stack in a defined order — clearance follows the bore code, e.g. 2202-C3. No clearance suffix means normal CN clearance.
Frequently asked questions
What are the dimensions of a 2202 self-aligning ball bearing?
A 2202 self-aligning ball bearing has a 15 mm bore, 35 mm outer diameter and 14 mm width, per ISO 15 boundary dimensions. This is the cylindrical-bore version; a tapered-bore K variant is available for adapter-sleeve mounting.
Why does 2202 not follow the bore-code × 5 rule?
Codes 00–03 use the exception table (10, 12, 15 and 17 mm): 2202 with code 02 has a 15 mm bore. The code × 5 convention starts at code 04 (20 mm).
What does the open suffix mean on 2202?
A bare 2202 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 15 mm bore?
The 22xx is the wide light section: 35×14 mm with a 10.0 mm radial section at 15 mm bore, wider than a 1202 for higher load capacity at the cost of speed.
