Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| 2202 | NTN | partial Main dimensions match; tolerances, seals or internal clearance differ. | NTN bearing 2202S on the same 15×35×14 mm envelope, but catalogue C/C0 differ (8.71/2.04 kN vs 7.8/1.85 kN) — envelope interchange only after a load check. |
| 2202-E-2RS1TN9 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 15×35×14 mm envelope, but catalogue C/C0 differ between executions (8.71/2.04 kN vs 7.41/1.76 kN) — boundary dimensions match, not a load-rating equivalent. |

How the 2202-ETN9 model number is decoded
The 22xx series is the wide light-section self-aligning ball bearing (ISO dimension series 22). bore code 02 follows the 10/12/15/17 mm exception table, so 2202 fits a 15 mm shaft. Envelope 15×35×14 mm (0.591×1.378×0.551 in) with a 10.0 mm radial section height, C 8.71 kN, C0 2.04 kN and Pu 0.11 kN. The open 2202 ETN9 carries no shields or seals and relies on application lubrication and external sealing. The ETN9 suffix identifies the glass-fibre-reinforced polyamide 66 cage execution. The bore is cylindrical (straight), for a press-fit on a 15 mm shaft. Reference (thermal) speed 38000 r/min, limiting speed 26000 r/min, catalogue mass 60 g.
Typical equipment & failure modes
Common applications
- food-processing conveyors
- small electric motors
- conveyor idler rollers
- agricultural machinery shafts
Known failure patterns
- contamination wear when the open arrangement is used without adequate external sealing
- lubricant starvation where no regreasing interval is maintained
- excessive misalignment loading one ball row heavily and spalling it early
- rolling-contact fatigue spalling once the catalogue L10 life is exceeded
Selection pitfalls — read before you substitute
- The fatigue load limit is 0.11 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
- Catalogue ratings for 2202-ETN9 (C 8.71 kN, C0 2.04 kN) are SKF figures from PUB BU/P1 17000; geometry revisions can change ratings without changing the designation, so keep the catalogue edition with the specification.
- The ETN9 suffix on 2202-ETN9 denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 26000 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- At 15 mm bore, C3 clearance is the safe choice when interference fits plus temperature rise consume the CN clearance; a hot tight bearing with no residual clearance fails fast.
- The spherical outer raceway lets 2202-ETN9 tolerate shaft deflection, but it does not increase thrust capacity — combined loads still need an angular-contact or deep-groove bearing.
- Fillet radii must clear the 2202-ETN9 chamfer so the 14 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
Frequently asked questions
What are the dimensions of 2202-ETN9?
SKF 2202 ETN9 measures 15 mm bore × 35 mm OD × 14 mm width (0.591 × 1.378 × 0.551 in), mass about 60 g. It is open, with no shields or seals.
How does the bore code in 2202 work?
Codes 00–03 follow the exception table (10, 12, 15, 17 mm): 2202 fits a 15 mm shaft. Code × 5 starts at code 04.
What is the speed rating of 2202-ETN9?
SKF lists a 38000 r/min thermal reference speed and a 26000 r/min mechanical limiting speed for 2202 ETN9; real limits also depend on lubrication and fits.
How much misalignment can 2202-ETN9 tolerate?
Self-aligning ball bearings tolerate roughly 2–3° of static misalignment for open executions; sealed 2RS1 variants like 2202-ETN9 allow less (about 1°) because the seal lip binds first.
