How the 1202-ETN9 model number is decoded
The 12xx series is the light/normal-section self-aligning ball bearing (ISO dimension series 02). bore code 02 follows the 10/12/15/17 mm exception table, so 1202 fits a 15 mm shaft. Envelope 15×35×11 mm (0.591×1.378×0.433 in) with a 10.0 mm radial section height, C 7.41 kN, C0 1.76 kN and Pu 0.09 kN. The open 1202 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 45000 r/min, limiting speed 28000 r/min, catalogue mass 49 g.
Typical equipment & failure modes
Common applications
- light gearbox layshafts
- food-processing conveyors
- small electric motors
- conveyor idler rollers
Known failure patterns
- lubricant starvation where no regreasing interval is maintained
- contamination wear when the open arrangement is used without adequate external sealing
- cage damage from running beyond the limiting speed
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- Assign interference to the rotating ring: on a 15 mm rotating shaft use a j5/k5 seat with an H7 housing; reverse the logic if the outer ring rotates.
- Assign interference to the rotating ring: on a 15 mm rotating shaft use a j5/k5 seat with an H7 housing; reverse the logic if the outer ring rotates.
- The ETN9 suffix on 1202-ETN9 denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 28000 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- Self-aligning ball bearings tolerate up to roughly 2–3° of static misalignment, but the sealed 1202-ETN9 (2RS1) allows less — the lip seal binds before the spherical raceway does.

- Catalogue ratings for 1202-ETN9 (C 7.41 kN, C0 1.76 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.
Frequently asked questions
What are the dimensions of 1202-ETN9?
SKF 1202 ETN9 measures 15 mm bore × 35 mm OD × 11 mm width (0.591 × 1.378 × 0.433 in), mass about 49 g. It is open, with no shields or seals.
How does the bore code in 1202 work?
Codes 00–03 follow the exception table (10, 12, 15, 17 mm): 1202 fits a 15 mm shaft. Code × 5 starts at code 04.
How much misalignment can 1202-ETN9 tolerate?
Self-aligning ball bearings tolerate roughly 2–3° of static misalignment for open executions; sealed 2RS1 variants like 1202-ETN9 allow less (about 1°) because the seal lip binds first.
Can 1202-ETN9 take axial load?
A self-aligning ball bearing can carry some axial load in addition to radial load, but its axial capacity is lower than an angular-contact bearing of the same envelope. Use it where misalignment, not thrust, is the main requirement.
