Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|

How the 2207-ETN9 model number is decoded
The 22xx series is the wide light-section self-aligning ball bearing (ISO dimension series 22). the last two digits encode the bore: 2207 carries code 07 = 35 mm (code × 5). Envelope 35×72×23 mm (1.378×2.835×0.906 in) with a 18.5 mm radial section height, C 30.2 kN, C0 8.8 kN and Pu 0.455 kN. The open 2207 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 35 mm shaft. Reference (thermal) speed 18000 r/min, limiting speed 12000 r/min, catalogue mass 400 g.
Typical equipment & failure modes
Common applications
- agricultural gearboxes
- textile machinery drives
- industrial fans and blowers
- woodworking machinery
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 35 mm rotating shaft use a k5 seat with an H7 housing; reverse the logic if the outer ring rotates.
- At 35 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 ETN9 suffix on 2207-ETN9 denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 12000 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 2207-ETN9 (2RS1) allows less — the lip seal binds before the spherical raceway does.
- Assign interference to the rotating ring: on a 35 mm rotating shaft use a k5 seat with an H7 housing; reverse the logic if the outer ring rotates.
- Catalogue ratings for 2207-ETN9 (C 30.2 kN, C0 8.8 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 2207-ETN9?
SKF 2207 ETN9 measures 35 mm bore × 72 mm OD × 23 mm width (1.378 × 2.835 × 0.906 in), mass about 400 g. It is open, with no shields or seals.
How does the bore code in 2207 work?
The final two digits of 2207 are bore code 07, multiplied by 5 to give 35 mm.
What load can 2207-ETN9 take?
Catalogue values for 2207 ETN9: dynamic C 30.2 kN, static C0 8.8 kN, fatigue limit Pu 0.455 kN. Use C in life calculation and C0 for static checks at 35 mm bore.
What is the speed rating of 2207-ETN9?
SKF lists a 18000 r/min thermal reference speed and a 12000 r/min mechanical limiting speed for 2207 ETN9; real limits also depend on lubrication and fits.
