How the 1214-ETN9 model number is decoded
The 12xx series is the light/normal-section self-aligning ball bearing (ISO dimension series 02). the last two digits encode the bore: 1214 carries code 14 = 70 mm (code × 5). Envelope 70×125×24 mm (2.756×4.921×0.945 in) with a 27.5 mm radial section height, C 35.8 kN, C0 14.6 kN and Pu 0.75 kN. The open 1214 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 70 mm shaft. Reference (thermal) speed 11000 r/min, limiting speed 7000 r/min, catalogue mass 1250 g.
Typical equipment & failure modes
Common applications
- textile machinery drives
- industrial fans and blowers
- woodworking machinery
- pump shafts with mild misalignment
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 0.75 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
- The spherical outer raceway lets 1214-ETN9 tolerate shaft deflection, but it does not increase thrust capacity — combined loads still need an angular-contact or deep-groove bearing.
- The ETN9 suffix on 1214-ETN9 denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 7000 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- Assign interference to the rotating ring: on a 70 mm rotating shaft use a k5 seat with an H7 housing; reverse the logic if the outer ring rotates.
- Catalogue ratings for 1214-ETN9 (C 35.8 kN, C0 14.6 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.
- Mount 1214-ETN9 by heating the inner ring (max 120 °C) on a cylindrical bore — driving it home through the outer ring or balls brinells the raceways.
Frequently asked questions
What are the dimensions of 1214-ETN9?
SKF 1214 ETN9 measures 70 mm bore × 125 mm OD × 24 mm width (2.756 × 4.921 × 0.945 in), mass about 1250 g. It is open, with no shields or seals.
How does the bore code in 1214 work?
The final two digits of 1214 are bore code 14, multiplied by 5 to give 70 mm.
How heavy is 1214-ETN9?
Catalogue mass is 1250 g for 1214 ETN9; seal and cage executions of the same envelope differ by a few grams.
What load can 1214-ETN9 take?
Catalogue values for 1214 ETN9: dynamic C 35.8 kN, static C0 14.6 kN, fatigue limit Pu 0.75 kN. Use C in life calculation and C0 for static checks at 70 mm bore.
