How the 2206-EKTN9 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: 2206 carries code 06 = 30 mm (code × 5). Envelope 30×62×20 mm (1.181×2.441×0.787 in) with a 16.0 mm radial section height, C 23.8 kN, C0 6.7 kN and Pu 0.35 kN. The open 2206 EKTN9 carries no shields or seals and relies on application lubrication and external sealing. The EKTN9 suffix identifies the glass-fibre-reinforced polyamide 66 cage execution. The K suffix marks a 1:12 tapered bore for direct mounting on a tapered shaft or with an adapter sleeve. Reference (thermal) speed 22000 r/min, limiting speed 15000 r/min, catalogue mass 260 g.
Typical equipment & failure modes
Common applications
- fan and blower shafts
- woodworking machine spindles
- light gearbox layshafts
- food-processing conveyors
Known failure patterns
- lubricant starvation where no regreasing interval is maintained
- contamination wear when the open arrangement is used without adequate external sealing
- incorrect sleeve tightening that leaves the tapered bore loose or over-expanded, changing internal clearance
- adapter-sleeve fretting when the sleeve is not locked against the shaft shoulder
- rolling-contact fatigue spalling once the catalogue L10 life is exceeded
- brinelling from static overload or hammer blows during mounting
Selection pitfalls — read before you substitute
- At 30 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.
- Fillet radii must clear the 2206-EKTN9 chamfer so the 20 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- Tighten the adapter sleeve to the SKF-recommended starting clearance, not to feel — an over-tightened sleeve expands the inner ring and removes all internal clearance.
- The EKTN9 suffix on 2206-EKTN9 denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 15000 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- Mount 2206-EKTN9 by heating the inner ring (max 120 °C) on a cylindrical bore — driving it home through the outer ring or balls brinells the raceways.
- The fatigue load limit is 0.35 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
Frequently asked questions
What are the dimensions of 2206-EKTN9?
SKF 2206 EKTN9 measures 30 mm bore × 62 mm OD × 20 mm width (1.181 × 2.441 × 0.787 in), mass about 260 g. It is open, with no shields or seals.
How does the bore code in 2206 work?
The final two digits of 2206 are bore code 06, multiplied by 5 to give 30 mm.
What load can 2206-EKTN9 take?
Catalogue values for 2206 EKTN9: dynamic C 23.8 kN, static C0 6.7 kN, fatigue limit Pu 0.35 kN. Use C in life calculation and C0 for static checks at 30 mm bore.
What is the speed rating of 2206-EKTN9?
SKF lists a 22000 r/min thermal reference speed and a 15000 r/min mechanical limiting speed for 2206 EKTN9; real limits also depend on lubrication and fits.
