How the 2213-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: 2213 carries code 13 = 65 mm (code × 5). Envelope 65×120×31 mm (2.559×4.724×1.22 in) with a 27.5 mm radial section height, C 57.2 kN, C0 20 kN and Pu 1.02 kN. The open 2213 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 10000 r/min, limiting speed 7000 r/min, catalogue mass 1450 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
- 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
- false brinelling from vibration while the shaft stands idle
- fretting corrosion on a creeping shaft or housing seat
Selection pitfalls — read before you substitute
- Fillet radii must clear the 2213-EKTN9 chamfer so the 31 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- At 65 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.
- On a sleeve-mounted 2213-EKTN9, lock the sleeve against the shaft shoulder; a loose sleeve creeps and frets both the shaft and the bore.
- The EKTN9 suffix on 2213-EKTN9 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 65 mm rotating shaft use a k5 seat with an H7 housing; reverse the logic if the outer ring rotates.
- Catalogue ratings for 2213-EKTN9 (C 57.2 kN, C0 20 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 2213-EKTN9?
SKF 2213 EKTN9 measures 65 mm bore × 120 mm OD × 31 mm width (2.559 × 4.724 × 1.22 in), mass about 1450 g. It is open, with no shields or seals.
How does the bore code in 2213 work?
The final two digits of 2213 are bore code 13, multiplied by 5 to give 65 mm.
Which fits should I use for 2213-EKTN9?
With a rotating inner ring use roughly k5 on the shaft and H7 in the 120 mm housing; reverse the interference if the outer ring rotates.
How heavy is 2213-EKTN9?
Catalogue mass is 1450 g for 2213 EKTN9; seal and cage executions of the same envelope differ by a few grams.
