How the 2217-K 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: 2217 carries code 17 = 85 mm (code × 5). Envelope 85×150×36 mm (3.346×5.906×1.417 in) with a 32.5 mm radial section height, C 58.5 kN, C0 23.6 kN and Pu 1.12 kN. The open 2217 K carries no shields or seals and relies on application lubrication and external sealing. The 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 8000 r/min, limiting speed 5600 r/min, catalogue mass 2500 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 2217-K chamfer so the 36 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- At 85 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 2217-K, lock the sleeve against the shaft shoulder; a loose sleeve creeps and frets both the shaft and the bore.
- The suffix on 2217-K denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 5600 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- At 85 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 spherical outer raceway lets 2217-K tolerate shaft deflection, but it does not increase thrust capacity — combined loads still need an angular-contact or deep-groove bearing.
Frequently asked questions
What are the dimensions of 2217-K?
SKF 2217 K measures 85 mm bore × 150 mm OD × 36 mm width (3.346 × 5.906 × 1.417 in), mass about 2500 g. It is open, with no shields or seals.
How does the bore code in 2217 work?
The final two digits of 2217 are bore code 17, multiplied by 5 to give 85 mm.
Which fits should I use for 2217-K?
With a rotating inner ring use roughly k5 on the shaft and H7 in the 150 mm housing; reverse the interference if the outer ring rotates.
How heavy is 2217-K?
Catalogue mass is 2500 g for 2217 K; seal and cage executions of the same envelope differ by a few grams.
