How the 2219-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: 2219 carries code 19 = 95 mm (code × 5). Envelope 95×170×43 mm (3.74×6.693×1.693 in) with a 37.5 mm radial section height, C 83.2 kN, C0 34.5 kN and Pu 1.53 kN. The open 2219 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 7000 r/min, limiting speed 5000 r/min, catalogue mass 4100 g.
Typical equipment & failure modes
Common applications
- industrial fans and blowers
- woodworking machinery
- pump shafts with mild misalignment
- material-handling equipment
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 95 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 2219-K chamfer so the 43 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- The K suffix means a 1:12 tapered bore: 2219-K is not a drop-in for the straight-bore version — it needs a tapered shaft or an H-series adapter sleeve.
- The suffix on 2219-K denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 5000 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- Mount 2219-K 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 1.53 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 2219-K?
SKF 2219 K measures 95 mm bore × 170 mm OD × 43 mm width (3.74 × 6.693 × 1.693 in), mass about 4100 g. It is open, with no shields or seals.
How does the bore code in 2219 work?
The final two digits of 2219 are bore code 19, multiplied by 5 to give 95 mm.
How much misalignment can 2219-K tolerate?
Self-aligning ball bearings tolerate roughly 2–3° of static misalignment for open executions; sealed 2RS1 variants like 2219-K allow less (about 1°) because the seal lip binds first.
Can 2219-K take axial load?
A self-aligning ball bearing can carry some axial load in addition to radial load, but its axial capacity is lower than an angular-contact bearing of the same envelope. Use it where misalignment, not thrust, is the main requirement.
