How the 1319-K model number is decoded
The 13xx series is the medium/normal-section self-aligning ball bearing (ISO dimension series 03). the last two digits encode the bore: 1319 carries code 19 = 95 mm (code × 5). Envelope 95×200×45 mm (3.74×7.874×1.772 in) with a 52.5 mm radial section height, C 133 kN, C0 51 kN and Pu 2.16 kN. The open 1319 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 6300 r/min, limiting speed 4300 r/min, catalogue mass 6700 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
- cage damage from running beyond the limiting speed
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- Assign interference to the rotating ring: on a 95 mm rotating shaft use a k5 seat with an H7 housing; reverse the logic if the outer ring rotates.
- Fillet radii must clear the 1319-K chamfer so the 45 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- On a sleeve-mounted 1319-K, lock the sleeve against the shaft shoulder; a loose sleeve creeps and frets both the shaft and the bore.
- The suffix on 1319-K denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 4300 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- Fillet radii must clear the 1319-K chamfer so the 45 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- Self-aligning ball bearings tolerate up to roughly 2–3° of static misalignment, but the sealed 1319-K (2RS1) allows less — the lip seal binds before the spherical raceway does.
Frequently asked questions
What are the dimensions of 1319-K?
SKF 1319 K measures 95 mm bore × 200 mm OD × 45 mm width (3.74 × 7.874 × 1.772 in), mass about 6700 g. It is open, with no shields or seals.
How does the bore code in 1319 work?
The final two digits of 1319 are bore code 19, multiplied by 5 to give 95 mm.
Which fits should I use for 1319-K?
With a rotating inner ring use roughly k5 on the shaft and H7 in the 200 mm housing; reverse the interference if the outer ring rotates.
How heavy is 1319-K?
Catalogue mass is 6700 g for 1319 K; seal and cage executions of the same envelope differ by a few grams.
