How the 13030 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: 13030 carries code 30 = 150 mm (code × 5). Envelope 150×225×56 mm (5.906×8.858×2.205 in) with a 37.5 mm radial section height, C 57.2 kN, C0 23.6 kN and Pu 0.88 kN. The open 13030 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 bore is cylindrical (straight), for a press-fit on a 150 mm shaft. Reference (thermal) speed 5600 r/min, limiting speed 3400 r/min, catalogue mass 7500 g.
Typical equipment & failure modes
Common applications
- crusher feeders
- large industrial gearboxes
- material-handling winches
- large conveyor drives
Known failure patterns
- contamination wear when the open arrangement is used without adequate external sealing
- lubricant starvation where no regreasing interval is maintained
- raceway smearing under marginal lubrication at start-up
- electrical pitting in VFD-driven motors without shaft grounding
Selection pitfalls — read before you substitute
- Catalogue ratings for 13030 (C 57.2 kN, C0 23.6 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.
- Self-aligning ball bearings tolerate up to roughly 2–3° of static misalignment, but the sealed 13030 (2RS1) allows less — the lip seal binds before the spherical raceway does.
- The suffix on 13030 denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 3400 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- Mount 13030 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 0.88 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
- At 150 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.
Frequently asked questions
What are the dimensions of 13030?
SKF 13030 measures 150 mm bore × 225 mm OD × 56 mm width (5.906 × 8.858 × 2.205 in), mass about 7500 g. It is open, with no shields or seals.
How does the bore code in 13030 work?
The final two digits of 13030 are bore code 30, multiplied by 5 to give 150 mm.
How heavy is 13030?
Catalogue mass is 7500 g for 13030; seal and cage executions of the same envelope differ by a few grams.
What load can 13030 take?
Catalogue values for 13030: dynamic C 57.2 kN, static C0 23.6 kN, fatigue limit Pu 0.88 kN. Use C in life calculation and C0 for static checks at 150 mm bore.
