How the 13036 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: 13036 carries code 36 = 180 mm (code × 5). Envelope 180×280×74 mm (7.087×11.024×2.913 in) with a 50.0 mm radial section height, C 95.6 kN, C0 40 kN and Pu 1.34 kN. The open 13036 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 180 mm shaft. Reference (thermal) speed 4500 r/min, limiting speed 2800 r/min, catalogue mass 16000 g.
Typical equipment & failure modes
Common applications
- paper-machine rolls
- marine deck machinery
- crusher feeders
- large industrial gearboxes
Known failure patterns
- contamination wear when the open arrangement is used without adequate external sealing
- lubricant starvation where no regreasing interval is maintained
- fretting corrosion on a creeping shaft or housing seat
- cage damage from running beyond the limiting speed
Selection pitfalls — read before you substitute
- Self-aligning ball bearings tolerate up to roughly 2–3° of static misalignment, but the sealed 13036 (2RS1) allows less — the lip seal binds before the spherical raceway does.
- The spherical outer raceway lets 13036 tolerate shaft deflection, but it does not increase thrust capacity — combined loads still need an angular-contact or deep-groove bearing.
- The suffix on 13036 denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 2800 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- At 180 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 13036 tolerate shaft deflection, but it does not increase thrust capacity — combined loads still need an angular-contact or deep-groove bearing.
- Fillet radii must clear the 13036 chamfer so the 74 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
Frequently asked questions
What are the dimensions of 13036?
SKF 13036 measures 180 mm bore × 280 mm OD × 74 mm width (7.087 × 11.024 × 2.913 in), mass about 16000 g. It is open, with no shields or seals.
How does the bore code in 13036 work?
The final two digits of 13036 are bore code 36, multiplied by 5 to give 180 mm.
What is the speed rating of 13036?
SKF lists a 4500 r/min thermal reference speed and a 2800 r/min mechanical limiting speed for 13036; real limits also depend on lubrication and fits.
How much misalignment can 13036 tolerate?
Self-aligning ball bearings tolerate roughly 2–3° of static misalignment for open executions; sealed 2RS1 variants like 13036 allow less (about 1°) because the seal lip binds first.
