How the 2213-E-2RS1KTN9 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: 2213 carries code 13 = 65 mm (code × 5). Envelope 65×120×31 mm (2.559×4.724×1.22 in) with a 27.5 mm radial section height, C 35.1 kN, C0 14 kN and Pu 0.72 kN. SKF spells the sealed execution 2213 E-2RS1KTN9 (suffix 2RS1): two contact elastomer lips over a lifetime grease fill; the lips add drag, and no thermal reference speed is published. The E-2RS1KTN9 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. Limiting speed 3600 r/min, catalogue mass 1400 g.
Typical equipment & failure modes
Common applications
- woodworking machinery
- pump shafts with mild misalignment
- material-handling equipment
- industrial electric motors
Known failure patterns
- contact-seal lip hardening and grease-life expiry after long high-temperature service
- fine dust or moisture passing a worn seal lip in dirty or wet duty
- adapter-sleeve fretting when the sleeve is not locked against the shaft shoulder
- incorrect sleeve tightening that leaves the tapered bore loose or over-expanded, changing internal clearance
- 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 2213-E-2RS1KTN9 (C 35.1 kN, C0 14 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 2213-E-2RS1KTN9 (2RS1) allows less — the lip seal binds before the spherical raceway does.
- Sealed self-aligning bearings tolerate less misalignment than open ones: keep static misalignment under roughly 1° on 2213-E-2RS1KTN9 to avoid seal-lip binding.
- The K suffix means a 1:12 tapered bore: 2213-E-2RS1KTN9 is not a drop-in for the straight-bore version — it needs a tapered shaft or an H-series adapter sleeve.
- The E-2RS1KTN9 suffix on 2213-E-2RS1KTN9 denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 3600 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- At 65 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 2213-E-2RS1KTN9?
SKF 2213 E-2RS1KTN9 measures 65 mm bore × 120 mm OD × 31 mm width (2.559 × 4.724 × 1.22 in), mass about 1400 g. It has two contact rubber seals (2RS1) and a lifetime grease fill.
How does the bore code in 2213 work?
The final two digits of 2213 are bore code 13, multiplied by 5 to give 65 mm.
How heavy is 2213-E-2RS1KTN9?
Catalogue mass is 1400 g for 2213 E-2RS1KTN9; seal and cage executions of the same envelope differ by a few grams.
What load can 2213-E-2RS1KTN9 take?
Catalogue values for 2213 E-2RS1KTN9: dynamic C 35.1 kN, static C0 14 kN, fatigue limit Pu 0.72 kN. Use C in life calculation and C0 for static checks at 65 mm bore.
