Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| 4211-ATN9 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 55×100×25 mm envelope as SKF 4211 ATN9, but catalogue C/C0 differ (43.6/29 kN vs 44.9/44 kN) — envelope match only after a load check. |

How the 62211-2RS model number is decoded
The 62200-series is the wide-section counterpart of the standard deep-groove family (extra width code built into the designation); the last two digits encode the bore: 62211 carries code 11 = 55 mm (code × 5). The envelope is 55×100×25 mm (2.165×3.937×0.984 in) with a 22.5 mm radial section height, C 43.6 kN, C0 29 kN and Pu 1.25 kN. SKF catalogues the sealed execution as 62211-2RS1: two contact elastomer lips (2RS1/2RSH spelling) over a lifetime grease fill; the lips add drag, and no reference (thermal) speed is published. Limiting speed 4300 r/min, catalogue mass 750 g.
Typical equipment & failure modes
Common applications
- centrifugal and positive-displacement pumps
- material-handling equipment
- industrial fans
- compressor drives
Known failure patterns
- contact-seal lip hardening and pre-grease loss after long high-temperature service
- grease-life expiry inside the sealed-for-life cavity, which has no relubrication path
- 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
- Deep-groove geometry tolerates only minutes of misalignment; if the 100 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 62211-2RS.
- At 55 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.
- Contact seals make 62211-2RS slower than the open 62211 (limiting 4300 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 62211-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Catalogue ratings for 62211-2RS (C 43.6 kN, C0 29 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.
- Mount by heating the inner ring (max 120 °C) — driving 62211-2RS home through the outer ring or balls brinells the raceways.
Frequently asked questions
What are the dimensions of 62211-2RS?
The SKF 62211-2RS1 measures 55 mm bore × 100 mm OD × 25 mm width (2.165 × 3.937 × 0.984 in), mass about 750 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 62211 work?
The final two digits of 62211 are bore code 11, multiplied by 5 to give 55 mm.
How heavy is 62211-2RS?
Catalogue mass is 750 g for 62211-2RS1; seal and cage executions of the same envelope differ by a few grams.
What load can 62211-2RS take?
Catalogue values for 62211-2RS1: dynamic C 43.6 kN, static C0 29 kN, fatigue limit Pu 1.25 kN. Use C in life calculation and C0 for static checks at 55 mm bore.
