Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| 4210-ATN9 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 50×90×23 mm envelope as SKF 4210 ATN9, but catalogue C/C0 differ (35.1/23.2 kN vs 41/40 kN) — envelope match only after a load check. |

How the 62210-2RS 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: 62210 carries code 10 = 50 mm (code × 5). The envelope is 50×90×23 mm (1.969×3.543×0.906 in) with a 20.0 mm radial section height, C 35.1 kN, C0 23.2 kN and Pu 0.98 kN. SKF catalogues the sealed execution as 62210-2RS1: 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 4800 r/min, catalogue mass 540 g.
Typical equipment & failure modes
Common applications
- compressor drives
- machine tool auxiliaries
- agricultural gearboxes
- industrial electric motors
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
- 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 62210-2RS (C 35.1 kN, C0 23.2 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.
- Catalogue ratings for 62210-2RS (C 35.1 kN, C0 23.2 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.
- Contact seals make 62210-2RS slower than the open 62210 (limiting 4800 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 62210-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Do not preload 62210-2RS to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- Clearance suffixes follow the seal code in the designation stack (e.g. 62210-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
Frequently asked questions
What are the dimensions of 62210-2RS?
The SKF 62210-2RS1 measures 50 mm bore × 90 mm OD × 23 mm width (1.969 × 3.543 × 0.906 in), mass about 540 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 62210 work?
The final two digits of 62210 are bore code 10, multiplied by 5 to give 50 mm.
What is the speed rating of 62210-2RS?
SKF publishes only the 4800 r/min limiting speed for this execution; sealed variants have no thermal reference speed because seal and grease life govern.
What is the difference between 62210-2RS and a same-bore 62-series bearing?
Section height differs: 62210-2RS has a 20 mm radial section and C 35.1 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
