Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| 4204-ATN9 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 20×47×18 mm envelope as SKF 4204 ATN9, but catalogue C/C0 differ (12.7/6.55 kN vs 17.8/12.5 kN) — envelope match only after a load check. |

How the 62204-2RS 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: 62204 carries code 04 = 20 mm (code × 5). The envelope is 20×47×18 mm (0.787×1.85×0.709 in) with a 13.5 mm radial section height, C 12.7 kN, C0 6.55 kN and Pu 0.28 kN. SKF catalogues the sealed execution as 62204-2RS1: 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 10000 r/min, catalogue mass 130 g.
Typical equipment & failure modes
Common applications
- fans and blowers
- agricultural equipment
- garden machinery
- textile machines
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
- electrical pitting in VFD-driven motors without shaft grounding
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- Mount by heating the inner ring (max 120 °C) — driving 62204-2RS home through the outer ring or balls brinells the raceways.
- Catalogue ratings for 62204-2RS (C 12.7 kN, C0 6.55 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 62204-2RS slower than the open 62204 (limiting 10000 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 62204-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Do not preload 62204-2RS 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. 62204-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
Frequently asked questions
What are the dimensions of 62204-2RS?
The SKF 62204-2RS1 measures 20 mm bore × 47 mm OD × 18 mm width (0.787 × 1.85 × 0.709 in), mass about 130 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 62204 work?
The final two digits of 62204 are bore code 04, multiplied by 5 to give 20 mm.
What load can 62204-2RS take?
Catalogue values for 62204-2RS1: dynamic C 12.7 kN, static C0 6.55 kN, fatigue limit Pu 0.28 kN. Use C in life calculation and C0 for static checks at 20 mm bore.
What is the speed rating of 62204-2RS?
SKF publishes only the 10000 r/min limiting speed for this execution; sealed variants have no thermal reference speed because seal and grease life govern.
