Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| 4205-ATN9 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 25×52×18 mm envelope as SKF 4205 ATN9, but catalogue C/C0 differ (14/7.8 kN vs 19/14.6 kN) — envelope match only after a load check. |

How the 62205-2RS 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: 62205 carries code 05 = 25 mm (code × 5). The envelope is 25×52×18 mm (0.984×2.047×0.709 in) with a 13.5 mm radial section height, C 14 kN, C0 7.8 kN and Pu 0.335 kN. SKF catalogues the sealed execution as 62205-2RS1: 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 8500 r/min, catalogue mass 130 g.
Typical equipment & failure modes
Common applications
- textile machines
- electric motors
- centrifugal pumps
- small gearboxes
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
- fretting corrosion on a creeping shaft or housing seat
- cage damage from running beyond the limiting speed
Selection pitfalls — read before you substitute
- At 25 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.
- Fillet radii must clear the 62205-2RS chamfer so the 18 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- Contact seals make 62205-2RS slower than the open 62205 (limiting 8500 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 62205-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Mount by heating the inner ring (max 120 °C) — driving 62205-2RS home through the outer ring or balls brinells the raceways.
- The fatigue load limit is 0.335 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
Frequently asked questions
What are the dimensions of 62205-2RS?
The SKF 62205-2RS1 measures 25 mm bore × 52 mm OD × 18 mm width (0.984 × 2.047 × 0.709 in), mass about 130 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 62205 work?
The final two digits of 62205 are bore code 05, multiplied by 5 to give 25 mm.
How heavy is 62205-2RS?
Catalogue mass is 130 g for 62205-2RS1; seal and cage executions of the same envelope differ by a few grams.
What load can 62205-2RS take?
Catalogue values for 62205-2RS1: dynamic C 14 kN, static C0 7.8 kN, fatigue limit Pu 0.335 kN. Use C in life calculation and C0 for static checks at 25 mm bore.
