Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| 4208-ATN9 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 40×80×23 mm envelope as SKF 4208 ATN9, but catalogue C/C0 differ (30.7/19 kN vs 37.1/32.5 kN) — envelope match only after a load check. |

How the 62208-2RS 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: 62208 carries code 08 = 40 mm (code × 5). The envelope is 40×80×23 mm (1.575×3.15×0.906 in) with a 20.0 mm radial section height, C 30.7 kN, C0 19 kN and Pu 0.8 kN. SKF catalogues the sealed execution as 62208-2RS1: 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 5600 r/min, catalogue mass 470 g.
Typical equipment & failure modes
Common applications
- industrial electric motors
- gearboxes and speed reducers
- centrifugal and positive-displacement pumps
- material-handling equipment
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
- false brinelling from vibration while the shaft stands idle
- fretting corrosion on a creeping shaft or housing seat
Selection pitfalls — read before you substitute
- Mount by heating the inner ring (max 120 °C) — driving 62208-2RS home through the outer ring or balls brinells the raceways.
- Assign interference to the rotating ring: on a conventional shaft-mounted 40 mm position the inner ring rotates, so use a k5/m6 shaft seat with an H7 housing — reverse the logic if the outer ring rotates.
- Contact seals make 62208-2RS slower than the open 62208 (limiting 5600 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 62208-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- At 40 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.
- Catalogue ratings for 62208-2RS (C 30.7 kN, C0 19 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.
Frequently asked questions
What are the dimensions of 62208-2RS?
The SKF 62208-2RS1 measures 40 mm bore × 80 mm OD × 23 mm width (1.575 × 3.15 × 0.906 in), mass about 470 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 62208 work?
The final two digits of 62208 are bore code 08, multiplied by 5 to give 40 mm.
What load can 62208-2RS take?
Catalogue values for 62208-2RS1: dynamic C 30.7 kN, static C0 19 kN, fatigue limit Pu 0.8 kN. Use C in life calculation and C0 for static checks at 40 mm bore.
What is the speed rating of 62208-2RS?
SKF publishes only the 5600 r/min limiting speed for this execution; sealed variants have no thermal reference speed because seal and grease life govern.
