Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| 4307-ATN9 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 35×80×31 mm envelope as SKF 4307 ATN9, but catalogue C/C0 differ (33.2/19 kN vs 50.7/38 kN) — envelope match only after a load check. |

How the 62307-2RS model number is decoded
The 62300-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: 62307 carries code 07 = 35 mm (code × 5). The envelope is 35×80×31 mm (1.378×3.15×1.22 in) with a 22.5 mm radial section height, C 33.2 kN, C0 19 kN and Pu 0.815 kN. SKF catalogues the sealed execution as 62307-2RS1: 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 6000 r/min, catalogue mass 680 g.
Typical equipment & failure modes
Common applications
- machine tool auxiliaries
- agricultural gearboxes
- industrial electric motors
- gearboxes and speed reducers
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 80 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 62307-2RS.
- Clearance suffixes follow the seal code in the designation stack (e.g. 62307-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
- Contact seals make 62307-2RS slower than the open 62307 (limiting 6000 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 62307-2RS 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 62307-2RS home through the outer ring or balls brinells the raceways.
- The fatigue load limit is 0.815 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 62307-2RS?
The SKF 62307-2RS1 measures 35 mm bore × 80 mm OD × 31 mm width (1.378 × 3.15 × 1.22 in), mass about 680 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 62307 work?
The final two digits of 62307 are bore code 07, multiplied by 5 to give 35 mm.
What is the difference between 62307-2RS and a same-bore 62-series bearing?
Section height differs: 62307-2RS has a 22.5 mm radial section and C 33.2 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
Which fits should I use for 62307-2RS?
With a rotating inner ring use roughly k5 on the shaft and H7 in the 80 mm housing; reverse the interference if the outer ring rotates.
