How the 62300-2RS 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); bore code 00 follows the 10/12/15/17 mm exception table, so 62300 fits a 10 mm shaft. The envelope is 10×35×17 mm (0.394×1.378×0.669 in) with a 12.5 mm radial section height, C 8.06 kN, C0 3.4 kN and Pu 0.143 kN. SKF catalogues the sealed execution as 62300-2RS1: 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 15000 r/min, catalogue mass 60 g.
Typical equipment & failure modes
Common applications
- conveyor drives
- fans and blowers
- agricultural equipment
- garden machinery
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
- edge loading from shaft deflection or housing misalignment
- rolling-contact fatigue spalling once the catalogue L10 life is exceeded
Selection pitfalls — read before you substitute
- The fatigue load limit is 0.143 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
- Clearance suffixes follow the seal code in the designation stack (e.g. 62300-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
- Contact seals make 62300-2RS slower than the open 62300 (limiting 15000 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 62300-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Assign interference to the rotating ring: on a conventional shaft-mounted 10 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.
- Deep-groove geometry tolerates only minutes of misalignment; if the 35 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 62300-2RS.
Frequently asked questions
What are the dimensions of 62300-2RS?
The SKF 62300-2RS1 measures 10 mm bore × 35 mm OD × 17 mm width (0.394 × 1.378 × 0.669 in), mass about 60 g. It has two contact rubber seals and a lifetime grease fill.
How does the bore code in 62300 work?
Codes 00–03 follow the exception table (10, 12, 15, 17 mm): 62300 fits a 10 mm shaft. Code × 5 starts at code 04.
What is the speed rating of 62300-2RS?
SKF publishes only the 15000 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 62300-2RS and a same-bore 62-series bearing?
Section height differs: 62300-2RS has a 12.5 mm radial section and C 8.06 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
