6200 Bearing Dimensions and SKF Specifications
10 × 30 × 9 mm — single-row deep groove ball bearing
SKF Open 6200 Specifications
| Property | SKF catalog value |
|---|---|
| Bore diameter (d) | 10 mm |
| Outside diameter (D) | 30 mm |
| Width (B) | 9 mm |
| Basic dynamic load rating (C) | 5.4 kN |
| Basic static load rating (C0) | 2.36 kN |
| Reference speed | 56,000 r/min |
| Limiting speed | 36,000 r/min |
These values apply to the SKF open 6200 designation in the cited catalog. Reference speed and limiting speed are separate measures. Neither is a universal application speed recommendation. Sealed, shielded and special internal designs require their own specifications.

NSK Open 6200 Specifications
| Property | NSK open 6200 |
|---|---|
| Boundary dimensions | 10 × 30 × 9 mm |
| Basic dynamic load rating | 5.6 kN |
| Basic static load rating | 2.39 kN |
| Grease lubrication speed | 28,000 min⁻¹ |
| Oil-bath lubrication speed | 34,000 min⁻¹ |
| Radial internal clearance | CN |
Source: NSK 6200 online catalogue, checked 12 October 2026. These values apply to the sourced open bearing. NSK lubrication-specific speeds and SKF reference/limiting speeds are different measures; dimensional agreement does not establish replacement suitability.
Replacement Candidates and Evidence
SKF and NSK open 6200 boundary dimensions are sourced above. Other brand designations remain inherited candidates awaiting source review. A shared base number does not establish interchangeability or supplier stock availability.
| Manufacturer | Candidate designation | Evidence |
|---|---|---|
| FAG (Schaeffler) | 6200 | Unverified candidate |
| NSK | 6200 | Open-bearing dimensions sourced; replacement not established |
| Timken | 6200 | Unverified candidate |
| NTN | 6200 | Unverified candidate |
| Koyo (JTEKT) | 6200 | Unverified candidate |
| NACHI | 6200 | Unverified candidate |
Before Selecting a Replacement
Record the complete marking on the original bearing. Verify bore, outside diameter and width, then compare seals or shields, internal clearance, cage, tolerances, lubrication and load and speed requirements against the exact manufacturer variant and equipment specification.
C3 describes internal clearance; it is not a quality grade. Closure suffixes differ between manufacturers. Do not infer the complete configuration from the base number alone.
Preserve prefixes, suffixes, slashes and hyphens when searching. Missing information remains unknown until sourced.

Reading the Full 6200 Designation
Keep closure and clearance separate. NSK uses Z/ZZ for shields and several seal families, including DDU and VV. A generic 2RS marking does not identify the exact seal design; use the manufacturer product record.
CN is Normal radial internal clearance; C3 is greater than Normal and does not change the nominal boundary dimensions. Choose the clearance specified for the equipment and operating conditions, rather than treating C3 as an upgrade.
