Reading the number 6200
Every deep groove ball bearing number follows the same pattern: type, dimension series and bore code, then suffixes.
Seals, shields and suffixes
Suffixes add closures and internal clearance. They do not change the boundary dimensions: a sealed and an open bearing of the same number are interchangeable in size.
| Suffix | Meaning | 6200 example |
|---|---|---|
| Open (no suffix) | No seals or shields. Can be relubricated, or run in an oil bath; the housing needs its own seal against dirt. | 6200 |
| Z | One metal shield, on one side only. | 6200-Z |
| ZZ, 2Z | Metal shields on both sides. Non-contact, so low friction; keeps out larger dirt. Usually greased for life. | 6200-ZZ |
| RS | One rubber contact seal, on one side only. | 6200-RS |
| 2RS, 2RS1, 2RSH, 2RSR, DDU, LLU | Rubber contact seals on both sides. Better than shields against fine dirt and splashing water, with a little more friction. Usually greased for life. | 6200-2RS |
| C3 | Radial internal clearance greater than normal (CN). Used with tight shaft or housing fits, or where the inner ring runs hotter than the outer ring. | 6200-2RS C3 |

Seal designs and suffixes vary by maker, size range and product generation, for example contact versus low-friction seals. Confirm the exact designation in the maker's catalogue before ordering.
Same 10 mm bore, other series
Bearings that fit the same shaft. A heavier series carries more load in a bigger housing bore; a thin-section series saves space and weight.

Common questions
What size is a 6200 bearing?
10 mm bore, 30 mm outside diameter and 9 mm wide, which is 0.394 × 1.181 × 0.354 in.
What does 2RS mean on a 6200 bearing?
6200-2RS has rubber contact seals on both sides. 6200-ZZ (also written 6200-2Z) has metal shields on both sides. Both have the same 10 × 30 × 9 mm dimensions.
Is 6200-2RS the same as 6200-ZZ?
They are the same size and interchangeable in a housing. The sealed 6200-2RS keeps out fine dirt and water better; the shielded 6200-ZZ runs with less friction.
What is the SKF equivalent of 6200-2RS?
SKF writes it 6200-2RSH; FAG 6200-2RSR, NSK 6200DDU, NTN 6200LLU and Koyo 6200-2RS. Check the maker's catalogue for the exact seal type.
What does the number 6200 mean?
6 is the deep groove ball bearing type, 2 is the light dimension series, and 00 = 10 mm (codes 00 to 03 are fixed: 10, 12, 15 and 17 mm).
Which bearings have the same bore as 6200?
6800, 6900, 6000, 6300 also have a 10 mm bore, with different outside diameters and widths.
