Description
Single-row deep groove ball bearings, series 6200 (FAG · ECO line). It is by far the most widespread series, the best compromise between size and load capacity, found in electric motors, pumps, gearboxes and machines of every kind. This page lists 86 codes, with bores from 10 to 50 mm: choose the code from the menu above.
- TypeSingle-row deep groove ball bearings
- Series6200
- Bore dfrom 10 to 50 mm
- Outer diameter Dfrom 30 to 90 mm
- Codes86
- BrandFAG · ECO line
Features
- They take radial loads and moderate axial loads in both directions
- Low friction and high speeds, quiet running
- ISO standard dimensions: interchangeable between brands
- Open, shielded (ZZ/2Z) or rubber-sealed (2RS) versions lubricated for life
Typical applications
Operating conditions
| Loads | Radial; moderate axial in both directions |
|---|---|
| Speed | High (open versions are the fastest) |
| Misalignment | Poorly tolerated: shaft and housing must be aligned |
| Lubrication | Grease (for life in ZZ and 2RS versions) or oil |
| Temperature | Usually up to about +120 °C; with rubber seals the limit is set by the seal (about +100 °C) |
Advantages
- The most versatile and easiest bearing to find
- Suitable for high speeds
- Low maintenance in shielded or sealed versions
- Low cost
Limitations
- Only moderate axial loads
- Does not compensate for misalignment between shaft and housing
- For very heavy radial loads or shocks, a roller bearing is better
How to read the code
| 2RS | rubber seals on both sides: protection against dust and splashes, lubricated for life |
|---|---|
| ZZ / 2Z | metal shields on both sides: protection against dust, minimal friction, lubricated for life |
| C3 | increased internal radial clearance: for tight fits or high temperatures (typical of electric motors) |
| FAG | Schaeffler FAG brand |
| ECO | economy line alternative to FAG, for less demanding uses |
Available codes
The d × D × B dimensions (bore, outer diameter, width) of each code appear in the "Sizes" menu; variants with a suffix (2RS, ZZ, C3…) are listed in the series menu.
Technician's tipTo replace a bearing, all you need is the code engraved on the outer ring: the first digits indicate type and series, the last two the bore (from 04 upwards, multiplied by 5: 6205 = 25 mm bore). If the old one was 2RS or ZZ, take the same protection.
Temperatures and speeds are general guidelines for standard steel bearings: for special conditions ask us for the manufacturer's data.
