Description
Double-row deep groove ball bearings, series 4300 (FAG). It is the medium series of double-row deep groove ball bearings, for high radial loads in little space. This page lists 6 codes, with bores from 15 to 40 mm: choose the code from the menu above.
- TypeDouble-row deep groove ball bearings
- Series4300
- Bore dfrom 15 to 40 mm
- Outer diameter Dfrom 42 to 90 mm
- Codes6
- BrandFAG
Features
- Two rows of balls side by side: more radial load capacity than a single-row bearing with the same bore
- Also take moderate axial loads
- Greater axial width than a single-row bearing
Typical applications
Operating conditions
| Loads | High radial; moderate axial |
|---|---|
| Speed | Medium to high |
| Misalignment | Poorly tolerated |
| Lubrication | Grease or oil |
| Temperature | Usually up to about +120 °C |
Advantages
- More radial load for the same bore
- Replaces two side-by-side bearings with a single part
Limitations
- Requires good alignment between shaft and housing
- Slower than a single-row bearing
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 tipCheck the alignment of the housings before fitting it: two rows of balls tolerate a tilted shaft poorly. If the shaft flexes, consider a self-aligning bearing.
Temperatures and speeds are general guidelines for standard steel bearings: for special conditions ask us for the manufacturer's data.
