Description
Single-row tapered roller bearings, series 30300 (FAG). It is the medium series of tapered roller bearings, with a taller section than the 30200, for higher loads with the same bore. This page lists 8 codes, with bores from 17 to 50 mm: choose the code from the menu above.
- TypeSingle-row tapered roller bearings
- Series30300
- Bore dfrom 17 to 50 mm
- Outer diameter Dfrom 47 to 110 mm
- Codes8
- BrandFAG
Features
- Tapered rollers: they take high radial loads and axial loads in one direction together
- Separable: cone (inner ring with rollers and cage) and cup (outer ring) are mounted separately
- They are used in opposed pairs, adjusting clearance or preload during mounting
- High shaft rigidity
Typical applications
Operating conditions
| Loads | High radial + axial in one direction (in pairs: in both) |
|---|---|
| Speed | Medium |
| Misalignment | Not tolerated |
| Mounting | In pairs, with clearance or preload adjustment |
| Lubrication | Grease or oil |
| Temperature | Usually up to about +120 °C |
Advantages
- High combined load capacity
- High rigidity
- Separable: easier mounting and inspection
Limitations
- Clearance must be adjusted during mounting
- A single bearing takes thrust in one direction only
- Lower speeds than ball bearings
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 tipAlways replace cone and cup together, and set the axial clearance as specified by the machine manufacturer: too tight runs hot, too loose knocks.
Temperatures and speeds are general guidelines for standard steel bearings: for special conditions ask us for the manufacturer's data.
