Description
Single-direction thrust ball bearings, series 51300 (FAG). It is the heavy series of single-direction thrust ball bearings, for high axial thrust. This page lists 6 codes, with bores from 25 to 50 mm: choose the code from the menu above.
- TypeSingle-direction thrust ball bearings
- Series51300
- Bore dfrom 25 to 50 mm
- Outer diameter Dfrom 52 to 95 mm
- Codes6
- BrandFAG
Features
- They take axial loads only, in one direction
- Three separable parts: shaft washer, housing washer and cage with balls
- Very small axial height
- Simple mounting, even in tight spaces
Typical applications
Operating conditions
| Loads | Axial only, in one direction; no radial load |
|---|---|
| Speed | Low to medium |
| Minimum load | A minimum thrust is always needed, otherwise the balls skid |
| Lubrication | Grease or oil |
| Temperature | Usually up to about +120 °C |
Advantages
- High axial thrust in very little space
- Simple and separable
- Low cost
Limitations
- No radial load: the shaft must be guided by another bearing
- Limited speeds
- Thrust in one direction only (double-direction bearings are needed for both)
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 orientation: the washer with the smaller bore goes on the (rotating) shaft, the one with the larger bore rests on the fixed housing.
Temperatures and speeds are general guidelines for standard steel bearings: for special conditions ask us for the manufacturer's data.
