Description
Cylindrical self-lubricating sintered bronze bushings: the porous bronze is impregnated with oil, which rises to the surface during operation and lubricates the shaft. Choose the inner diameter, outer diameter and length from the menus: bores from 3 to 80 mm, outer diameters from 6 to 95 mm, lengths from 4 to 80 mm.
- Borefrom 3 to 80 mm
- Outer diameterfrom 6 to 95 mm
- Lengthfrom 4 to 80 mm
Features
- Porous sintered bronze impregnated with oil: self-lubricating for the whole life of the bushing
- No grease nipple, no maintenance
- Quiet, clean operation
- Ready to press-fit into the housing
Typical applications
Operating conditions
| Loads | Light to medium, without heavy shocks |
|---|---|
| Motion | Continuous or oscillating rotation, low to medium speeds |
| Temperature | Up to about +90 °C (limit of the impregnating oil) |
| Mounting | Press fit into a housing with H7 tolerance; ground shaft with f7 tolerance recommended |
| Avoid | Washing with solvents or degreasers, which remove the oil |
Advantages
- No lubrication needed
- Quiet and inexpensive
- Lots of sizes available
Limitations
- Not suitable for high loads or shocks
- Sensitive to solvents and high temperatures
- For high speeds a rolling bearing is better
Technician's tipMeasure the housing bore and the shaft diameter with a caliper before ordering: the bushing is chosen on those two values, length comes second. Fit it with a press or a drift, not with hammer blows.
