Description
Flanged self-lubricating sintered bronze bushing: bore 32 mm, outer diameter 42 mm, flange Ø 48 × 5 mm, overall length 32 mm. The porous bronze is impregnated with oil, which rises to the surface during operation and lubricates the shaft: no grease nipples, no maintenance.
- Bore d132 mm
- Outside d242 mm
- Flange d348 mm
- Flange thickness b25 mm
- Length b132 mm
Features
- Porous sintered bronze impregnated with oil: self-lubricating for the whole life of the bushing
- The flange acts as a stop: it locates the bushing in the housing and takes small axial loads
- Quiet operation, with no grease dripping or collecting dirt
- 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
- The flange makes mounting easier and acts as a stop
Limitations
- Not suitable for high loads or shocks
- Sensitive to solvents and high temperatures
- For high speeds a rolling bearing is better
How to read the size
The code 32x42x48x5x32 follows the order d1 × d2 × d3 × b2 × b1: bore, outer diameter, flange diameter, flange thickness, overall length (including flange).
Technician's tipPress the bushing in with a press or a drift that bears on the whole flange, never with direct hammer blows: sintered bronze is porous and deforms. After fitting, check that the shaft turns freely.
