| MOUNTING ADVISE | |
| Housing – Ø | Mounting bevel, min. 1,5 mm x 15-45° |
| Shaft | Mounting bevel, 5 mm x 15°, edges rounded |
| Force fitting mandrel | The application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting. |
| MAINTENANCE | GAP-MET®/S is a maintenance-free composite sliding bearing. Oil or grease lubrication is possible. |
| * | Additional sliding bearing alloys are likewise available. |
| ** | Also available with cleaning slots. |
| *** | The above stated material properties are valid for optimal operating conditions. Through changes of the application conditions e.g. higher sliding speed or strain, these values are subject to change. |
