TECHNICAL DATA POM-MET®
- Wrapped composite sliding bearing steel / POM, with lubrication pockets.
- Low-maintenance
- DIN 1494 / ISO 3547
- All special designs are produced at short notice!
- Additional lubrication slots or lubrication drills on demand!
- Cylindrical bushings, thrust washer and strips are standard fabrication.
| PROPERTIES | Suitable for grease or oil lubrication and all kinds of movements, good load capacity, robust and insensible to dirt. |
| MATERIALS | |
| Support material | Steel copper plated / tin plated |
| Intermediate layer | Sintered bronze |
| Sliding layer | Acetal resin / POM |
| MATERIAL PROPERTIES | |
| Specific load capacity static | ≤ 250 [ N/mm² ] |
| Specific load capacity dynamic | ≤ 140 [ N/mm² ] at low sliding speeds |
| Sliding speed | ≤ 2,5 [ m/s ] |
| Friction value | 0,04 to 0,12 [ µ ] dependings on lubrication |
| Temperature strain | -40 to +130 [ °C ] |
| Max. Pv - value | 2,8 [ N/mm² x m/s ] |
| TOLERANCE DETAILS | |
| Housing – Ø | H7 |
| Bushing after mounting | In the range of D |
| Shaft tolerance | h8 |
| SHAFT MATERIAL | Steel, hardened or untempered, surface roughness ≤ Rz 4-6 |
| 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. Maybe grease lubrication of the outer surface is necessary when mounting. |
| Stick in | Adhesive should not contact the sliding surface. |
| MAINTENANCE | POM-MET® is a low-maintenace composite sliding bearing with a POM coating. Primary lubrication is necessary. Oil or grease lubrication is possible. Because of lubrication pockets lubrication clearances are reduced to a minimum! |
