| PROPERTIES | Excellent sliding- and wear behaviour, for all types of movement, high load capacity, all-round adaptable, maintenance-free. |
| MATERIALS | |
| Support material | Steel tin plated |
| Intermediate layer | Sinterbonze |
| Sliding layer | PTFE |
| MATERIAL PROPERTIES | |
| Specific load capacity static | ≤ 250 [ N/mm² ] |
| Specific load capacity dynamic | ≤ 140 N/mm² at low speeds |
| Sliding speed | ≤ 2,5 [ m/s ] |
| Friction value | 0.03 to 0.25 µ |
| Temperature strain | -200 to +280 [ °C ] |
| Max. Pv - value | 1,8 [N/mm² x m/s] for a short time 3,7 |
| TOLERANCE DETAILS | |
| Housing – Ø | H7 |
| Bushing after mounting | H9 |
| Shaft tolerance | f7 to h8 |
| SHAFT MATERIAL | Steel, hardened or untempered, surface roughness ≤ Rz 2-3 |
| 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 must not contact the sliding surface. |
| MAINTENANCE | TEF-MET® is a dry sliding bearing with PTFE sliding layer. Lubrication is therefore not necessary, but basically possible |
