Load condition factor b1 for the steel/PTFE sintered bronze sliding contact surface combination
| Type of load | Factor b1 | Permissible specific bearing load1) |
| - | - | N/mm2 |
| Constant load2) | ||
| Single direction | 1 | up to 100 |
| Variable load | ||
| Alternating direction or pulsating | ||
| magnitude at a frequency | ||
| up to 0,5 Hz | 0,4 | up to 60 |
| over 0,5 up to 5 Hz | 0,2 | up to 40 |
1) Inertia forces should also be taken into consideration.
2) For constant load, oscillating frequencies above 300 min–1 and very short sliding distances, b1 = 1 cannot be used because of possible material fatigue. For additional information, contact the SKF application engineering service.
