WebThe 10-percent life of the system would be calculated to be 1,124 hours. This means if you distributed 1,000 gearboxes and they were all operated at maximum torque for 1,124 hours, 100 gearboxes would have at least one bearing failure. The question then becomes how long could you operate the gearbox at this condition without a failure. WebMar 10, 2024 · For a linear ball bearing ( p = 3) with an applied load (F) of 1000 N and a load capacity (C) of 1320 N, the L 2m life (98% reliability) will be: Similarly, to determine the required dynamic load capacity that will allow a linear ball bearing with a 1000 N load to travel 85,000 km, with 98% reliability, the equation can be rearranged as:
