11. This means that herringbone gears can be used in torque gearboxes without requiring a substantial thrust bearing . 12. Unit 7 shut down during an aftershock because the turbine thrust bearing wear trip signal was activated. 13. Forces can be predominately axial ( thrust bearings ), or bending moments perpendicular to the main axis. 14. Some high-precision chucks use ball thrust bearings to reduce friction in the closing mechanism and maximize drilling torque. 15. Thrust surfaces are micro-polished to provide precise surface finishes for smooth engine operation and reduced thrust bearing wear. 16. However helical gears also generate an end-thrust, which then requires a more complicated thrust bearing to support them. 17. For collars that use thrust bearings the frictional loss is negligible and the above equation can be ignored. 18. Common designs are Thrust ball bearings, spherical roller thrust bearings , tapered roller thrust bearings or cylindrical roller thrust bearings. 19. Common designs are Thrust ball bearings, spherical roller thrust bearings, tapered roller thrust bearings or cylindrical roller thrust bearings. 20. Common designs are Thrust ball bearings, spherical roller thrust bearings, tapered roller thrust bearings or cylindrical roller thrust bearings .
