Name of the invention Rolling bearing arrangement Description Subject area of the invention The invention relates to the field of high-performance rolling bearings in particular for use in driving gear bearings or main shaft bearings in high speed rotating gas turbines transmissions as well as for example for rotor bearings in helicopters

Predicting time

2019-11-4To create high stiffness for the bearing as well as spindle a preload is usually applied on these bearings There are three main methods for applying preload which are fixed position constant and variable preloads Among them the fixed position preload is often employed on the spindle worked at low speed and heavy load

How to Replace CNC Spindle Bearing Part 4

This Mori Seiki SL25 lathe spindle uses a roller for the #1 bearing and two ACBs mounted directly back to back to handle thrust This design uses a hydraulic nut to maintain bearing preload The lock nut is just for back-up To remove these bearings requires pressurizing the hydraulic nut to about 10 000 PSI DO NOT PRESS THESE OFF

Bearing Arrangement

The bearing arrangement for a rotating component e g a shaft generally requires two bearings to support and locate the component radially and axially relative to the stationary part of the machine Depending on the application load running accuracy and cost the following approaches can be considered: • Locating and non-locating bearing arrangements
