Description
Spherical roller bearings in plummer blocks are used widely in larger slow speed applications such as conveyor main pulleys bearings and slow speed drive shafts. Usually when you look at the loads on these bearings and their L10 life specification, it is easy to make the conclusion that they should achieve very high levels of reliability but this is often not the case. If you go to one plant, site people often have trouble remembering the last slow speed bearing failure and then you can go to another site with similar equipment, product and environmental conditions and slow speed bearing failures are a painful ongoing regular occurrence. This presentation will give the reasons for tise difference in reliability performance and discuss the options for condition monitoring and elimination of the dominant failure modes.
