The rollers have a common vertex which enables true rolling motion within the thrust plates. The tapered roller thrust bearing design also allows for more rollers and therefore higher load-carrying capability. A full complement version is offered for many of the standard sizes by eliminating the cage. In this full complement bearing, the addition of more rollers gives agreater thrust capacity.

Sawdustis mixed with coal in thefuel yard and the mixtureis fed via roller mills to the burners. In the tests carried out in 1999 and 2000, when the share of sawdust varied between 1 and 8% on energy, it was noticed that milling performance was decreased and that the roller mills mainly dried the larger sawdust particles rather than pulverising them.

The working surface of the Coal Vertical Roller Mill bearing is subjected to alternating stress and causes failure. It mainly occurs on the working surface of the bearing, often accompanied by fatigue cracks, which are first generated from the maximum alternating shear stress below the contact surface and then extended to the surface to form different peeling shapes.
