Conveyor pulley bearing configurations can vary considerably and as such lubrication programs must be designed to take the specific requirements of different bearing and seal combinations into account. Overall, for typical spherical roller bearings with labyrinth or taconite seals, the lubrication strategy must address two requirements:


1) The re-lubrication of the bearing rolling elements to prevent lubricant starvation and;


2) The regular purging of seals to prevent the entry of contaminants.
