Stairs or walkways may be incorporated to access transfer points located above surge storage bins or processing plants  Time required for manual greasing cycle leaves less time for effective relubrication frequency / volumes  Restricted access due to hazardous conditions (under transfer / conveyor feed points, elevated take-up pulleys or take-up trolleys) Maintenance challenges which restrict or limit effective relubrication may result in:  Inadequate grease purging of seals, allowing water or abrasive particle contaminants to enter the bearing housing  Contamination of bearings (from inadequate lubrication) causing rapid deterioration of lubrication conditions  Accelerated wear rates (caused by contaminants) and finally premature bearing failure Industry: Quarry Application: Conveyor bearings Lubrication system: perma FLEX Installation solution: Direct mount incl. manual purge valve Industry: Iron ore mining Application: Conveyor bearing / seal (hybrid solution) Lubrication system: perma STAR VARIO Installation solution: Remote cage hanger mount
