The Sealing System

Amongst the most critical aspects affecting the life of a conveyor idler, are the design, manufacture and assembly of the sealing system. If the design is such that the seal effectively prevents the ingress of contaminants into the bearing, but increases frictional resistance of the roll, then increased wear on the tube will result in premature shell failure. On the other hand, utilising a seal, which limits frictional resistance to a minimum, but does not adequately protect the bearing, will result in contamination, and eventually premature bearing failure.

After many years of development and refinement, the Melco idler offers the most suitable combination of both, effectively protecting the bearing to limit contamination, without unduly increasing the rolling resistance, thus ensuring that the designed life is achieved. Melco’s extensive range of greased and sealed for life non-rubbing seals, are suitable for any application.
