Steel Idler


Steel Idler

Manufacturing Quality:

The Moret Mining steel idlers is designed to have a minimal rim drag, break away mass, bearing misalignment and peripheral run out. This allows the idlers to have a low friction force that extends the life of the conveyor idler and this minimises noise levels.

The low rim drag and break away mass aid in the reduction of electrical consumption on start up and running of the conveyor system. The Moret Mining Seal allows for zero ingress of water and dust, this allows for the maximum protection of the bearing by eliminating contamination of the bearings. The seals are also available in a flame-retardant and self-extinguishing option.
Shaft end styles available: Closed end, open ends, Jeffry type, threaded and garland type.

Other steel Idlers:

Moret Mining manufactures underground extended shaft idlers and various type of garland sets.


The manufacturing quality of the idlers conform to the SANS 1313-1/3 specifications.
