Anti-Roll Back Idlers



HDPE Anti-Roll Back Idler





Steel Anti-Roll Back Idler








Manufacturing Quality:

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

Ultra brake Anti Roll back:

This one directional invention is a standard idler that is equipped with a brake system that prevents the idler from rolling back.
Normaly installed on long and steep inclines.

Functions:

• The inner race turns in the forward direction, for normal operation without adding friction.
• Should anything happen, that the roller wants to turn back, the inner race wedges itself against the shaft
       and the narrow part of the outer race profile, will stop the idler.

Flame-retardant and self-extinguishing:

Moret Mining manufactures a flame-retardant and self-extinguishing HDPE idler of which the HDPE tube and seals are flame-retardant and self-extinguishing.

Key features of the Moret HDPE Idler:

• The HDPE Idlers are significantly lighter then steel idlers.
• The HDPE idlers are more corrosion resistant than steel idlers.
• The HDPE Idlers produces less noise than the steel idler.
• The HDPE idlers has more wear resistance which extends the idler lifespan.

Shaft end styles available:

Closed end, open ends, Jeffry type, threaded and garland type.

Other HDPE 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.
