Conveyor Idlers

 

SALIENT FEATURE

  • Conforms to IS:8598-1987.
  • Minimum roller gap to maximize belt life as it eliminates danger of pinching and damaging belt.
  • Forward tilt of side rollers ensures proper belt training.
  • ‘Drop in type’ design facilitates easy mounting and removal of rollers.

 

Frame

  • Jig welded steel frame ensures precise roller alignment and interchangeability.
  • Inverted angle base provides strength, and directs spillage away from rollers thus preventing accumulation of material under roller, ensuring free running of roller without any power loss.
  • Foot straps each with two open end slot facilitate initial alignment of felt.

 

ROLLER

  • Roller shell is made of special ERW tubes with close tolerance.
  • Bearing housings pressed out of CRCA steel sheet are welded to the roller shell with the help of Co, welding machine to achieve least distortion and maximum dispatch.
  • All rollers are made free before dispatch.
  • Close tolerance solid shaft protects bearings by minimizing deflection.
  • Rollers are fitted with seize resistant ball bearings. These bearings are specially designed for Belt Conveyor applications.
  • Double multi labyrinth seals ensures maximum protection against dirt, dust and moisture to the bearings.
  • Bearing, seals and grease chambers are filled with high-grade lithium based grease and rollers are filled with high-grade lithium based grease and rollers are sealed for life, thus saving high maintenance cost during life of roller.

​

ACCESSORIES
