The GUIDLER®, a Guide Idler and Conveyor Belt Tracking Guide, was developed during the 1940's to assure reliable Belt Conveyor Tracking in the following industries:

Coal, sugar, salt, mineral mining, cement, sand and gravel, smelting and refining, crushed stone, iron and steel, coal fired power plants, paper, brick, lime, gypsum, potash, fertilizer, roofing, baking, food manufacture, grain, abrasives, glass, asphalt, tire manufacture, chemicals, soda ash, tidal and river docks.

Subsequent minor refinements over the past 70 plus years by the Knapp family has resulted in the GUIDLER'S use world-wide. Improvements have only been incremental - proof that the original design was almost perfect in every respect.

Attempts to control tracking with a conventional cylindrical guide idler or typical conveyor belt tracking guide are usually unsatisfactory because the lateral forces acting on the belt exceed the belt's resistance to curling as it makes point contact with the guide. Severe belt damage is the result.

When properly inclined 30° in direction of belt travel our Guide Idler and Conveyor Belt Tracking Guide provides:

  • Up to 4" of straight line contact to absorb lateral belt loads and eliminate edge curl.
  • Belt entrapment to prevent climb-over as is common when using cylindrical guides.
  • Axial movement of up to 5/8" to accommodate belt heave and oscillation.
  • Quality American manufacture assuring long life and zero maintenance.
Awarded highest honors as the world's best guide idler and conveyor belt tracking guide at The Inventor's International Exposition in Brussels, Belgium.
