A typical idler can be seen below together with an indication of the individual components :
The improved sealing arrangement protects the bearing from dust and moisture, as well as other environmental contaminants. In addition, the quality of idlers also varies depending on the quality of the individual components and of the manufacturing process.
Conveyor idler Roller Structure
Idler roller consist of idler roller shell, Shaft, bearing, bearing house, seals and axial clip etc.
1. Tube or shell. The Shells are made from steel tube with close tolerance ensuring smooth, Shock free and eccentricity free running with minimum dimensional run out, smallest rotating weight of rollers requires low horse power, thereby conserving power and energy due to lowest possible dynamic friction.
2. Seals should be multi labyrinth type to prevent ingress of dirt, air and moisture. The outer seal should be corrosion resistant.
3. Bearing housing are formed from strip steel deep pressed in automatic presses machine, this tolerance allowing a perfect match between the bearing and the relevant parts of the sealing.
4.Bearing. Large clearance C3/C4 serials deep groove ball bearings, reinforced cage with big rivet, thick inner ring and outer ring. usually use double sealed structure to improve the water and dust proof ability.
5. SHAFT: Shaft is formed from cold drawn round bar and calibrated to ISO to ensure precise assembling of bearing.
