Return Idler

 Supporting Efficiency on the Conveyor's Return Journey

Return idlers are critical conveyor components specifically designed to support the empty conveyor belt on its return journey from the discharge point back to the loading zone. Positioned along the underside of the conveyor frame, these idlers maintain proper belt alignment, prevent excessive sagging, reduce friction, and protect the belt's underside from damage. Their proper selection and spacing are fundamental to minimizing energy consumption, extending belt life, and ensuring reliable conveyor operation across all industrial applications.

Conveyor idlers: Available in diameters ranging from 50 mm to 219 mm (2 1/2" to 8 5/8"), with lengths from 190 mm to 3400 mm, to suit a wide range of conveyor systems.

Idler tube: Made from Q235 (equivalent to SS400/JIS G3101/EN10025/ASTM A36 ) steel for durability and strength.

Idler shaft: Constructed from 45# (equivalent to DIN:C45/EN:C45/JIS:S45C/ASTM A1045 )steel for reliable performance.

Bearing: Equipped with single and double row deep groove ball bearings, with 2RZ and 2Z options available, and C3 clearance for enhanced efficiency and reduced friction.

Seals system: Features a grease retaining inner seal with multi-stage labyrinth design, along with a retention cap, to prevent dust and debris from entering the bearing.

Lubrication: Uses lithium soap type grease with rust inhibitors, to ensure smooth and reliable operation.

Welding technology: Utilizes mixed gas shielded arc welding for strong and consistent welds.

Painting technology: Offers a variety of painting options, including ordinary painting, hot galvanized painting, electric static spraying painting, and baked painting, to suit the specific needs of each application.
