2. Performance Advantages
• The roller is specially processed to prevent damage to the conveyor belt.
• Radial runout ≤0.35 mm
• Low rotating resistance reduces conveyor drive power consumption
• Excellent waterproof and dustproof performance
• Waterproof test lasts 72 hours with zero ingress
• Long service life, roller life is generally not less than 30,000 hours
• Stable performances in the harsh environment of mines and industries
3. Applications
Idler rollers for conveyor belts are used in many industries. Here are some examples of conveyor idler roller applications:
• Coal mine conveyor belts
• Underground mining conveyors and surface miners
• Quarry conveyor systems and aggregate plants
• Cement conveyor belts used in cement plants
• Steel plant conveyor systems
• Power plant conveyors
• Bulk material handling systems used in ports
• Sand and gravel conveying systems
• Chemical plant and fertilizer plant conveyors
• Long distance conveyor systems
4. Custom Options
We can manufacture conveyor idler rollers to your specifications or requirements based on your conveyor system. You can customize many different features when ordering conveyor rollers. Some customizations available include:
• Roller Diameter
• Roller Length
• Shell Thickness

5. FAQ
5.1 What do conveyor idler rollers do?
Conveyor idler rollers support the conveyor belt and allow the materials to smoothly travel along the length of the belt conveyor.
5.2 What sizes of conveyor rollers are available?
Available sizes for conveyor idler rollers range from 63.5mm to 219mm in diameter. These are the commonly available sizes but we can supply custom diameters.
5.3 How long are conveyor rollers?
We normally stock conveyor rollers from 150mm to 3500mm in length. Longer sizes can be manufactured to suit conveyor application.
5.4 Are conveyor rollers waterproof and dust proof?
Yes. The conveyor rollers use a labyrinth sealing structure which provides excellent waterproof and dust proof capabilities.
5.5 Can I get custom conveyor rollers made?
Yes. Customers can supply their own diameters, lengths, shell thickness, bearing models and even shaft sizes. The sealing structure can also be changed to customer’s requirements.
