About this product

Product information from the supplier.

The Double-Center-Roller New Type Aligning Idler is a precision-engineered conveyor component designed to maintain optimal belt tracking and prevent costly material spillage. Featuring a sophisticated rotating assembly welded to a lower cross member, this idler utilizes two strategically positioned center rollers to create a balanced support system, ensuring the conveyor belt remains perfectly centered during high-load operations.

By integrating enlarged bearing and shaft diameters with conical rollers cast in durable rubber, this advanced aligning idler generates a powerful reverse damping effect whenever the belt begins to drift. This self-correcting mechanism eliminates manual adjustments and minimizes belt wear, providing a seamless, smooth-running transport solution for the most demanding industrial environments.

Frequently Asked Questions

Q: How does the Double-Center-Roller Aligning Idler prevent belt drift?

It uses conical rollers cast with rubber that create a reverse damping effect. When the belt shifts, the conical shape forces the belt back toward the center of the conveyor.

Q: Which bearing brands are used in these conveyor idlers?

We provide a range of high-performance bearing brands including SKF, FAG, NSK, HRB, ZWZ, and LYC to ensure long-term reliability.

Q: Can the aligning idlers be customized for specific belt widths?

Yes, we support belt widths ranging from 400mm to 2400mm. You can provide your product drawings or specific size parameters for a custom build.

Q: What coating options are available for corrosive environments?

For high-corrosion environments, we recommend Hot-Dip Galvanizing. We also offer electrostatic powder spraying and industrial painting in various colors.

Q: In which industries are these conveyor rollers most commonly used?

They are widely used in coal mining, cement plants, steel mills, power plants, quarries, and recycling industries where heavy-duty material conveying is required.

Q: What is the expected lead time for an order?

Our standard delivery time is typically between 10 to 15 days, depending on the complexity and volume of the order.
