Flex-Lag® Diamond Pattern Rubber Lagging

The Flex-Lag® Diamond Pattern Rubber Lagging is engineered to enhance conveyor performance by improving friction between the belt and pulley. Its diamond-shaped grooved surface channels away water, dirt, and debris, ensuring consistent belt contact and reducing slippage in both wet and dry conditions.

Built with a durable rubber compound, this lagging protects pulley surfaces from wear and extends belt life by minimizing tension loss and misalignment. Ideal for both drive and non-drive pulleys, the Diamond Pattern Lagging offers a reliable, cost-effective solution for general-purpose material handling operations.

Enhanced Grip: Features 15% ceramic tile coverage, combining the strength of ceramic with the flexibility of rubber for improved belt traction.
Superior Friction: The large ceramic tiles are molded directly into the diamond-shaped rubber surface, significantly increasing the coefficient of friction compared to standard Diamond Pattern Rubber Lagging.
Efficient Water Shedding: The bidirectional groove design channels away water and debris from both directions, ensuring stable performance in wet or variable conditions.
Cost-Effective Performance: Offers many of the advantages of a full ceramic product — including added grip and wear resistance — at a more affordable price, making it ideal for light to medium-duty applications.
Certified Safety: Available with FRAS-approved rubber, marked in blue for easy on-site identification and compliance with fire-resistant and anti-static standards.

To select the right pulley lagging, be sure to consider the environmental conditions around the pulley:

Belt condition, i.e., wet or dry
The service required for bonded lagging versus weld-on
The expected wear life of the lagging

*Additional thicknesses and widths available as special orders.

Installations

Installing Flex-Lag® Diamond Ceramic Lagging is fast, efficient, and does not require removing the pulley from the conveyor system.

Determine Lagging Quantity: Use the Flexco Lagging Calculator to determine the exact number of rolls or strips needed for your pulley size.
Surface Preparation: Clean and roughen the pulley surface to ensure strong adhesion.
Apply Adhesive: Use Flex-Lag® Cold Vulcanizing Adhesive to bond the lagging directly to the pulley.
Mount Lagging: Align the strips evenly and press firmly for full surface contact, removing any trapped air.
Curing: Allow sufficient curing time before resuming conveyor operation.

This cold-bonding process saves labor, reduces downtime, and allows on-site installation — providing a durable, high-traction solution that’s ready to perform immediately.

Common Industries That Use This Product

Power Generation

Coal and biomass handling systems benefit from this lagging’s consistent traction and wear resistance. It prevents slippage that can lead to uneven belt tracking or heat buildup, ensuring reliable, efficient conveyor operation in power plants.

Cement & Concrete Production

Cement plants use diamond-pattern lagging to prevent belt slippage caused by dust and heavy loads. Its abrasion-resistant rubber withstands the harsh conditions of clinker, limestone, and aggregate transport. Over time, it helps extend pulley life and reduce downtime from maintenance.

Fertilizer & Chemical Processing

In fertilizer and chemical plants, conveyors often operate in moist, corrosive, or abrasive conditions that quickly wear down standard pulley lagging. The Flex-Lag® Diamond Ceramic Lagging provides superior grip and chemical resistance, helping to prevent belt slippage and material buildup. Its bidirectional grooves shed moisture efficiently, keeping the pulley surface clean and reliable. This combination of traction and durability ensures steady material flow and longer equipment life, even in highly corrosive environments.
