The Flex-Lag® Plain-Pattern Lagging is built for conveyor systems operating in low-slip, dry, or indoor environments where consistent traction and pulley protection are essential. Its smooth rubber surface provides stable belt contact without excessive grip, helping to reduce noise, vibration, and pulley wear.
Engineered with high-quality SBR rubber, this lagging offers excellent resistance to abrasion and tension stress while maintaining flexibility for easy installation. Suitable for both drive and non-drive pulleys, the Plain-Pattern Lagging provides an economical and long-lasting solution for maintaining belt performance and extending pulley service life.
Light-Duty Lagging
- Compact and Efficient: Specially engineered for small pulleys with diameters as small as 50 mm, making it ideal for light-duty and compact conveyor systems.
- Superior Moisture Control: Small raised rubber buttons grip and support the belt while channeling away moisture to maintain consistent traction.
- Durable SBR Rubber: Constructed from high-quality SBR (Styrene-Butadiene Rubber) for long-lasting flexibility and wear resistance.
- Extended Length Options: Available in rolls up to 75 m long, depending on lagging thickness, for greater coverage and fewer joins during installation.
- Reliable Performance: Delivers excellent traction and belt protection for light, intermittent-duty conveyors across various industries.
Plain-Pattern Lagging
- Slip-Resistant Design: Helps prevent belt slippage in clean, dry operating environments while maintaining a steady, quiet belt motion.
- Greater Belt Contact: Provides a larger surface area than patterned lagging, ensuring smoother, more stable belt interaction.
- Grooved Functionality: Horizontal grooves channel away water and debris, improving traction and dynamic belt performance compared to traditional sheet lagging.
- Certified Safety: Available with FRAS-approved rubber, marked in blue for easy on-site identification and compliance in regulated environments.
- Easy to Install: Features drainage grooves spaced at 3.14″ (π) intervals for effortless trimming and alignment during installation.
Diamond-Pattern Rubber Lagging
- Bidirectional Design: The unique diamond pattern provides superior water-shedding capability in both directions, keeping pulleys clean and dry.
- Enhanced Debris Removal: Horizontal grooves work alongside the diamond pattern to remove water and debris efficiently, reducing slippage and hydroplaning.
- Reliable in All Conditions: Performs exceptionally well in both wet and dry applications, maintaining consistent traction under variable conditions.
- FRAS Certified: Available with FRAS-approved rubber, clearly marked in blue for easy compliance and identification.
- Simplified Installation: Includes drainage grooves spaced at 3.14″ (π) intervals to make trimming, fitting, and on-site installation faster and cleaner.

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.
Installation
Installing Flex-Lag® Lagging is fast, simple, and can be completed without removing the pulley from the conveyor system.
- Determine Requirements: Refer to the Strip Selection Guide in the sell sheet to calculate the correct number of rolls or strips for your pulley size.
- Prepare the Surface: Clean and roughen the pulley face to ensure optimal adhesive bonding.
- Apply Adhesive: Use Flex-Lag® Cold Vulcanizing Adhesive to secure the lagging firmly in place.
- Mount the Lagging: Align the strips or rolls carefully, pressing evenly to eliminate air pockets and ensure a smooth fit.
- Cure & Inspect: Allow the adhesive to cure fully before restarting the conveyor to ensure long-lasting performance.
This labor-saving cold vulcanization process provides a durable, reliable bond for on-site installations — minimizing downtime while ensuring lasting pulley protection and improved belt traction.
Common Industries That Use This Product

Manufacturing & Assembly Lines
Food & Beverage Packaging


Warehousing & Logistics
Distribution centers and parcel sorting facilities use this lagging for drive pulleys in clean, dry conditions. The balanced friction level maintains reliable belt tension without slippage or excessive wear. Its smooth, uniform surface runs quietly and requires minimal maintenance. Over time, it helps reduce energy consumption and extend the lifespan of both belts and pulleys.
