Flex-Lag® Weld-On™ Rubber Lagging

Flex-Lag® Weld-On™ Rubber Lagging

Flex-Lag® Weld-On™ Rubber Lagging features a patented gear-tooth design. This eliminates the wide gutters present in conventional weld-on lagging products and also helps minimize problems associated with vibration, cleaner chatter, and overall belt cleaner compatibility. 

Features and Benefits

  • Diamond pattern is based on rain tire tread designs for superior water-shedding characteristics
  • Performs well in both dry and wet applications
  • Lagging strips are designed to CEMA pulley width standards to eliminate waste and reduce installation time by up to 50% over similar weld-on lagging products
  • Available in SBR rubber and FRAS-approved rubber
 

Specifications

  • Minimum Pulley Diameter: 16" (400 mm) 
  • Thickness: 5/8" (15 mm)
  • Temperature Rating: 5° F to 185° F (-15° C to 85° C)
  • Rubber Compound: SBR (Styrene-Butadiene-Rubber)
  • Rubber Hardness: 68 ± 3 Shore A
  • FRAS (Fire Resistant Anti Static) - MHSA Certification # MSHA NO. IC-190
  • Ceramic Compound: Aluminum Oxide (Al203)
  • Ceramic Hardness: 83 HRA Rockwell Hardness Scale A
  • Strip widths from 20" to 101" (500 mm - 2560 mm) to match pulley face widths
  • Also works with pulley diameters ranging from 16" to 72" (400 - 1800 mm) to match belt widths

Installation

  • Use the Flexco Lagging calculator to determine the appropriate number of strips required for your application
  • Flex-Lag does not require removing the pulley from the conveyor system

How to Select the Right Lagging Product

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
