Flex-Lag® Rubber Lagging

  • Plain Rubber Lagging
  • Diamon Pattern Rubber Lagging
  • Light Duty Lagging

Flex-Lag® Rubber Lagging has been developed in multiple styles including Light-Duty, Plain-Pattern, and Diamond-Pattern to meet the needs of any application.

Because the lagging comes in rolls, virtually any pulley dimension can utilize Flex-Lag.

Features and Benefits


Light-Duty

  • Specially designed for pulleys with diameters as small as 50 mm.
  • Moisture is channeled between small raised buttons that support and grip the belt and deliver superior traction.
  • Available in SBA
  • Can be made in rolls up to 75m long, dependent on lagging thickness

Plain-Pattern

  • Helps prevent belt slippage in dry environments
  • Provides larger surface contact area relative to other patterned lagging
  • Horizontal grooves channel water and debris while providing a better dynamic interaction with the belt compared to sheet lagging
  • Available with FRAS approved rubber, marked in blue for easy identification on site

Diamond-Pattern Rubber

  • Diamond pattern features a bidirectional design for superior water-shedding characteristics
  • Horizontal grooves provide a second method to disperse water and debris off the lagging and prevent hydroplaning
  • Performs well in both dry and wet applications
  • Available with FAAS approved rubber, marked in blue for easy identification on site

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
