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 2" (50 mm)
  • Moisture channeled between small raised buttons that support and grip the belt and deliver superior traction.
  • Available in SBR and White Nitrile

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 in SBR rubber and FRAS-approved rubber

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 in SBR rubber and FRAS-approved rubber
