TRACTION BELTING

The heart of all belted chain conveyor systems lies in the traction belting and DURABELT has the strongest belting available.


Here's why...
  • Its in the strength

    • Our rubber traction belting is reinforced with plies of polyester and polyamide fabric for outstanding strength.

  • Its long lasting

    • The reinforcing fabric in the rubber traction belting is resistant to breakdown caued by exposure to the environment.

  • Its flexible

    • The traction belting runs smoothly... even around rollers as small as 64 mm (2.50 in) diameter for low profile rubber belts, 76 mm (3.00 in)diameter for high profile rubber belts.

  • Its proven

    • The belting has more than 25 years of proven field experience behind it in both Europe and North America.

    Choosing between a low profile and high profile belt depends on the application and drive system desired.

    Traction Belt Profiles
    Figure 1: Traction Belt Profiles

    DURABELT's low profile rubber belt strength exceeds the requirements of the vast majority of belted chain applications and is a popular choice. It can be used with low profile belt drive sprockets where the sprockets teeth engage the steel rods of the belted chain assembly or with friction drive rollers.

    Various Drive Systems
    Figure 2: Various Drive Systems

    DURABELT's high profile belt is stronger than the low profile belt and is well suited to very heavy or high shock load conditions. It is also ideal in applications where slides are used under the traction belts to support the belted chain assembly since the high profile lugs give extra wear life.


    High profile belting can be used in any application that low profile belting is used. It is usually driven with high profile belt drive sprockets where the fingers on the sprockets engage the high profile lugs on the underside of the traction belts. It can also be driven with friction drive rollers or with certain types of low profile belt drive sprockets.


    The advantages of each type of drive system is explained in greater detail in the Drive Sprocket section of this catalogue.
