BIG-T® Chains

TSD BIG-T® Ketten

The flatter design of this chain – which is even flatter than the super-flat chain – makes it suitable for use on extremely compact conveyors (for low-seam applications*), or produces an extremely strong and durable chain for a given pan profile.
The round links have a flattened profile where they engage with the bottom of the chain pockets. This greatly improves the wear behaviour of the chain on the sprocket.
The leg diameter d1 is much smaller than the nominal diameter d – without any loss in chain performance. The benefits include a 15% saving in weight at the round link and a larger volume of material at the critical flight-bar profile, which significantly increases the stiffness and breaking force of the flight bar.
Additional advantages of BIG-T® Chains:

  • Very low built-in height
  • Overall wear behaviour of the chain is very much improved
  • Saving in weight without any loss in chain performance
  • Increases the stiffness and breaking force of the flight bar
