Snap Top Chain TNU  Major Specifications

TNU

Features, Construction, Types

Features
  • Curved conveyance chain with high allowable load (double the allowable load of TTUP chain). The sideflexing version of TN Snap Top Chain.
  • Replacing top plates is simple and easy.
  • Base chain types available for operating environments where corrosion could be a problem.
Construction
  • TNU top chains consist of snap top plates and ANSI #60 base chain. The “legs” of the top plates are used to snap the plates onto the outer links of the base chain and to hold down the detachable plates and prevent them from coming loose.
Types
  • Base chain is steel, and main dimensions are the same as standard roller chain. Note, however, that the shape of the pin ends is different. Base chain requires lubrication.
  • NP Type
      Base chain is nickel-plated standard chain. The nickel plating makes for a better appearance, as well as providing corrosion resistance. Lubrication is required.
  • Pins, bushes, and rollers are made of precipitation-hardened stainless steel. Plates are made of 304 stainless steel. Suitable for corrosive environments. Lubrication is required.
