General Use Drive Chains

Previous 1 / 1 Next


Tsubaki RS Roller Chains, the world's most trusted brand in power transmission chains.

Tsubaki RS Roller Chain complies with world standards, such as JIS, ASME and ISO. Typically, roller chains are used as economical means of transmitting mechanical power of large loads at low speeds.
 
However, it is also possible to use this chain in high-speed applications with proper maintenance and lubrication.

Features of roller chain transmission


  • Large reduction ratio (usually up to 1:7)
  • Chains can be used with long shaft center distances (normally up to 4m). By changing the number of links it is possible to freely adjust the shaft center distance.
  • The chain can be used on both sides and drive multiple shafts at the same time.
  • Easy installation and replacement (easy to cut and connect chains).
  • If the distance between shafts is short, it can be used vertically.
  • The sprocket diameter of a chain drive could be smaller than a belt pulley while transmitting the same torque.
  • Transmitting power by meshing many teeth results in less wear of sprocket teeth than gears.
  • Chain drives have greater shock absorption than gear drives.

Structure



Super Long Length Formation for Large Size Roller Chain


As the chain size increases, so does the amount of difficulty of connecting the chain. By delivering connected chain of the desired length, we can increase our user's work productivity.

Product Lineup


RS Roller Chain


ISO ANSI standard roller chain. The new G8 Series (RS40-240) features 1.2 times longer wear life than the previous G7 Series thanks to the development of a rust preventative pre-lube that minimizes tackiness.


 

BS/DIN standard RS Roller Chain

BS/DIN standard chain is used for European mechanical equipment. The latest model GT4 winner is manufactured with the proprietary technologies of the G7-EX series and has doubled the wear life.
