Bandsaw blade automatic tensioner


Astech has designed an automatic tensioning system for the bandsaw blades, adaptable to the SRA automatic bandsaw machines.

By turning a selector, a pneumatic mechanism acts by automatically tensioning and relieving the bandsaw blade on the pulleys.



  • Automatic tensioning and releasing (turning a selector)
  • Safer blade change operation
  • Reduction of the change time
  • Adjustable blade tensioning pressure
  • Constant tension in time
  • All the bandsaw blades are tensioned in the same way.
  • Adaptable to Astech SRA machines
