Friction Torque Limiters


PT Tech's SL Series is a friction torque limiter designed for standard torque and energy requirements for mining applications. This is an economical way to protect your expensive drivetrain from shockload damage, while allowing your equipment to contine to perform.

No resetting is required after shockloads occur and torques are pre-set by your design staff.  PT Tech has other model torque limiters for application requiring greater torque capacity within the same diameter as the SL series.

  • Single or Multi-Disc
  • Hollow motor shaft mounted
  • Compact design
  • Custom designed for your application
  • Low output inertia
