Heavy duty bearing design ensures maximum load and speed capacities so not only are you maximizing safety, but you’re not sacrificing productivity for it.
Automatic Locking
Beyond +/-10° rotation from the vertical axis KL Safety Chucks begin to automatically lock, achieving full lock at 30° to ensure maximum safety from accidental shaft rotation.
Rugged, Hardened Design
Montalvo KL Safety Chucks are designed to withstand the harshest environments and working conditions while never sacrificing safety or performance.
Replaceable Handwheels & Journal Seats
As the only Wear Part on the KL Safety Chucks, handwheels and journal seats are easily replaceable with only a wrench required.
Pedestal Mount or Flange Mount Options
Square, Triangle and Diamond Journal Seats Available
High Speed
KL Safety Chucks are capable of winding speeds of more than 300 m/min with the use of the high speed option.
Superior Concentricity
Tightly held journal seat tolerances provide superior roll winding/unwinding concentricity.
Extreme Torque Performance
Whether its 398 in-lbs or all the way up to 17,702 in-lbs, KL Safety Chucks give you the torque performance you need.
