Bolt | Reciprocating Electro-Mechanical Actuator

Bolt Reciprocating Actuator

The Promess Bolt is a reciprocating actuator paired with Promess’ UltraPRO controller to form a complete package intended for applications requiring programmable, rapid, non-stop motion at frequencies not well suited for a ball screw-type press.

Bolt can operate at any speed up to 10 cycles/second with a dynamically adjustable amplitude and a driving force up to 60 kN. Built in force and position sensing provide feedback to make decisions on the fly and to collect detailed test data.
