MECHANICAL FEATURES – Group 22 Rotary Actuators

Housing: Superior Protection
with Convenient Access to Components

Beck’s durable gear train maintains accurate, consistent control element positioning even under the demanding conditions of an active control loop.

  • Gear trains employ a unique, all spur gear construction of heat-treated alloy steels and ductile iron.
  • Efficient, wide-face spur gearing virtually eliminates wear-induced backlash and positioning inaccuracies.
  • Durable design provides up to 4 days of protection against intermittent or extended accidental stalls.
  • Integral self-locking mechanism ensures that drives hold a load with the motor de-energized.

Drive Train:
Durable and Efficient


An easy-to-turn, spoke-free Handwheel is incorporated into the Group 22 design to allow manual operation during installation or power outages.

  • Move dampers to any position smoothly and easily without power, even under full load conditions.
  • Mechanical stops in housing prevent manual overtravel.

Manual Handwheel: Convenient Manual Control Without Declutch


CPS-4 Compartment

Beck drives feature a cast aluminum body with individual compartments to protect components from moisture and dirt, and allow easy access for installation and calibration.

  • Precision-machined aluminum alloy castings with corrosion resistant poly-urethane paint provide a rugged, dust-tight, weatherproof enclosure.
  • Individual compartments protect all major components: Motor, Digital Control Module, Contactless Position Sensor, gear train, and installation wiring terminal board.
  • Each compartment can be accessed without exposing other components.
