Modular - Rotating Machine Screw

Modular actuators can be easily adapted to different applications by combining or modifying modules. They can be scaled up or down to meet specific force and speed requirements, making them suitable for a wide range of applications. Individual modules can be replaced or repaired without affecting the entire system, reducing downtime.

Features and Benefits

  • Integral Housing Flange for NEMA 56, C-face Mounting Flange
    Allows flexibility and easy customization, as different modules can be combined or replaced to suit specific application requirements.
    Three-Piece Flexible Coupling  
    Simplifies the connection between the actuator and the motor.
  • Highly Customizable
    Four (4) threaded holes in base for standard hydraulic cylinder, clevis end accessory attachment. Tapped 1/2 20 UNF-2B.
  • Rolled Thread Lifting Screw with Work Hardened Finish
    Reduces coefficient of friction between screw and lifting nut. Provides smooth, efficient operation and long service.
  • Steel Worm and Bronze Gear
    Worm gears tend to operate more quietly due to the sliding contact between the gears. Bronze possesses superior thermal conductivity, which helps to manage operating temperatures effectively, preventing overheating in high-speed applications.
  • Corrosion Resistant
    Rugged, lightweight aluminum housing is corrosion resistant.
  • Bronze Lifting Nut for Longer Life
    Good wear resistance: The differential hardness between the steel worm and bronze gear allows the bronze to deform slightly (run-in) to the worm's profile, improving contact and load distribution.
  • Standard Grease Fitting on Housing
    Easy lubrication of worm gear.
  • Stop-pin at End of Lifting Screw
    Prevents inadvertent run-off of lifting nut.

Notes:
1. Model M-2462 is self lowering and a motor brake should be used.
2. Model M-2463 may drift 0.75 in (20:1 ratio) to 2.0 in (5:1 ratio) when motor is shut off. If this is undesirable, a motor brake should be employed.
3. When ordering other than 56C-face actuators contact applications engineering at 800-477-5002.
