Modular - Rotating Ball 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 for flexibility and 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 threaded holes in base for standard hydraulic cylinder, clevis end accessory attachment. Tapped 1/2 20 UNF-2B.
  • Ball-bearing type screw and mating nut with rolling contact
    Reduces friction to a minimum providing capability for higher speed and longer life with less power requirement
  • 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.
  • Standard Grease Fitting on Housing
    Easy lubrication of worm gear.
  • Stop-Disc at End of Lifting Screw
    Prevents inadvertent run-off of ball nut.

Notes:
1. Model M-2462 and M-2463 are self lowering and a motor brake must be used.
2. Due to hight travel speed of BM-2462, it is important that a brake with a minimum response time be used. An independently controlled direct acting brake (6ft-lb for 3/4 HP Motors and 3ft-lb for smaller motors is recommended.
3. When ordering other than 56C-face actuators contact applications engineering at 800-477-5002.
