M-series ball screw


The ball screw actuator can run at higher duties and speeds than machine screw actuators through the high efficiency of the ball screw and nut. The ball screw also provides longer life at load and requires less power than a machine screw actuator for a specified thrust. The range is available with the same number of metric and imperial variants as the machine screw range. All metric models have a ball nut safety device as standard. A high duty cycle model for continuous operation is also available.
  • Move Loads and apply force more efficiently than machine screw actuators
  • Permit faster operation and longer life under load
  • Require less power by providing positive mechanical action
  • Permit synchronisation of multiple units
  • Capacity from 1/2 to 50 tons (4.5 kN to 450 kN)
  • Handles full load in tension or compression
  • 40 models available

Standard Features

  • High Speed - Low friction permits linear motion in some models up to 300 inches/min (7.62 m/min) at 1800 rpm worm shaft speeds, providing maximum horsepower ratings are not exceeded.
  • Precise Positioning - Can be controlled accurately for positioning within thousandths of an inch.
  • Positive Action - Operates with a high degree of reliability, without the need for costly pumps, hoses or valves
  • Long-Life - Low friction means longer operating life.
  • Low Power Usage - Highly efficient design means less power is needed to achieve a given thrust; power needs are much as two-thirds that of machine screw actuators.

Options

  • 3 Standard Gear Ratios - Wide selection of gear ratios, increases the amount of raise rates available.
  • 2 Ball Screw Lead Options - On the 2, 5 and 10 ton models there is the option of either the standard or a 1“(25.4 mm) lead for rapid raise rates.
  • Screw on Ends - The standard actuator has a threaded end to which clevis or top plates can be screwed. Note these items are shipped loose and must be spot drilled before seating set screws in field installations.
  • Bellows Boot Option - Protects the screw from dust, dirt, moisture and corrosive contaminants.
  • Double Clevis End Option - Incorporates a special clevis end bottompipe and standard clevis end on the lifting screw.
