Servo linear actuators with roller, ball screw

The IMA55 and IMA22 servo linear actuator by Tolomatic integrate a servomotor and a ball or roller screw designed for several uses.

Tolomatic’s integrated servo linear actuator family includes the new IMA55 with roller screw and thrust capability up to 6,875 pounds force, and the compact IMA 22 with ball screw and up to 325 pounds force. Courtesy: TolomaticTolomatic’s IMA55 high-force servo linear actuator is now available with an optional roller screw that boosts its thrust capability to 6,875 pounds force (30,470 N). In addition, a new compact IMA22 integrated-motor actuator has been added to the line. The IMA22 features a ball screw and can deliver up to 325 pounds force (1,446 N). Available in four sizes, the IMA line of integrated-motor rod actuators features stroke lengths from three to 18 inches (76.2 to 457.2 mm) at speeds up to 24 inches per second (610 mm/sec). The addition of these two actuators significantly expands the range of applications for these actuators to include pressing, clamping, valve control, spot welding and volumetric filling.

All of the IMA actuators integrate a servomotor and a ball or roller screw for long service life that is designed to fit a multitude of budgets. With its integrated servomotor, the IMA actuator is shorter for a given stroke length than other types of rod actuators. Its patent-pending design allows for easy re-lubrication of the screw without disassembly, reducing maintenance and increasing service life compared to other rod actuators without this feature.

A variety of available modifications to the IMA line of integrated-motor actuators expand the range of operating environments. Modifications include:

  • Food-grade white epoxy coating with stainless steel hardware and mounting options for greater corrosion resistance in food and beverage washdown environments;
  • Ingress protection ratings of IP65 (standard), IP67 (optional) and IP69k (modified standard).

Both the IMA22 and IMA55 actuators feature a hollow-core rotor design that allows the nut of the screw to pass inside the rotor, creating a very compact package. This decreases overall actuator length compared to standard actuators due to the elimination of a separate motor, motor mount and gearbox. In addition, the motor features skewed stator windings to minimize cogging of the motor and provide more efficient motion with improved force repeatability.

Annual Salary Survey

Participate in the 2013 Salary Survey

In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.

Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
