Exlar I Series actuators present a new range of alternatives for linear motion solutions. The I Series actuators offer all of the benefits of Exlar's planetary roller screw technology, along with extreme flexibility in actuator mounting style, and the type of motor used to drive the actuator.

Exlar's roller screw technology has been the integral component in creating the most reliable, long lasting electromechanical actuators on the market. For the last 15 years, Exlar's inverted roller screw actuators have provided a long-life, all-electric replacement for hydraulic cylinders in thousands of applications.

I Series Features

  • Proven Exlar roller screw technology
  • Flexible mounting options
  • Adapts to various types of motors
  • Optional inline planetary gear reducer for high force output from lower motor torques

Two Models to Fit Your Needs

Two product performance levels are available, so you can choose which option best suits your application and budgetary requirements. The IM Series offers Exar's standard capacity inverted roller screw in actuators with up to 5 times the travel life of ball screw actuators.

The IX Series offers the same load-carrying capacity as the IM but offers up to 15 times the life of an equivalent ball screw.

IX Series Features

  • IP65 sealing
  • Roller screw capacity 15X greater than ball screw
  • Low backlash

IM Series Features

  • IP54 sealing
  • Roller screw capacity 5X greater than ball screw
  • Standard backlash

Motor Flexibility

The I Series actuators can be ordered to accept the motor type of your choice. Whether a brushed type DC motor or stepper motor for lower performance applications, or a high performance brushless motor like Exlar's SLM Series, the I Series actuators offer complete flexibility in ordering to accept any type of motor.

Integral Planetary Gearing

The I Series actuators offer economical planetary gearing as an input reduction option. Compared to the low performance spur gears provided by most ball screw actuators, the I Series' planetary gears offer an extended life, high input speed and output torque and quite operation. The performance of the actuator is not limited by the gearing. Standard available ratios of 5:1 and 10:1 allow you to utilize smaller, lower torque motors to drive the I Series actuators, while still achieving the desired output force from the actuator.

Sealed Actuator Body

The base unit of the IX Series actuators is offered with a standard IP65 rating. The in-line motor mounting adapters and parallel motor mounting adapters can be ordered as IP65 if required for the application.

The base unit of the IM Series actuators is offered with a standard IP54 rating. An optional IP65 sealed base unit is available. The in-line motor mounting adapters and parallel motors mojunting adapters can be ordered as IP65 if required for the application.

Wear and Corrosion Resistant Output Rod

The standard actuator's main extending rods for the I Series actuators are provided with a surface treatment that provides equivalent corrosion resistance and superior wear resistance to chrome plated rods. The thermo-chemical process creates a surface that is a microstructural zone of iron nitrides, integral with the base material. The resullting surface not only has superior wear qualities compared to chrome, and equivalent corrosion resistance, but also eliminates the flaking issues of an electro-chemically applied process such as chrome plating.

Large Diameter Output Rod

The I Series actuators provide a large diameter output rod and excellent internal bushing support which offers you long life in resistance to side loading.

Actuator Materials and Coating

The standard IM and IX Series actuators provide case materials made of aluminum with clear and black anodized coatings. These materials offer a durable and corrosion resistant package. The standard mounting hardware for the actuators is manufactured from black oxide coated mild steel.

Alternative Materials and Coatings

The I Series actuators offer several options to the standard construction for applications requiring further corrosion resistance. The actuator's case parts can be ordered as electroless nickel coated white powder coat epoxy. Alternatively, the entire case can be constructed from stainless steel using materials selected by the customer.

The mounting hardware for the I Series actuators can be ordered in two varieties offering more corrosion resistance than the standard components. These include the "corrosion resistant" mounting accessories which are constructed of mild steel and provided with the same surface preparation as the output rod. Also offered are mounting accessories manufactured from stainless steel.
