ROLLER SCREW ACTUATORS: PERFORMANCE & SERVICE

Roller screw actuators have several advantages over hydraulic or pneumatic actuators for many applications, especially those involving heavy loads and fast cycles. Other benefits include a small system footprint, long functional life, and low maintenance requirements. And because roller screw systems don’t require high-pressure fluid, they reduce noise levels and are not subject to potentially hazardous fluid leaks.

Universal Design for Ultimate Flexibility

The K Series actuators from Exlar provide a truly universal solution for a multitude of rod-style actuator applications. Now available in three frame sizes:

  • 60mm
  • 75mm
  • 90 mm

Big Performance and Small Form Factor

These robust electric actuators provide an ideal replacement for pneumatic cylinders and feature comparable dimensions with a similar form factor. The optional roller screw drives are a superior replacement for hydraulic cylinders. Better performance, greater flexibility, and longer life culminate to make the K Series a smart choice for many applications.

Multiple Models to Exactly Fit Your Needs

KX Series actuators are offered in three frame sizes, so you can choose the option that best suits your application requirements:

KX actuators

The high performance planetary roller screw in the KX class offers performance that is far superior to competing actuator technologies. These actuators are ideal for Exlar automation, mobile equipment, process control and many other demanding applications.

KM actuators Legacy product

The standard capacity and lower cost planetary roller screw in the KM class is most appropriate for applications where cost is a higher priority than long life. Nevertheless, these actuators provide twice the life of similarly sized ball screw actuators, along with high efficiency and greater shock resistance.

Other Advantages

  • Flexible design suitable for numerous applications and configurations
  • Universal mounting options compatible with DC, stepper, and servo motors
  • Preconfigured parallel and inline motor mounts available for most motors
  • Multiple models for maximum flexibility
  • Anodized aluminum housing with sealed body options for harsh environments
  • Specialized material and coating options
  • Built for long life and low maintenance

ACTUATORS: KX & KM

KX ACTUATORS: APPLICATIONS

The high-performance planetary roller screw in the KX class offers performance that is far superior to competing actuator technologies. As a result, these actuators are ideal for a range of demanding applications, including:

  • Exlar automation
  • Mobile equipment
  • Process control
KM ACTUATORS: LEGACY PRODUCT

The standard capacity and lower cost planetary roller screw in the KM class is most appropriate for applications where cost is a higher priority than long life. Nevertheless, these actuators provide twice the life of similarly sized ball screw actuators, along with high efficiency and greater shock resistance.

ROLLER SCREW TECHNOLOGY

Roller screws convert rotary torque into linear motion, similar to acme screws or ball screws. But roller screws can turn considerably faster and cycle more frequently than both acme and ball screws, making them an ideal fit for demanding continuous-duty applications.    

 

The roller screw design allows a larger radius with additional contact points to fit into the existing space, lowering the stresses within the system and lengthening its functional life. Because the number of contact points is greater, roller screws have high load-carrying capacity and improved stiffness.

 

HOW DO YOU OPTIMISE PERFORMANCE AND LIFESPAN?               

Roller screws, like other lead screws, should be well lubricated and must tolerate contaminants including abrasives, metal chips and non-lubricating fluids. Their life can be increased by regular grease and oil replenishment.

CHOOSING AN ACTUATOR

WHAT TO CONSIDER WHEN PREPARING THE COMPONENT SPECIFICATION?

Roller screw variables include the diameter, lead and sealing. When preparing the component specification, be sure to take into consideration the budget, maximum linear speed, maximum load, maximum stroke, necessary precision level, tolerance to the backlash, the contaminants present and the needed level of protection.

 

HOW TO SELECT A SUITABLE MOTOR?

A motor is selected by calculating the required torque as a function of load on the system

and lead of the roller screw and comparing it to available motors and power transmission components. For applications that require a specific motor, roller screws with a lower or faster lead, belt or gear reductions can be configured into the system.

1 - Input torque should be limited such that Max Force is not exceeded. For a parallel belt ratio, the input torque ratings must be divided by the belt ratio for allowable motor torque. The output force ratings remain the same.
2 - Maximum allowable actuator–generated force that can be applied routinely. Exceeding this force may result in permanent damage to the actuator. For maximum allowable externally-applied axial forces, consult factory. For high force, short stroke applications, consult factory.
