From piercing, punching or riveting applications in the automotive industry to press applications within industrial automation, a linear actuator can be found in virtually all manufacturing sites, sharing the common goal of moving a load. Until recently hydraulics and pneumatics have been the primary options for linear actuation. Increased accuracy and energy efficiency are accelerating the trend to replace traditional hydraulics and pneumatics with electromechanical solutions, such as Parker’s XFC Series.
Parker’s electromechanical alternative to traditional fluid powered linear actuators, the XFC Series, utilizes a planetary roller screw allowing higher load capacities, increased life and increased tolerance to shock-loading applications.
The XFC Series can support a maximum thrust load to 80,000 pounds providing a seamless substitution from hydraulic to electro-mechanical motion, while offering high levels of control and energy efficiency. Selecting a XFC Series product is easy, and can be done through Parker’s online configurator
Control – When it comes to traditional fluid-powered actuators, high precision and control is hard to come by due to the standard properties of hydraulic oils and other fluid mediums. By substituting a fluid-powered actuator with Parker’s XFC, a high level of precision and control can be achieved. Utilizing the roller screw lead (linear travel per revolution), combined with the revolutions of the motor, the controller can determine the position of the actuator. In many applications it can achieve a repeatability of 0.001” or better.
Maintenance and installation – By utilizing software and monitoring the actuator’s torque within the planetary drives the controller can predict when maintenance will be required. Along those same lines, it is easier to identify abnormalities that may occur well before the point of failure preventing production downtime. Then, in the event of needing to replace a unit, the only maintenance needed to be done is dropping in the new XFC product--there are no hoses, pumps, or other hydraulic system components to worry about.
This plug-and-play ability of the XFC cuts down on installation costs and reduces system components costs of filters, pumps, hoses, etc. It is important to remember that although hydraulics may be lower cost upfront, long-term maintenance costs and higher installation costs significantly increase the total cost of ownership.
