Linear Actuators With Different Specifications
Modern linear actuator manufacturers have been coming up with products that can be easily configured and downloaded by the users. For this, actuators are designed with considerations on factors like actuator length, motor voltage, motor step angle, screw resolution and several other design parameters.
Actuators in the present scenario can be seen coming with different specifications which will be discussed in this article.
Actuators with gearbox and servomotor
The kind of actuators having gearbox and servomotor comes featured with track roller guidance system to moderate light loads and a ball monorail guidance system to control heavy loads. Gearbox is known to come with low mass along with high dynamic characteristics and is greased for life. Adding to it, servomotor is known to have low mass moment of inertia.
And the advantages of this specification based actuators include they are ready to fit and come with unlimited stroke lengths. One of the economic advantages is that the design is very compact as they come with a reduced number of components.
Actuators with track roller guidance system
With track roller guidance system, the actuators are considered complete units that are comprised with an aluminum support rail along with rolled-in steel shafts. Other qualities include they come with planetary gearbox, servomotor with two power classes, toothed belt drive having return units and much more.
This type of actuators can be used to support loads about all axes. They come with the features of wiper units and lubrication which means that they can easily protect the raceways. The track rollers are greased for life and make the products maintenance-free. With these specs, the actuators are suitable for high accelerations and speed based applications in different fields of industry.
Apart from these, actuators come with several other specifications for wider range of linear motion applications. Performance characteristics of different specification based actuators express that they can perform wide range of functions that involves motion control, positional current and speed control.
They are designed to support corrosion resistance, washdown protection and bacterial growth prevention. Manufacturers produce them by considering offering ideal solution in environments where contamination is not acceptable. This is the reason the products are developed from stainless steel to meet the requirements in medical field or other.
To support loop positioning applications, it has become simple to get linear actuators that are designed by focusing on factors like position, velocity as well as acceleration control.
