Roller Screw Technology Why Consider Roller Screw Technology Designers have five basic choices when it comes to achieving controlled linear motion. The table on page 3 gives you a quick overview of what general advantages are associated with each. Because the roller screw technology common to all Exlar linear actuators might not be familiar to everyone using this catalog, allow us to present a general overview. The difference is in the roller screw’s design for transmitting forces. Multiple threaded helical rollers are assembled in a planetary arrangement around a threaded shaft (shown below),...

GS Series Linear Actuators with Integrated Motor Linear Actuator Family The GS Series linear actuator family offers you two grades of actuator to provide cost effective options in order to meet your application’s requirements. View the chart below to compare the GSX and GSM models. All GS Series actuators use a specially designed roller screw mechanism for converting electric motor power into linear motion within the actuator. Planetary rollers assembled around the actuator’s extending rod follow threads which are precisely machined on the inside surface of the actuator’s hollow armature. Linear...

GSX Series Linear Actuators with Integrated Motor Roller Screw Option For applications that require long life and continuous duty, even in harsh environments the GSX Series actuator offers a robust solution. The life of the GSX Series can exceed that of a ball screw actuator by 15X while delivering high speeds and high forces. This compact package has all the advantages that our GS Series offers. Sealed for Long Life with Minimum Maintenance GSX Series actuators have strong advantages whenever outside contaminants are an issue. In most rotary-tolinear devices, critical mechanisms are exposed...

GSX Series Speed vs. Force Curves These charts represent typical linear speed versus linear force curves for the GSX actuators using common brushless motor amplifiers. The GSX Series are compatible with many different brushless motor amplifiers, and differences in the performance ratings of these amplifiers can alter the actuator’s performance. Thus, the curves below should be used for estimation only. (Further information is available by contacting your local sales representative.)

GSX Series Linear Actuators with Integrated Motor GSX Series Lifetime Curves The L10 expected life of a roller screw linear actuator is expressed as the linear travel distance that 90% of properly maintained roller screws manufactured are expected to meet or exceed. For higher than 90% reliability, the result should be multiplied by the following factors: 95% x 0.62; 96% x 0.53; 97% x 0.44; 98% x 0.33; 99% x 0.21. This is not a guarantee and these charts should be used for estimation purposes only. The underlying formula that defines this value is: Travel life in millions of inches, where: C...
