Servo-Drive's line of hybrid linear actuators open new avenues for equipment designers who require high performance and exceptional endurance in a very small package. The various patent pending designs use a proprietary manufacturing process, which incorporates engineering thermoplastics in the rotor drive nut and a stainless steel acme lead screw. This allows the motor to be much quieter, more efficient and more durable than the v-thread and bronze nut configuration commonly used in other actuators. Motor life is improved more than 10 times over the traditional bronze nut style - and it requires no maintenance and does not affect the cost. An additional feature is the bearing pre-load adjustment which, unlike other designs, does not protrude from the motor configuration commonly used in other actuators. The HSI hybrid actuators come in six sizes, from 21 mm square to 87 mm square. Each size has three designs available - captive, non-captive and an external linear version. These linear actuators are ideal for application requiring a combination of precise positioning, rapid motion and long life. Typical applications include X-Y tables, medical equipment, semiconductor handling, telecommunications equipment, valve control, and numerous other uses. Sold at competitive prices, this product is an excellent value for incorporation into your next project.
