The 19000 series high-resolution linear actuator by HaydonKerk, Waterbury, CT,  is a 20mm-diam can-stack offering with a 7.5° step angle, resulting in smaller move increments and finer positioning ability.  The 19000 is a high output, compact linear actuator for precision motion applications requiring a small footprint. The high output can-stack line provides high force-to-size ratios and is well-suited for precision medical equipment, scientific instrumentation, advanced optics, and other mechanisms requiring high force in a small package size.
