The G4 37000 Series Can-stack stepper motor linear actuator provides high linear-force-to-size ratio. The 36‑mm linear actuator features optimized stator tooth geometry, high-energy neodymium magnets, an oversized output spline, custom-engineered plastics, and larger ball bearings for greater rotor support and high axial-loading capability. Three configurations of the actuator are available: captive, noncaptive, and external linear.Haydon Kerk Motion Solutions Inc., 1500 Meriden Rd., Waterbury, CT 06705, (203) 756-7441, www.haydonkerk.com
