The G4 Canstack linear actuator uses optimized teeth geometry along with high energy neodymium magnets.With higher output force across the entire speed range, the G4 contains the latest custom-engineered plastics, an oversized spline, and larger bearings for greater rotor support and higher axial load capability. The G4 canstack provides high linear force-to-size ratios for precision linear motion in a variety of applications including medical equipment, bar-code scanning, printing equipment, and laboratory instrumentation.Three configurations are available: captive, noncaptive, and external linear.Haydon Kerk Motion Solutions Inc., 1500 Meriden Rd., Waterbury, CT 06705, (203) 756-7441, www.haydonkerk.com
