Linear actuator -- Haydon Kerk Motion Solutions Inc.

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.
