Haydon Kerk Motion Solutions, a manufacturer of linear motion products, has released a new version of the popular 36 mm G4 linear actuator. This configuration includes a special adapter plate that allows the smaller 36 mm OD unit to replace existing size 17 hybrid stepper motor linear actuators. The performance of the 36 mm G4 linear actuator not only exceeds the performance of comparable size can stack actuators in the marketplace but also meets the performance of the larger hybrid size 17 single stack actuators. The 36 mm unit with the integrated size 17 adapter plate easily replaces existing hybrid units by using the same bolt pattern and pilot surface. Force output range of the G4 36 mm can stack is from 70 N to 260 N (16 lb to 58 lb). Output resolution ranges from 0.013 mm (0.0005") to 0.102 mm (0.004") per step command.

The G4 linear actuator architecture employs the latest technologies to extend reliability and meet higher performance requirements.The design utilizes optimized teeth geometry along with high-energy neodymium magnets that result in a higher continuous force output in a small package. With 20 percent higher output force across the entire speed range, compared with other designs of similar size, the G4 also contains the latest custom-engineered plastics and larger bearings for greater rotor support and higher axial load capability.

The 36 mm linear actuator is suitable for applications that include medical equipment, bar code scanning devices, printing equipment, laboratory instrumentation and other mechanisms requiring high force in a small package. As with other Haydon stepper motor linear actuators, there  are three configurations available: Captive, Non-Captive, and External Linear.
