Linear Actuator is designed to replace existing size 17 units.

Press Release Summary:

Along with force output of 70-260 N and output resolution from 0.0005-0.004 in. per step command, 36 mm G4 linear actuator features adapter plate that lets this 36 mm OD unit replace existing size 17 hybrid stepper motor linear actuators. Optimized teeth geometry and high-energy neodymium magnets promote continuous force output rating, while custom-engineered plastics and size of bearings maximize rotor support and axial load capability. There are 3 configurations available.

Haydon Kerk Motion Solutions Offers an Effective Replacement for Existing Size 17 Linear Actuator Units

WATERBURY, CT - Haydon Kerk Motion Solutions, a premier manufacturer of linear motion products, has released a new version of the popular 36mm G4 linear actuator. This configuration includes a special adapter plate that allows the smaller 36mm OD unit to replace existing size 17 hybrid stepper motor linear actuators.

The performance of the 36mm 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 36mm unit with the integrated size 17 adapter plate easily replaces existing hybrid units by using the same bolt pattern and pilot surface.

Assuming the higher step resolution of the hybrid style actuators isn't required for the application, the 36mm can-stack with the size 17 adapter plate provides the performance and life of the more expensive size 17 units. Force output range of the G4 36mm can stack is from 70N to 260N (16lb to 58lb). Output resolution ranges from 0.013mm (0.0005") to 0.102mm (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% 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 36mm linear actuator is ideal 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 Hayden stepper motor linear actuators, there are three configurations available: Captive, Non-Captive, and External Linear.
