Electric actuator

linearlead screwstepper

Overview
The 46 mm PM Stepper linear actuator is supplied in External and Kaptive configurations for industrial motion applications. Custom lead screw leads, screw-end machining and bespoke overall lengths are available to simplify machine integration.

Dimensional drawings
Available for External and Kaptive configurations. Dimensional drawings and product images are provided to assist mechanical integration and mounting design.

Speed–thrust curves
Speed vs. thrust characteristic curves are available for applicable lead options and operating voltages to support selection and system-level performance checks.

Options

• Screw end machining: custom end forms and finishes for coupling or mounting requirements
• Teflon coating: low-friction, grease-free lead screw option to extend lifetime and improve thrust compared with standard stainless screws; applicable across lead options and actuator types (External, Non-captive, Kaptive)
