Electric actuator PMX series

linearball screwpiston

Overview
The PMX Series electric cylinders are designed for automation applications that require clean operation and enhanced corrosion resistance. They combine corrosion-resistant materials and precise electric motion control to provide reliable linear actuation in washdown, wet and contamination-sensitive environments.

Key selling points

• PTFE wiper + Viton seal: dual-stage protection and sealing
• Stainless-steel piston rod and head screws for corrosion resistance
• ISO 15552 compatible for straightforward replacement of pneumatic cylinders
• Available sizes: 40 and 63 (nominal operating forces: 900 N and 2,000 N)
• Maximum speeds up to 500 mm/s depending on screw lead

Sealing and corrosion resistance
The PMX protection concept focuses on the piston rod material and front sealing area to deliver protection suitable for washdown, wet and clean production environments.

PTFE (Teflon) wiper and Viton seal
The PTFE wiper removes water, dirt and process residue from the piston rod. The Viton seal behind the wiper forms a second sealing stage to protect the internal cylinder components.

• Dual-stage wiping and sealing design
• Designed for washdown and wet environments
• Protection suitable for clean production applications

Stainless-steel piston rod and head screws
The stainless-steel piston rod and head screws provide a corrosion-resistant mechanical structure for applications exposed to moisture and aggressive media.

• Stainless-steel piston rod
• Stainless-steel head screws
• Suitable for corrosion-prone automation environments

Precision motion and industrial compatibility
The PMX Series integrates iMotion ball screw technology and flexible motor mounting to deliver high positioning accuracy, repeatability and energy-efficient operation adapted to industrial multi-axis systems.

• High-efficiency ball screw technology
• High positioning accuracy and repeatability
• Suitable for synchronized multi-axis systems
• Anti-rotation piston rod
• Energy-efficient, low-maintenance operation

Compatibility and mounting options
ISO 15552 compatibility simplifies replacement of pneumatic cylinders and supports different mounting and motor arrangements.

• Compatible with pneumatic cylinder mounting accessories
• Extended piston rod options
• Custom piston rod thread available
• Inline or parallel motor mounting
