The Roundline cylinder leverages a 20 mm bore and 50 mm stroke to deliver a compact footprint that saves space by up to 20% compared to equivalent basic-length ISO/VDMA cylinders, allowing tighter machine layouts and easier piping routing. This translates into faster line changes and lower cabinet and panel costs, especially in tight assembly cells and pick-and-place stations. The single-acting design simplifies valve integration and reduces energy consumption, improving overall cycle efficiency and control reliability in compressed air systems. Buffer cushioning smooths deceleration at end-of-stroke, reducing vibration transfer to fixtures and extending tool life in high-cycle applications. A magnetic piston enables straightforward sensor feedback for position monitoring, simplifying integration with PLCs and safety interlocks in automated lines. Stainless steel barrel and martensitic piston rod deliver corrosion resistance and longevity in demanding environments, reducing maintenance intervals in food & beverage, packaging, and general automation. Rc1/8 port sizing aligns with standard air supply components, while operating pressure of 2–10 bar covers typical industrial plants. The RT/57300/M range and Roundline series ensure compatibility with a broad family of actuators, easing system scaling and spare-part planning. Cushioning and hard-wearing end caps further support reliable performance, even under rapid cycling.

FAQs
Begin by verifying mounting compatibility and alignment to prevent side loading. Use the Rc1/8 port for the air supply and connect to a suitable push-button or solenoid valve. Ensure the end caps are correctly oriented for single-acting operation and secure mounting with appropriate brackets. After installation, check for smooth travel and verify sensor feedback from the magnetic piston for reliable control.
Ideal for compact automation tasks such as pick-and-place, part feeding, simple clamping, and sequencing operations in tight spaces. The 20 mm bore and 50 mm stroke provide precise, repeatable motion, while buffer cushioning minimizes impact loads. Its magnetic piston supports easy sensor integration for position feedback in PLC-controlled lines.
This model operates from 2 to 10 bar (29 to 145 psi) and is rated for temperatures from -10 to 80 °C (14 to 176 °F). It uses compressed air as the medium and features an Rc1/8 port for standard pneumatic hookups, making it compatible with common plant air systems and regulators.
The RT/57320/M/50 is designed for industrial use with CE-ready standards and typical safety-integrated environments. For SIL-specific applications, perform a risk assessment and verify compatibility with your safety system. The magnetic piston and robust mechanical design support integration with safety interlocks and PLC-based guards in compliant installations.
The combination of a stainless steel barrel, martensitic piston rod, and low-friction, long-life seals reduces wear and extends service intervals in harsh environments. Buffer cushioning minimizes shock loads, protecting fixtures and improving cycle life in high-speed applications. The magnetic piston enables straightforward sensor monitoring, supporting proactive maintenance and uptime improvements.
