FAQs
The RT/57240/MC/320 uses Rc1/8 port sizing and Roundline mounting compatibility typical of Norgren’s double-acting cylinders. For installation, pair the cylinder with standard end blocks and appropriate clevis or rod cleat fittings to achieve secure linear actuation in limited-space layouts. Ensure your manifold pressure is within 1–10 bar and that the mounting orientation does not interfere with the magnetic piston sensors.
The cylinder provides a theoretical force of 754 N at the 40 mm bore with a 320 mm stroke. Buffer cushioning helps control deceleration at the end of stroke, reducing impact loads, extending seal life, and minimizing vibration. This makes it suitable for high-cycle applications where smooth stopping is critical to part placement accuracy and machine longevity.
Yes. The cylinder is designed for 1–10 bar compressed air and features low-friction seals for dependable, repeatable actuation at typical packaging line speeds. The 320 mm stroke combined with a 40 mm bore provides a balance of rapid travel and controlled motion, supporting reliable pick-and-place and positioning tasks in fast packaging environments.
Certification details are not specified in the provided data. When selecting for regulated environments, confirm CE marking, IP rating variants, and any regional compliance with your Norgren distributor or engineering team. The stainless barrel and magnetic piston are aligned with common industry practices, but exact certifications depend on the configuration and regional requirements.
The unit uses low-friction seals and a high-strength end-cap design to extend service life, while a stainless steel barrel and martensitic piston rod resist corrosion and wear. Buffer cushioning reduces impact loads, potentially lowering maintenance frequency and replacement costs in high-cycle applications.
