FAQs
Yes. The Roundline design aligns with common ISO/VDMA footprints for 40 mm bore cylinders, and it uses Rc1/8 porting for compatible pneumatic fittings. This simplifies retrofit projects and minimizes custom mounting hardware, reducing installation time.
The theoretical force is 754 N. It operates from 1 to 10 bar (15 to 145 psi) and tolerates temperatures from -10 to 80 °C. For highest performance, ensure the actuator is sized for your load profile and avoid sustained operation at the upper temperature and pressure limits.
Best suited for compact automation tasks such as pick-and-place, assembly, and fixture actuation in packaging lines, machine tending, and tight-space transfer systems. Its magnetic piston enables straightforward sensing, while the stainless steel barrel and rod support durability in demanding environments.
Certifications vary by region and are not explicitly listed in the provided data. Typical requirements include CE and region-specific standards (IP ratings, SIL considerations). Verify the latest datasheet and local compliance requirements to confirm which certifications apply to your installation site.
Benefits include low-friction seals for longer service life, buffer cushioning to reduce impact loads, and a double crimped end-cap design for durability. Stainless steel components resist corrosion, contributing to lower maintenance needs and reduced replacement costs in challenging environments.
