FAQs
For reliable installation, ensure proper alignment of the tie-rod mounting, verify port plumbing using a G3/4 connector, and confirm that operating pressure remains within 2–10 bar. Use compatible mounting accessories from the RM/900/Martonair family and set the adjustable cushioning to suit your cycle time and shock requirements.
Yes. With a theoretical force of 19,417 N, this 8" bore cylinder provides substantial thrust for demanding tasks such as heavy-duty material handling and clamping. Ensure your control system and pressure supply can sustain peak loads, and select appropriate cushioning to manage impact and wear during rapid cycling.
Industries including automotive, packaging, material handling, and heavy machinery automation benefit from the RM/980/380. The long stroke enables extended reach in pick-and-place and insertion tasks, while the large bore delivers necessary force for aggressive actuation in rugged environments.
Yes. The RM/980/380 features adjustable cushioning to fine-tune deceleration and reduce shock on end-of-stroke. It also uses a non-magnetic piston rod and an anodised aluminium barrel, delivering durability, corrosion resistance, and compatibility with proximity sensors in clean or controlled environments.
This cylinder sits in the RM/900 range family and is supported by the QM/980/00 service kit line, facilitating scheduled maintenance and quick part replacement. To minimize downtime, verify mounting compatibility and stock common wear parts, ensuring spare kit availability for periodic service and line upgrades.
