FAQs
The RM/980/Y/420 is part of the RM/900 family and uses QM/980/00 service kits designed for RM/900, 8 inch bore variants. These kits streamline seal replacement and cushioning adjustments, supporting rapid maintenance and uptime. Always confirm part numbers against the datasheet to ensure mounting and compatibility.
Operating medium is compressed air. It supports 2 to 10 bar (29 to 145 psi) and temperatures from -20 to 80 °C (-4 to 176 °F). With an 8 inch bore and 420 mm stroke, it delivers up to 19417 N of thrust under nominal conditions, making it suitable for heavy-load applications.
The 8 in bore and 420 mm stroke provide substantial thrust for stamping, clamping, and material handling in heavy-duty automation. The adjustable cushioning protects downstream equipment and extends cylinder life, while non-magnetic construction minimizes interference with sensors and electronics in automated lines.
Adjustable cushioning lets you tailor end-of-stroke impact to your load and cycle rate, reducing shock, vibration, and premature wear of seals and mounting hardware. This is particularly beneficial in high-cycle or precision applications where smooth motion improves product quality and uptime.
Yes. The piston rod is stainless steel (martensitic) and the design is non-magnetic, reducing magnetic interference with nearby sensors and electronics. This makes the RM/980/Y/420 well-suited for automation cells, robotics, and precision assembly where magnetic noise must be minimized.
