FAQs
The RM/980/675 uses standard G3/4 porting, enabling straightforward connections to common pneumatic manifolds and tubing. Verify pressure rating (2–10 bar), ensure compatible mounting brackets, and use appropriate fittings to match your existing RM/900 family components. This reduces installation time and simplifies future upgrades.
The cylinder operates from 2 to 10 bar (29 to 145 psi). This range supports flexible actuation speeds and forces while maintaining control over cushioning and end-of-stroke impact in high-cycle applications.
The RM/980/675 provides a theoretical force of 19417 N at rated conditions. This substantial force supports heavy-duty material handling, clamping, and lifting tasks typical in demanding industrial lines.
Yes, the unit is non-magnetic. This property minimizes magnetic interference with nearby sensors and equipment, which is beneficial in precision automation environments and applications requiring sensitive measurement or positioning systems.
For RM/900 series components up to 8" bore, service kits are available as QM/980/00. These kits support routine maintenance and seal replacement, helping to extend service intervals and maintain consistent performance on heavy-duty cylinders.
