FAQs
The RM/950/300 supports an extensive range of mountings due to its standard tie-rod design and compatibility with the Martonair RM/900 family. This simplifies installation in new or retrofit projects and helps ensure proper alignment and load distribution across cycles. When selecting mounts, verify stroke clearance and cylinder end fittings to prevent binding under load.
The RM/950/300 operates at 2 to 10 bar (29 to 145 psi) and uses a G1/2 port size. This combination delivers reliable actuation for heavy-duty applications while remaining compatible with common pneumatic distributors and valve manifolds. Ensure your air supply is clean and dry to maintain performance over time.
Yes. With a 5" bore and a theoretical 7600 N force, the cylinder can move substantial loads. The adjustable cushioning reduces impact at end-of-stroke, improving repeatability and reducing wear. For precision tasks, ensure proper alignment and optimize cushioning settings to minimize backlash and vibration in the system.
The data provided does not list specific certifications. For procurement, verify CE marking if you operate in Europe, IP ratings for ingress protection in your environment, and any SIL or functional-safety considerations your risk assessment requires. Always confirm these certifications with the supplier prior to purchase.
Service kits are available for RM/900, denoted QM/950/00, and are compatible with RM/950/300 platforms. Kits typically include seals and cushioning components to maintain performance and extend service life. Plan regular maintenance checks and stock common wear items to minimize downtime during scheduled maintenance windows.
