FAQs
RM/950/J/300 supports a range of mounting options and uses a G1/2 port, enabling straightforward integration with standard industrial frames. When planning installation, verify mounting pattern compatibility with existing RM/900 family components and ensure suitable space for the 5 inch bore and 300 mm stroke to avoid misalignment. Consult the datasheet for step-by-step mounting guidelines and protective layout considerations.
The cylinder operates at 2 to 10 bar (29 to 145 psi) and provides a theoretical force around 7600 N. It features a 5 inch bore and 300 mm stroke, with adjustable cushioning to tailor deceleration. The G1/2 port size supports common pneumatic fittings, making it a reliable choice for high-load indexing, clamping, and transfer tasks in automated lines.
Yes, with a 5 inch bore and 300 mm stroke, RM/950/J/300 delivers substantial thrust suitable for high-load clamping and rapid indexing. The adjustable cushioning minimizes impact, protecting fixtures and improving cycle consistency. For high-velocity requirements, verify system pressure, valve response, and mounting integrity to maintain repeatable performance across cycles.
Check for region-specific certifications such as CE marking and applicable IP ratings, as well as SIL safety standards where safety functions are integrated. While the RM/950/J/300 data highlights rugged construction and material specs, confirm the exact certifications with the supplier or distributor for the specific variant and intended market before deployment.
Maintenance can be supported by the QM/950/00 service kit for RM/900, 5 inch variants, enabling periodic seals, cushions, and routine inspection. Regularly inspect the adjustable cushioning, rod end threading, and port connections, and replace worn components promptly to sustain performance. Align maintenance intervals with operating hours and environmental conditions for consistent uptime.
