Service kits for RM/900, 5"
The RM/950/M/50 features a proven, rugged design that translates into real-world reliability for demanding production environments; this reduces unplanned downtime and maintenance costs. Its double-acting operation delivers consistent, controllable motion across both extend and retract cycles, which improves cycle timing and placement accuracy in automated lines. With adjustable cushioning, operators can tailor deceleration to protect delicate workpieces and reduce mechanical shock, extending actuator life and downstream component reliability. The 5" bore and 7600 N theoretical force provide substantial push capability while preserving compact envelope, enabling higher line speeds without additional actuators. A magnetic piston enables straightforward position sensing for straightforward PLC integration, while the anodised aluminium barrel and martensitic stainless rod resist wear and corrosion in harsh environments. Compatibility with RM/900 range accessories and QM/950/00 service kits simplifies installation, maintenance, and spare-part availability, driving lower total cost of ownership and faster ROI. In practice, this cylinder suits food & beverage, packaging, and general automation applications where durability and performance are critical.

FAQs
The RM/950/M/50 is designed for versatile mounting with standard RM/900-series fittings and a range of available mounting accessories. Its 5" bore, 50 mm stroke, and G1/2 port size simplify retrofit to existing cylinders, while adjustable cushioning helps align deceleration with current tooling. For best results, match the mounting style to your machine’s stroke guide and verify compatibility with the RM/900 accessory catalog and service kits such as QM/950/00.
Core specs include a 5" cylinder diameter, 50 mm stroke length, double-acting operation, G1/2 port size, operating pressure of 2–10 bar (29–145 psi), and an operating temperature range of -20 to 80 °C (-4 to 176 °F). Theoretical push force is 7600 N, with magnetic piston construction and adjustable cushioning to tailor impact. This combination supports robust performance across industrial automation tasks.
Yes. The double-acting design, rugged materials (anodised aluminium barrel, martensitic stainless rod), and adjustable cushioning make it well-suited for high-cycle packaging lines. The high theoretical force enables rapid actuation, while cushioning reduces downstream wear and bounce, contributing to longer component life and more stable cycle timing in repetitive packaging tasks.
For maintenance efficiency, reference the QM/950/00 service kit designed for RM/900, 5-inch models. Regular inspections should include seal condition, bearing movement, cushioning setting integrity, and check of electrical sensing (magnetic piston). Keeping spare RM/900-compatible components on hand minimizes downtime, and using the service kit helps standardize maintenance activities across multiple Actuators in a line.
Industry-standard compliance for industrial pneumatics typically includes CE-related safety and environmental considerations, with potential IP-rating variants for rugged environments. Confirm exact certifications and ratings for your configuration by consulting the official datasheet and manufacturer documentation, as standards may vary by region, model variant, and installed options. This ensures your installation meets regulatory requirements for your application.
