Service kits for RM/900, 6"
Feature: A 6 inch bore tie rod cylinder provides substantial actuation force for heavy loads. Business Impact: The higher force enables fewer cycles and more consistent punch or clamp strokes, boosting overall line throughput. Application: Ideal for stamping, forming, die-casting, or robotic tooling where controlled, high‑load linear motion is essential. Feature: The anodised aluminium barrel combined with a stainless steel piston rod delivers rugged durability and corrosion resistance. Business Impact: Longer service life reduces spare-part costs and maintenance downtime in challenging environments. Application: Suitable for packaging lines, material handling, and general automation in factories with dust, moisture, or washdown exposure. Feature: Adjustable cushioning provides end‑of‑stroke deceleration and impact control. Business Impact: Controls machine wear, protects tooling, and improves part quality during high-speed cycles. Application: Particularly beneficial in end‑of‑travel positioning in automated assemblies, clamps, and presses. Feature: G1/2 port and a wide 2–10 bar operating range support flexible system integration. Business Impact: Allows straightforward compatibility with standard factory air systems, reduces customization, and improves energy efficiency by avoiding over‑pressurization. Application: Retrofit projects and new lines across robotics, conveyance, and pneumatic actuation in manufacturing. Feature: Non‑magnetic piston rod design complements magnetic sensing and cross‑system compatibility within RM/900 family. Business Impact: Improves sensor reliability and maintenance predictability when combining with magnetic or electronic position sensors. Application: Use in automation cells requiring precise sensing and robust linear motion in metalworking and packaging.

FAQs
The RM/960/265 offers extensive mounting options designed to fit standard industrial layouts and the broader RM/900 family. This compatibility enables straightforward retrofits and consistent alignment with existing tooling and frames. When selecting a mounting method, consider end‑of‑stroke cushioning placement, available tie‑rod arrangements, and the space constraints of your automation cell to maintain precise alignment and repeatable performance.
This cylinder is designed for compressed air with an operating pressure range of 2 to 10 bar (29 to 145 psi) and operates effectively between -20 and 80 °C (-4 to 176 °F). For critical applications, verify cooling/venting requirements in your enclosure and ensure compatible lubricants or dry air supply to maintain consistent performance and prevent wear.
Yes. The 6 inch bore provides substantial theoretical force (10887 N), supporting high‑load stamping, forming, and clamping tasks. The adjustable cushioning helps control impact at end‑of‑stroke, reducing tooling wear and improving part quality. For best results, pair with appropriate end‑of‑travel sensors and mountings to ensure repeatable positioning in high‑cycle environments.
The provided data does not explicitly list CE, SIL, or IP ratings. In regulated settings, verify certification status with the supplier or through formal documentation. When selecting for safety‑critical or IP‑rated environments, request the latest datasheet and third‑party test reports to confirm conformity, installation requirements, and any regional compliance considerations.
Norgren provides service kits and support for RM/900‑series components, including QM/960/00 service kits for RM/900, 6" cylinders. Regular maintenance should include seal kit replacement, cushioning adjustment checks, and rod/end‑cap inspection to prevent leakage and reduce downtime. Leveraging these kits in a planned maintenance schedule can extend service life and stabilize total cost of ownership.
