Feature → Business Impact → Application: The RM/92020/M/25 uses a compact 20 mm bore and 25 mm stroke to fit tight spaces in automated lines, enabling longer actuator life and more versatile mounting. This yields measurable space savings and reduced hardware costs when retrofitting existing equipment in packaging or assembly cells. Application-wise, the small footprint suits end-of-line pick-and-place stations where frequent actuator cycles are required without compromising stroke. Feature → Business Impact → Application: A low-friction, long-life seal design minimizes wear, extending service intervals and lowering maintenance costs in high-cycle environments such as food, beverage, and consumer electronics packaging. Application: Ideal for continuous duty in demanding factory floors. Feature → Business Impact → Application: A fully non-corrodible specification and anodised aluminium barrel coupled with a stainless steel piston rod enhances longevity in damp or dusty environments, improving uptime and total cost of ownership in heavy-use lines. Application: Suitable for wash-down areas and damp plants with reliable performance. Feature → Business Impact → Application: Magnetic piston enables straightforward sensing and integration with standard control systems, reducing integration time and enabling reliable position feedback in automation cells. Application: Simplifies multi-sensor setups and line synchronization. Feature → Business Impact → Application: Operating range of 1–10 bar and temperature tolerance from -5 to 80 °C provides predictable performance across diverse industrial settings. Application: Works with common compressed-air systems and in environments with varying ambient conditions. Feature → Business Impact → Application: No cushioning option reduces stroke delay and simplifies maintenance for high-speed actuation, ideal for precise, repeatable movements in clamping and gripping tasks. Application: Suitable where fast cycling and repeatable positioning are critical. Feature → Business Impact → Application: The RM/92000/M range supports standard mounting options like foot, flange, and adaptor configurations, facilitating straightforward installation alongside existing cylinders.
