FAQs
When installing RA/192125/M/40, ensure mounting faces align with the ISO 21287 profile and that the G1/4 port is correctly oriented for your manifold. Check the 125 mm bore and 40 mm stroke to ensure stroke travel fits your available space, and verify clearance for the magnetic switch housing and cushion position. Use compatible brackets and verify fastener torque to prevent misalignment during high-cycle operation.
Key performance specs include a 125 mm bore delivering up to 7363 N theoretical force, 40 mm stroke for precise travel, double-acting operation, buffer cushioning for smooth deceleration, and an operating pressure range of 1–10 bar with a temperature range of -5 to 80 °C. These features support fast cycling, repeatability, and reliable pneumatics in high-rate packaging environments.
Yes. The RA/192125/M/40 is designed to comply with ISO 21287, facilitating interchangeability with other ISO Compact series actuators from IMI Norgren and compatible suppliers. This standardization simplifies stocking, reduces spare part variety, and accelerates line changes or expansions without reengineering mounting or control interfaces.
Maintenance benefits come from long-life seals and low-friction guidance, combined with a robust aluminium housing and martensitic stainless rod. Regular inspection of seals and fittings, along with clean, lubricated compressed air, extends service intervals. The magnetic piston supports non-invasive sensing, reducing wear from external switches and enabling predictive maintenance through sensors.
Industries such as automated packaging, material handling, and assembly lines benefit from the RA/192125/M/40 due to its compact footprint, standardized ISO 21287 interface, and reliable double-acting actuation. The unit is well-suited for line integration where space is constrained, precise positioning is required, and sensor feedback from the magnetic piston is advantageous for quality control and process automation.
