IMI Norgren RA/192125/JM/40 Cylinder - ISO 21287
Part Number: RA/192125/JM/40
Quick Summary
ISO Compact double acting cylinder RA/192125/JM/40 provides reliable linear actuation for automated packaging and assembly lines. Engineers often struggle with high-friction seals, inconsistent stroke, and downtime under load changes. This model conforms to ISO 21287; features a magnetic piston as standard; and uses low-friction, long-life seals to extend service intervals. The rugged anodised aluminium cylinder barrel paired with a martensitic stainless steel piston rod resists wear in demanding environments. Its compact footprint, G1/4 port, and capability for flush-mounted switches simplify integration into standard automation cells, reducing installation time. Designed for compressed air systems, it supports repeatable performance across packaging, plastics handling, and lightweight assembly applications.
