FAQs
RM/92020/M/70 uses standard M5 porting and is designed to be compatible with the RM/92000/M family accessories. When retrofitting, verify porting adapters, mounting brackets, and sensor interfaces to ensure seamless integration with your existing Norgren components and valve manifolds. This simplifies installation and reduces modification time on the shop floor.
The RM/92020/M/70 has a 20 mm bore with a theoretical force of 188 N. It operates over a pressure range of 1 to 10 bar (14 to 145 psi). For duty cycle planning, ensure your control system can sustain repeatable actuation within these limits, accounting for friction and load dynamics in your application.
The unit uses an anodised aluminium barrel and a stainless steel piston rod, delivering corrosion resistance. However, the data does not specify an IP rating. For wash-down or humid environments, confirm the required IP rating and apply appropriate protection or enclosures per your plant standards. Use of the magnetic piston supports reliable sensing in these conditions when correctly integrated.
Yes. The magnetic piston enables straightforward position sensing using magnetic switches or sensor assemblies without additional mechanical hardware. This capability supports closed-loop control, improves repeatability, and simplifies wiring for inline quality checks or automated feedback in packaging and assembly lines.
The cylinder employs a low-friction, long-life seal design, which reduces wear and extends maintenance intervals. Combined with a non-corrodible construction, you can expect lower downtime and stable performance at high cycle rates typical of assembly, pick-and-place, and rapid insertion tasks. Always monitor seal wear and perform periodic lubrication as per the datasheet recommendations.
