FAQs
RM/92025/M/20 supports multiple mounting options to fit diverse installations. Nut style N2 (M/P1501/79) is available, along with C-foot mounting for 25 mm bore (QM/90025/21), piston rod clevis (QM/57016/25), stud/adaptor mounting for RM/92000/M and RM/91000/M cylinders (M/P1710/21), and front/rear flange mounting (QM/90025/22). This range enables easy alignment, quick swaps, and reliable stabilization within compact assemblies.
The RM/92025/M/20 operates from 1 to 10 bar (14 to 145 psi). At these pressures, the cylinder provides a theoretical force of 295 N, suitable for mid-load actuation tasks in automated lines. Always verify actual force in your specific system considering porting, frictions, and mounting orientation.
Yes, its low-friction, long-life seal design supports frequent cycling with reduced wear. The magnetic piston allows easy sensing, aiding reliable feedback in high-speed cycles. For extended life, ensure proper lubrication and avoid counterproductive stalling; you can also select appropriate cushioning or mounting to tailor rebound behavior to your cycle rate.
Switch compatibility includes M/50 magnetically operated reed switches with 5 m cable (M/50/LSU/5V) and switch brackets such as M/P72487B for M/50 switches. These options provide straightforward position sensing and integration with common automation controllers, reducing wiring complexity and commissioning time.
Fittings include Pneufit C push-in options like C0K510405 (4 mm tube, M5) and the 90° adapter C02470405 for routing tubing. Additional straight or angled fittings, tubing (PA2-0004100 and PA2-0004025C in natural polyamide), and a tube cutter (M/3314) support flexible installation and maintenance in tight spaces.
