Description
At 6 bar the DGRC-GF-25-20-PA turns a theoretical 295 N into a guided linear motion over 20 mm, with a 25 mm piston.
Benefits
- Plain-bearing guide: guide rods in plain bearings, transverse force Fy up to 663 N
- Force: 295 N advance and 247 N return at 6 bar (theoretical)
- Cushioning: elastic cushioning rings at both ends, impact energy up to 0.3 J
- Moments: Mx up to 21.22 Nm, My/Mz up to 9.28 Nm
- Speed: up to 0.8 m/s
- Torsional backlash: only 0.045°
Applications
The DGRC-GF-25-20-PA suits lifting, stopping and pushing tasks in conveyor systems and fixture building. Operating medium for the DGRC-GF-25-20-PA is compressed air to ISO 8573-1:2010 [7:4:4], permitted ambient temperature -10 to 60 °C, any mounting position. For electronics, precision or battery production, this 25 mm version offers reduced Cu/Zn/Ni content for lithium-ion battery production (F1a).
