Festo
The Festo 151121 is a double-acting industrial component featuring a 25 mm piston diameter, a 25 mm stroke, and an M10x1.25 piston rod thread with an oval piston providing torsion protection up to a max torque of 0.8 Nm and a max angle of rotation of plus or minus 2.4 degrees. Operating on compressed air according to ISO 8573-1:2010 [7:4:4] within a 1 bar to 10 bar pressure range and -20 degrees C to 80 degrees C ambient temperature, this unit achieves a theoretical retracting force of 247 N at 6 bar and incorporates adjustable pneumatic cushioning at both ends with a 17 mm cushioning length. Position sensing is accomplished via proximity switch, and the assembly is rated for moderate corrosion stress with CRC 2 and VDMA24364-B2-L LABS conformity.
