TECHNICAL CHARACTERISTICS
Oil-pneumatic cylinders series 341 are formed by a motor pneumatic cylinder, inside the piston rod there is hydraulic speed control device with fixed limit switch decelerators in the two directions.
bores: 50 – 63 – 80 – 100
fixings: as for cylinders ISO 15552 (only rear)
versions: out-stroke regulation – in-stroke regulation – double regulation – incorporated regulator or panel regulator – multi-turn or single-turn regulation – (magnetic piston on request)
All the versions are available with the following pneumatic control devices: rapid nearing (SKIP), normally open stop (STOP NO), normally closed stop (STOP NC). Electrical control devices on request.
FUNCTIONING CHARACTERISTICS
fluid (hydraulic control): hydraulic oil with constant viscosity ISO VG 37 cSt at 40°C t° -40°C ÷ +80°C
fluid (pneumatic control): filtered air with or without lubrication
max. pressure: 10 bar
temperature: 0°c ÷ 80°c (-20°c with dry air)
SPEED MEASUREMENTS (6 bars)
Minimum controlled speed (single-turn regulator): min. speed = 200 mm/min
Minimum controlled speed (multi-turn regulation): min. speed = 40 mm/min
Maximum controlled speed: max. speed = 6 m/min (with incorporated regulator)
Rapid return speed: S = 20 m/min
