pneumatic and oil-pneumatic cylinders

TECHNICAL CHARACTERISTICSOil-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 CHARACTERISTICSfluid (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)
