4 Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice. General These cylinders are built according to ISO 21287 standards. New barrel profile has two sensor slots on the three sides (Ø20 andØ25 one slot) suitable for sensors 1580._, MRS._, MHS._ series housing, without need for adaptors. Versions with end stroke adjustable pneumatic cushioning are also available, allowing adjustments to deceleration and keeping the required overall dimensions according to ISO21287. For fixing operation is possible to use the four threaded holes on the end covers, or screws in body holes, alternatively all the fixing devices of UNITOP RU-P/6-P/7 (Ø20 andØ25) and ISO15552 (fromØ32 toØ100) series.

Use hydraulic oils H class (ISO Vg32) for correct continued lubrication. Our Technical Department will be glad to help. 4.139
