3 3 SCU SCU See pages 6 and 7 for the part numbers The stretching cylinder unit is used to elongate the PET bottle preforms. Using a stroke that varies according to the machine type, the preform is stretched to the lower end of the bottle mold. The unit has an optimized air cushion and front plate fixation. The lubricants used are suitable for contact with food (food class NSF H1). The stretching cylinder unit should only be operated using lubricants approved by Bosch Rexroth. performance data Stroke diameter Min./max. working pressure 290 mm or 400 mm depending on machine type 50 mm 5.3 bar/8 bar Min./max. operating temperature + 5 C/+ 50 C Humidity Medium Max. particle size 5 µm Dew point 70% at 32 C continually Compressed air -20 C (+/- 4 C) Oil content of compressed air Max mg/m 3 Max. speed 2 m/s Valve function 5/2-way valve, ISO size 2 Valve operating voltage Valve power consumption 24 V DC 4.5 W The listed performance data is only an excerpt of the technical data.
