Notes
From type HK HFR2S 060... piston safeguard by means of safety bolt
Piston speed based on standard seals: Max. 25 m/min - 0.42 m/sec.
Piston speed to the end positions: max. 6 m/min - 0.10 m/sec.
For these standard cylinders, it is recommended not to weld any fastenings to the cylinder liner (e.g. cardanic mountings) as this could distort it.
