Horizontal Zeropoint Quickclamping cylinder with piston-catching
Hydraulic release
Cover and piston hardened
Repeat accuracy < 0,005 mm
Size: K20, K40
Explanation:
With our new Zeropoint Quickclamping cylinder with piston-catching, we make the palletizing asier and quicker.
• No search of drilling
• No damage of zero point drilling and nipples
• No risk of injury
Releasing and taking out of the pallet, take place still faster and simpler, because of the linking with the crane which is not more necessary during the release phase
Thanks to the speed of pelletizing, you reduce considerably your pelletizing period and consequently your costs.
Advantages:
• With and without blow out
• Completely in stainless steel
• Applicable in all positions without fit-up aids
• When the mechanism is out of service, the piston-catching stay out, it can be locked, thus the discs spring are not forced.
Can be integrated in:
• Clamping towers
• Clamping angles
• Automatized handling devices
• General mechanical
Note:
As standard, there is a manual or hydraulic advance motion of the piston-catching.
