As the patent holder, CYTEC has been manufacturing core pull locking cylinders, block cylinders, as well as locking cylinders and stop cylinders for a wide variety of applications for more than 30 years, from mechanical and plant engineering to the plastics processing industry.
Hydraulic and pneumatic cylinders with integrated positive locking device
The CyLock locking cylinder holds movable loads in one or both final positions with positive locking. The integrated locking mechanism automatically engages when the cylinder reaches its final position, providing fail-safe operation even in case of power loss.
