A heavy-duty locking cylinder featuring instant position retention capability through its spring-engaged wedge locking mechanism. The SULF series combines precision machining with wear-resistant coatings, delivering ±0.2mm repeat positioning accuracy. Optimized for vertical load applications requiring fail-safe position holding during power/pneumatic failures. Requires 40μm filtered air and monthly lubrication (ISO VG32 recommended).
- Vertical press brake tool positioning systems
- Automated warehouse lift-and-hold mechanisms
- Robotic welding fixture clamping
- Die-casting machine safety interlocks
- Overhead conveyor emergency stops
Installation note:
Locking mechanism engages only in fully extended position.
Ensure 0.5mm minimum clearance between lock bracket and mating surface.
Avoid side loads exceeding 50N during operation.
