The TWG40X20C features a unique dual-locking mechanism combining pneumatic holding force with mechanical wedges, delivering 3x higher holding force than standard cylinders. Its compact profile (40% shorter than conventional models) enables integration in space-constrained automation systems. The hardened stainless steel stopper block withstands lateral forces up to 300N, making it ideal for precision part positioning and crash protection.
- Automated conveyor line part stoppers
- CNC machine tool workpiece clamping
- Robotic welding fixture positioning
- Pharmaceutical blister packaging indexers
- EV battery module assembly stations
Installation protocol:
Maintain 0.05–0.1mm clearance between stopper block and target surface during alignment.
Use locknuts with 1.2–1.5Nm torque for mounting. Lubricate with ISO VG32 hydraulic oil
if operating below 1 cycle/second. Avoid side-load exceeding 10% of max thrust.
