High-precision locking cylinder featuring a fail-safe mechanical brake mechanism activated by air pressure loss. The dual-piston lock design ensures zero drift during vertical operations. Constructed with hard-anodized aluminum barrel and chrome-plated piston rod for enhanced corrosion resistance. Requires ISO 8573-1:2010 Class 3-4-3 compressed air.
- Vertical lifting mechanisms in assembly lines
- Safety locking in press machine tooling
- Position retention in material handling robots
- Emergency stop systems for overhead conveyors
- Precision fixturing in CNC machining centers
Installation note:
Lock function requires separate air circuit (1/2 lock port). Perform weekly lubrication
through rod-end grease nipple using ISO VG32 hydraulic oil. Avoid side load exceeding 50N.
