Precision-adjustable compact cylinder with dual cushion control, featuring a built-in magnet for position sensing compatibility. The hardened stainless steel guide ring ensures minimal friction loss (≤15% theoretical output). Requires ISO 8573-1:2010 class 3-4-3 compressed air with 1-50μm filtration.
- Precision stop mechanisms in semiconductor handling robots
- Clamping force adjustment in CNC fixture systems
- Variable stroke applications in packaging line diverters
- Medical device assembly positioning stages
- Force-controlled pressing operations (with pressure regulator)
Installation protocol:
Align cylinder axis within ±0.5° angular misalignment tolerance.
Lubricate with ISO VG32 hydraulic oil if operating below 0.1 MPa.
Allow 1.5× bore diameter clearance for magnetic sensor installation.
