High-precision adjustable stroke cylinder featuring micrometer-style stroke adjustment with locking nuts, enabling ±0.1mm repeatability. The dual-cushion design minimizes end-impact noise below 75dB. Corrosion-resistant construction with IP54 protection rating makes it suitable for humid environments. Requires filtered air (5-40μm) with ISO VG32 hydraulic oil mist lubrication.
- Variable position clamping in CNC jigs
- Material handling with adjustable gripping depth
- Printing press roller engagement systems
- Automated packaging line product ejection
- Semiconductor wafer handling robots
Installation tip:
Allow 15mm clearance around adjustment screws for tool access.
Maximum side load: 25N. For vertical mounting, use rod-down orientation
to prevent seal wear from piston self-weight.
- Loosen both lock nuts (17mm wrench size)
- Rotate adjustment screw clockwise to decrease stroke
- Set desired position using dial indicator (not included)
- Re-tighten nuts to 3.5N·m torque
- Perform 5 test cycles before operation
