Integrated shock absorption system reduces end-impact noise to <75dB. Optional magnetic piston version (SAIJ40X50-20S/M) available for position sensing. Requires ISO VG32 hydraulic oil lubrication if used in high-cycle (>500CPM) applications.
- Packaging line product positioning gates
- CNC machine tool clamping mechanisms
- Electronic component insertion systems
- Automated welding fixture height adjustment
- Textile machinery tension control devices
Maintenance Tip:
Rotate cushion needles clockwise to increase damping force. For vertical installations,
add 0.5-1mm shim washers under lower mounting bolts to compensate for rod sag.
