- Semiconductor wafer handling equipment
- Automotive welding fixture positioning
- Packaging machine product height adjustment
Installation note:
Always lock adjustment bolts with 1.2-1.5N·m torque after positioning.
Maintain parallel alignment within 0.2mm/m during mounting. Lubricate
adjustment threads with ISO VG32 hydraulic oil monthly.
Avoid continuous operation
at maximum stroke reduction (75mm retracted position) for more than
30 minutes to prevent heat buildup in cushioning zone.
