High-precision adjustable stroke cylinder featuring dual cushioning control and enhanced side load resistance. The 50SFA variant includes magnetic piston for position sensing compatibility. Precision-machined rod guide bushing ensures minimal friction variation (±10% max). Optimized for applications requiring repeatable mid-stroke positioning adjustments without mechanical stops.
- Packaging line product height adjustment mechanisms
- Semiconductor wafer handling positioners
- Automated door stroke limitation systems
- Press tooling with variable depth control
- Textile machinery tension adjustment
Installation guidelines:
For optimal performance, maintain 0.05-0.15mm clearance between rod and bushing.
Use locknuts (included) for stroke limiter fixation. Lubricate with ISO VG32 hydraulic oil
if operating below -10℃. Avoid angular misalignment exceeding ±2°.
