The SI50BX85 features a hard-anodized aluminum barrel with chrome-plated steel rod, designed for repetitive high-cycle operations. Its dual-piston seal design ensures 10,000km+ service life under standard conditions. The built-in magnet in piston allows precise position feedback when used with magnetic sensors. Special wiper ring design prevents 98% particle ingress according to ISO 8573-1 class 4.
- Palletizing robot end-effector actuation
- Injection molding machine ejection systems
- Automotive welding fixture clamping
- Food processing conveyor gate control
- Pharmaceutical blister packaging machines
Installation guidelines:
Use locknuts (AS2201-10) for axial load support. For vertical mounting,
maintain 0.5mm minimum clearance between rod end and load. Lubricate
with ISO VG32 hydraulic oil if operating below 0.3MPa. Avoid side load
exceeding 30N (use guide mechanism if necessary).
