A high-precision industrial cylinder featuring anti-rotation rod design and corrosion-resistant construction. The SI40X215S delivers 503N thrust at 0.6MPa (extend) and 456N at retract. Precision honed tube ensures ≤0.2mm/m straightness. Optional magnetic piston version (SI40X215S-M9N) available for position sensing.
- Automated packaging line pusher mechanisms
- CNC machine tool clamping systems
- Automotive welding fixture positioning
- Textile machinery tension control
- Plastic injection molding ejectors
Installation guidelines:
Maintain 0.5–1mm alignment tolerance during mounting. Lubricate with ISO VG32 hydraulic oil
if operating below 3 cycles/minute. For vertical mounting, use rod-down orientation to prevent
condensate accumulation.
- Relubrication interval: 3 million cycles or 12 months
- Wear inspection: Check rod surface roughness (Ra ≤0.4μm)
- Seal replacement threshold: 0.5mm rod play
