The SI40BX5 medium-duty pneumatic cylinder features a double-acting design with enhanced lateral load capacity through integrated guide slots. Its precision honed tube (Ra≤0.4μm) ensures smooth operation with ≤0.5mm lateral play. The multi-layered sealing system combines wear-resistant buffer seals with low-friction piston seals, achieving >2,000km service life at 0.5MPa.
- Packaging machine clamping mechanisms
- CNC machine tool door actuators
- Automotive welding fixture positioning
- Conveyor diverters in logistics systems
- Food processing equipment (corrosion-resistant versions)
Installation guidelines:
For vertical installations, use rear flange mounting (MP2) with 50% reduced maximum thrust.
Maintain 0.5mm minimum alignment tolerance between rod and load. Lubricate with ISO VG32 hydraulic oil
if operating below -10℃. Annual seal replacement recommended for >3,000 cycles/day applications.
