A high-precision double-acting pneumatic cylinder featuring wear-resistant construction and precision honed tube. The dual adjustable cushioning system minimizes end-impact noise (≤65dB) while maintaining positioning accuracy within ±0.5mm. Optimized seal geometry ensures ≤0.5mm/s creep speed under load. Requires 40μm filtered air with ISO 8573-1:2010 Class 4.3.2 air quality.
- Cartesian robot positioning systems
- Plastic injection molding ejectors
- CNC machine tool clamping mechanisms
- Automated conveyor sorting gates
- Pharmaceutical blister packaging machines
Installation guidelines:
Maintain ≤0.1mm/m alignment tolerance during mounting. For vertical installations,
use counterbalance valves when handling loads >15kg. Lubricate through air port
using ISO VG32 turbine oil every 8,000km of cumulative stroke travel.
Critical note:
Avoid side load forces exceeding 35N. For eccentric loads,
use guided cylinder configurations. Maximum permissible
rod-end play: 0.8mm radial deflection.
