Precision-engineered compact cylinder featuring twin adjustable pneumatic cushions for controlled deceleration. The swivel base (type S) allows ±5° angular adjustment during installation. Hard anodized barrel resists scoring in high-cycle applications (up to 20M cycles @ 500mm/s). Integrated cushion locknut prevents accidental adjustment drift.
- Precision stop mechanisms in PCB assembly robots
- Clamping force control in injection molding ejectors
- Variable stroke positioning for semiconductor handlers
- Shock-sensitive material handling systems
- Packaging machine product height adjustment
Maintenance tip:
Achieve optimal cushioning by turning adjustment screw 15° increments while monitoring with a pneumatic pressure gauge. Maintain 0.3–0.5μm Ra surface roughness on rod contact surfaces.
Critical note:
Avoid side loads exceeding 15N·m. Use with rod guide kits when lateral forces exceed 5N. Not compatible with pulsating air supplies above 3Hz.
