High-performance industrial cylinder with chromium-plated piston rod and precision honed tube. Features dual cushion adjustment screws for smooth end-of-stroke deceleration. The SAI63AX850S combines heavy load capacity (up to 3.1kN) with extended stroke precision, using corrosion-resistant aluminum alloy construction for harsh environments.
- Material handling systems requiring long-stroke actuation
- Press machinery vertical load operations
- Automotive assembly line positioning devices
- Packaging equipment vertical lifting mechanisms
- Plastic injection molding machine ejectors
Installation note:
Maintain 0.5–1mm alignment tolerance during mounting. For vertical installations exceeding 45° angle,
use guide mechanisms to prevent side load. Lubricate rod weekly in high-cycle applications (>500,000 cycles/year).
Critical parameters:
Max side load capacity 150N, acceleration limit 5m/s².
Not suitable for horizontal mounting with unsupported loads >25kg.
Use M6 mounting bolts with 12.9 grade minimum.
