About the Airtac SAI63 Standard Cylinder SAI63X1200
The AirTAC SAI63X1200 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 1200mm stroke. It delivers a push force of 1559 N at 0.5 MPa, making it well-suited for long-travel material handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting accessory installation.
This model incorporates standard carbon steel piston rod material for robust daily operation. For environments requiring position feedback, the barrel features integrated sensor grooves on both sides, ready to accept CMSE or DMSE switches when a magnet is specified. The cylinder uses adjustable air cushions at both ends to decelerate the piston effectively over this extended travel distance.

Where the Airtac SAI63 Standard Cylinder SAI63X1200 Is Used
Extended Stroke Transfer
Ideal for pushing products or pallets across long distances on a conveyor line where a 1200mm travel distance is required to bridge machine gaps.
Automated Storage Retrieval
Provides the 1559 N force and long reach necessary to extract totes from high-density storage racks in automated warehousing systems.
Large Assembly Press
Handles the actuation of large jigs or fixtures over a wide working envelope, utilizing its 0.15-1.0 MPa operating pressure range for consistent clamping.
Is the Airtac SAI63 Standard Cylinder SAI63X1200 the Right Cylinder?
This 63mm bore provides 1559 N of thrust at 0.5 MPa; step down to a 50mm bore (982 N) for lighter loads or up to an 80mm bore (2513 N) if your application requires greater push force. Because the stroke is 1200mm, managing side load is critical—an unsupported rod of this length is highly susceptible to bending under lateral stress. Employ an external guide rail or a guided cylinder mechanism to protect the rod bearing and ensure smooth linear travel.
As a dimensionally interchangeable ISO 15552 unit, this cylinder serves as a direct replacement for other standard profile cylinders. To match this exact configuration, specify the 63mm bore, 1200mm stroke, PT G3/8 port, TC trunnion or FA flange mounting, and no magnet (-S) if sensors are not required. Note that this standard cylinder does not hold the load if air pressure is lost; for position holding without live pressure, consider the SAIL locking variant.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI63 Standard Cylinder SAI63X1200 FAQ
