About the Airtac SAI100 Standard Air Cylinder SAI100X135S
The AirTAC SAI100X135-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100 mm bore unit is built to handle substantial loads. The 135 mm stroke provides extended travel for pressing, lifting, and clamping operations. As a genuine AirTAC component, it guarantees reliable performance in demanding industrial environments.
This configuration includes a standard carbon steel piston rod for high tensile strength and a built-in magnet (-S) for position sensing. The extruded aluminum barrel features sensor grooves on both sides, allowing direct mounting of CMSE or DMSE reed switches without additional brackets. It utilizes a PT tapered port thread and supports adjustable air cushions at both ends to decelerate heavy payloads smoothly.

Where the Airtac SAI100 Standard Air Cylinder SAI100X135S Is Used
Heavy-Duty Pressing
Provides the necessary 3927 N thrust at 0.5 MPa for seating bearings, stamping light-gauge metal, and assembling heavy components.
Pallet Diverting
Drives robust routing arms or stops on high-mass conveyor lines, using the 135 mm stroke to redirect heavy pallets smoothly.
Automated Clamping
Secures large workpieces during CNC machining or welding, relying on adjustable air cushions to prevent end-of-stroke impact.
Is the Airtac SAI100 Standard Air Cylinder SAI100X135S the Right Cylinder?
Selecting this 100 mm bore is ideal when a 80 mm bore (2513 N at 0.5 MPa) lacks the necessary thrust for your application. If your system requires less force and faster cycling, stepping down to an 80 mm bore is recommended. Because the stroke is 135 mm, side-load stress on the rod bearing is moderate, but ensuring proper load alignment remains critical for maximizing seal life.
This model functions as a direct drop-in replacement for other ISO 15552 profile cylinders, matching standard mounting dimensions. To complete your assembly, pair it with a TC trunnion or FA flange mounting accessory, ensure your pneumatic plumbing matches the G1/2 port, and utilize the -S magnet capability with DMSE sensors. Note that standard double-acting cylinders drift if air pressure is lost; use a SAIL variant if the system requires mechanical load holding.

- ✓ 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.
