About the Airtac SAI50 Standard Cylinder SAI50X135
The AirTAC SAI50X135 is a double-acting ISO 15552 profile cylinder delivering 982 N of push force at 0.5 MPa. Its 135 mm stroke is a made-to-order dimension outside the standard 25-800 mm increments, built to exact length for specialized travel requirements. The extruded aluminum barrel omits tie-rods for a clean exterior.
This unit features a standard carbon steel piston rod and PT tapered port threads. Because it lacks a magnet, it does not support reed sensors directly; select an SAI50X135-S variant if CMSE or DMSE switches are needed for position feedback.

Where the Airtac SAI50 Standard Cylinder SAI50X135 Is Used
Clamping Mechanisms
Provides 982 N of push force at 0.5 MPa for securing medium-sized workpieces during machining.
Package Diverters
Uses the custom 135 mm travel to push products off a conveyor belt into secondary packaging lanes.
Material Lifters
Raises and lowers light tooling platforms with a compact stroke tailored to specific machine clearances.
Is the Airtac SAI50 Standard Cylinder SAI50X135 the Right Cylinder?
Choose this 50 mm bore when 40 mm (628 N at 0.5 MPa) is insufficient but 63 mm (1559 N) is oversized. For this 135 mm stroke, side load is minimal, but always verify rod bearing loads. The SAI50X135 is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders.
Note that a plain SAI cylinder will drift or drop if air pressure is lost. If the mechanism must hold a load safely without live pressure, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead of relying on the cushion.
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.
