About the Airtac SAI50 Standard Cylinder SAI50BX260S
The AirTAC SAI50X260-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 260mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it a robust choice for medium-duty automation. This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a -S magnet for direct mounting of CMSE or DMSE sensor switches along the dual barrel grooves.
Genuine AirTAC engineering ensures reliable operation across a 30-800 mm/s speed range. The extruded aluminum barrel design omits tie-rods for a clean exterior while maintaining strict dimensional interchangeability per ISO 15552. Adjustable air cushions at both ends absorb impact, and PT tapered ports ensure a secure pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50BX260S Is Used
Package Diverting
Ideal for diverting medium-weight packages on conveyor lines, utilizing the 982N push force and 260mm stroke to push products cleanly into sorting lanes.
Material Pressing
Provides consistent downward pressure for light assembly tasks or component pressing, where the SUS304 rod offers excellent moisture resistance.
Pallet Stopper
Acts as a reliable pneumatic stopper for pallets or workpieces in motion, with the adjustable end cushions absorbing the kinetic energy safely.
Is the Airtac SAI50 Standard Cylinder SAI50BX260S the Right Cylinder?
If you need less force, the neighboring 40mm bore provides 628N push at 0.5 MPa; stepping up to the 63mm bore yields 1559N. At 260mm stroke, the extended rod is susceptible to bending under side loads. We recommend using an external guide rail or a guided cylinder to prevent premature rod-bearing wear.
This model is dimensionally interchangeable with other ISO 15552 profile cylinders. To match this exact unit, specify a 50mm bore, 260mm stroke, PT G1/4 ports, FA/FB flange or TC trunnion mounting, and the -S magnet option. Remember that a standard SAI cylinder will drift and drop its load if air pressure is lost; use the SAIL locking variant if your application requires fail-safe position holding.
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 SAI50 Standard Cylinder SAI50BX260S FAQ
At 0.5 MPa, this double-acting cylinder provides 982N of push force and 825N of pull force. At 0.7 MPa, the push force increases to 1374N.
No, a standard SAI cylinder cannot hold a load without constant air pressure. If power is lost, the piston will drift. For vertical load holding, use the SAIL variant with an air-released lock or an external rod lock.
