About the Airtac SAI50 Standard Cylinder SAI50X75S
The AirTAC SAI50X75-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 75mm stroke. It generates a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty handling and clamping tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior and saving space.
This specific configuration includes a standard carbon steel piston rod and tapered PT port threads. The -S suffix indicates an integrated magnet for position sensing, allowing seamless mounting of CMSE or DMSE switches in the dual side grooves. For high-temperature environments up to 70 C, the standard TPU seals can be swapped for Viton (H) variants.

Where the Airtac SAI50 Standard Cylinder SAI50X75S Is Used
Part Ejection
Uses the 982N push force at 0.5MPa to reliably knock stamped parts out of a press die within a 75mm stroke.
Package Diversion
Actuates a routing gate on a packaging line, utilizing the 30-800mm/s speed range for rapid product sorting.
Fixture Clamping
Secures workpieces in a machining fixture, using the integrated magnet and CMSE switches to confirm clamp engagement.
Is the Airtac SAI50 Standard Cylinder SAI50X75S the Right Cylinder?
Selecting this 50mm bore over the smaller 40mm version upgrades your push force from 628 N to 982 N at 0.5 MPa, while stepping up to the 63mm bore yields 1559 N. The 75mm stroke is ideal for short, rapid movements. Because the stroke is under 300mm, rod bearing bending stress is minimal, but heavy lateral loads still require an external guide to prevent wear.
As a true ISO 15552 standard cylinder, this model is dimensionally interchangeable with other ISO 15552 cylinders without altering your mounting layout. It utilizes a G1/4 port, an M16x1.5 rod thread, and supports foot (LB) or flange (FA) mounting accessories. If your process loses air pressure and the load must be prevented from drifting, substitute this standard cylinder with the SAIL (air-released lock) or BSAI (clamp-lock) 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 SAI50 Standard Cylinder SAI50X75S FAQ
At an operating pressure of 0.5 MPa, this 50mm bore cylinder provides a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X75-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are standardized for direct interchangeability with other ISO 15552 cylinders. Just ensure your existing setup matches the G1/4 port and M16x1.5 rod thread.
