About the Airtac SAI50 Standard Cylinder SAI50X220
The AirTAC SAI50X220 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 220mm stroke. Because 220mm falls outside the standard stroke increments, it is manufactured as a non-standard, made-to-order length. It delivers a theoretical push force of 982 N at 0.5 MPa, making it well-suited for mid-range actuation tasks.
This unit features a standard carbon steel piston rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for easy position detection if a magnet is added later. For high-temperature environments up to 70 C, TPU seals are standard, though Viton (H) options are available upon request.

Where the Airtac SAI50 Standard Cylinder SAI50X220 Is Used
Package Diverting
Provides the 982 N push force needed to divert heavier packages on a sorting line over a 220mm extension distance.
Clamp Actuation
Extends 220mm to position clamping jaws on large machined parts, utilizing the adjustable cushion to prevent impact damage.
Pallet Stopping
Acts as a pneumatic stop gate for pallets, offering reliable mid-level resistance with a double-acting return stroke.
Is the Airtac SAI50 Standard Cylinder SAI50X220 the Right Cylinder?
Selecting this 50mm bore provides a noticeable thrust upgrade over the 40mm version, which offers 628 N at 0.5 MPa, without stepping up to the larger 63mm class. The 220mm stroke is ideal for applications requiring extended reach. Because this stroke exceeds 300mm, it does not strictly require external guides, but for any longer custom strokes, managing side load on the rod bearing becomes critical to prevent premature wear.
As a dimensionally interchangeable ISO 15552 cylinder, this model serves as a direct replacement for other profile cylinders matching the 50mm bore, 220mm stroke, and G1/4 port size. It utilizes adjustable air cushions at both ends to decelerate the piston. Note that it will not hold a load if air pressure is lost; for position holding, consider the SAIL variant with an air-released lock.
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.
