This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X195S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI100 Standard Cylinder SI100X195S
The AirTAC SI100 Standard Cylinder SI100X195S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 195mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X195S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X195S
The AirTAC SI100X195S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 195mm stroke, delivering a push force of 3927 N at 0.5 MPa. AirTAC replaced this legacy unit with the SAI100X195S, a direct upgrade retaining the exact G1/2 port, M20x1.5 rod thread, and ISO 15552 mounting interface. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life.
This -S variant includes a piston magnet for legacy CS1-B/DS1-B switches, while the SAI replacement family utilizes current AirTAC sensors. The standard cylinder operates at 30-800 mm/s within a -20 to +70 C range, though a Viton H seal option raises the thermal limit to 150 C. Remember that a plain cylinder relies on adjustable air cushions only to decelerate the piston near stroke end; it cannot hold a load on air loss. For secure load holding, consider the SAIL air-released lock or BSAI clamp-lock variants that the original SI line lacked.

Where the Airtac SI100 Standard Cylinder SI100X195S Is Used
Heavy-Duty Pressing
Ideal for applying high clamping forces in automated assembly lines, utilizing the 3927 N push force at 0.5 MPa to seat bearings or form components securely.
Material Diversion
Provides robust actuation for heavy-duty conveyor sorting gates, using the 195mm stroke to push industrial packages cleanly off the main belt line.
Replacing the Airtac SI100 Standard Cylinder SI100X195S with the SAI100X195S
To replace the discontinued SI100X195S, order the SAI100X195S. Confirm the ISO 15552 mounting interface (such as LB foot or TC trunnion), the 100mm bore, 195mm stroke, G1/2 port, and the -S magnet requirement. The SAI family also adds SAIF (built-in 4M valve) and BSAI (clamp-lock) variants if your fixture needs integrated control or locking. When sizing, the 100mm bore yields 3927 N push at 0.5 MPa; dropping to an 80mm bore reduces push to 2513 N, while increasing to 125mm provides 6136 N. Because this is a double-acting cylinder, a plain SAI does not hold load without live air—the cushions only decelerate. For suspended loads, specify the SAIL lock variant or an external pilot check valve. With a 195mm stroke, side-load and rod-bending stresses are minimal, but always ensure proper guide alignment to prevent seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X195S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
