About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-100S
The AirTAC SAIJ100X220-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa and provides a usable travel window of 120 to 220 mm, letting you trim the nominal 220 mm stroke by up to 100 mm. This wide adjustment range is ideal for dialing in exact end positions during machine commissioning without swapping components.
Built for demanding environments, this variant uses a SUS304 stainless steel rod (code B) for superior corrosion resistance. It includes a magnet for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and the mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-100S Is Used
Product Changeover Tuning
Quickly adapt the 120-220 mm travel window for different product sizes on the same line without disassembling the cylinder or adding external mechanical stops.
Variable End-Stop Positioning
Dial in the exact retract end-position during machine commissioning using the rear adjuster screw to perfect the deceleration and final placement of heavy loads.
Heavy Assembly Pressing
Leverage the 3927N push force at 0.5 MPa for pressing and seating components, while relying on the SUS304 rod for corrosion resistance in industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-100S the Right Cylinder?
Choose this 100 mm bore when you need heavy thrust but require frequent product changeovers; its 100 mm adjustment window easily handles varying material lengths. If your application needs less force, stepping down to an 80 mm bore yields 2513N at 0.5 MPa. Because the stroke is 220 mm, ensure external guidance for heavy loads to prevent rod side-loading, as the 25 mm rod and M20x1.5 thread handle high forces but cannot support lateral loads alone.
The rear adjuster acts solely as a travel stop to set deceleration endpoints, not as a load lock. If the assembly must hold position without live air pressure, use a SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 220 mm stroke, 100 mm adjustment, PT tapered ports, SUS304 rod, and the -S magnet option.

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 SAIJ100 Adjustable Cylinder SAIJ100BX220-100S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 220 mm down to as little as 120 mm. This creates a 120-220 mm adjustable window for fine-tuning the end position at commissioning without changing the cylinder.
