About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-50S
The AirTAC SAIJ100X135-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927 N push force at 0.5 MPa and features a 50 mm adjustment range, creating an exact 85-135 mm usable travel window for precise end-position tuning. This cylinder includes a -S magnet for position detection and uses a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance.
The extruded aluminum barrel incorporates sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid supply connects via a PT G1/2 tapered port, and the rear adjuster functions purely as a mechanical stop to dial in the stroke during commissioning without requiring a cylinder swap.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-50S Is Used
Product Changeovers
Quickly dial the stroke from 135 mm down to 85 mm via the rear screw to accommodate varying carton sizes on a packaging line without swapping hardware.
End-Stop Calibration
Fine-tune the final retract position during machine commissioning to achieve exact clamping contact, utilizing the 50 mm adjustment range for perfect alignment.
Variable Diverter Stroke
Adjust the travel distance of a sorting pusher on the fly to handle different package depths while maintaining the high 3927 N push force required to move heavy items.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-50S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (2513 N push at 0.5 MPa) lacks thrust, but a 125 mm bore is physically too large. The 50 mm adjustment window is ideal for product changeovers on a packaging line, allowing operators to dial back the 135 mm nominal stroke down to 85 mm without adding external stops. For fixed travel without the need for end-position tuning, a standard SAI cylinder is sufficient.
When ordering a replacement, verify the 100 mm bore, 135 mm stroke, 50 mm adjustment, PT G1/2 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Note that the rear adjuster and air cushions only decelerate the load; they do not hold position without live air, so consider an SAIL lock or BSAI clamp-lock for fail-safe load 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 SAIJ100 Adjustable Cylinder SAIJ100AX135-50S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At a maximum 1.0 MPa, it can deliver up to 801 kgf.
The rear mechanical stopper allows you to trim the effective travel back by up to 50 mm from the nominal 135 mm stroke, providing an adjustable operating window of 85 to 135 mm. It acts as a travel stop and does not lock the load without continuous air pressure.
