About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-50
The AirTAC SAIJ100X270-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 5497N of push force at 0.7 MPa. The integrated 50mm adjustment mechanism creates a usable travel window between 220mm and 270mm, enabling precise end-position tuning during commissioning without adding external stops.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. While the rear adjuster and variable air cushions decelerate the load at the travel end, this cylinder does not hold position without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-50 Is Used
Machine Changeover
Dial in the 220-270mm travel window during product size transitions to set new end positions without physically swapping the cylinder.
Commissioning Tuning
Fine-tune the final end-stop position at machine setup, compensating for mechanical tolerances using the rear 50mm adjustment screw.
Variable End Stops
Establish precise deceleration points for heavy 3927N push operations, leveraging the built-in air cushions and adjustable rear stopper.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-50 the Right Cylinder?
Choose this 100mm bore cylinder when a 63mm bore (1402N pull at 0.5 MPa) lacks the required force, or step down to an 80mm bore (2268N pull at 0.5 MPa) to save space if lower thrust is acceptable. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers, unlike a fixed-stroke SAI cylinder. Because the 270mm stroke exceeds 250mm, an external guide is recommended to manage side loads on the 25mm rod. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead. To match this exact configuration, specify bore 100, stroke 270, adjustment 50, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and no magnet.
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 SAIJ100BX270-50 FAQ
At 0.7 MPa it provides 5497N of push force and 3681N of pull force. The operational speed range is 30-800 mm/s.
The rear adjuster acts as a travel stop, allowing you to shorten the effective stroke from the nominal 270mm down to 220mm. It is a stop, not a lock, so it will not hold the load without live air pressure.
