About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-50S
The AirTAC SAIJ100X195-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 145 to 195 mm. Delivering a robust 3927 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod (option B) and a PT tapered port thread. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches.
The 50 mm adjustment mechanism allows operators to fine-tune the retract end-position during commissioning or product changeovers without swapping out the entire cylinder or adding external stops. It utilizes a variable air cushion at both ends to manage deceleration, but the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-50S Is Used
Variable End-Stop Tuning
Dial in the 145-195 mm travel window during machine commissioning to perfectly strike a workpiece without machining custom spacers.
Product Size Changeover
Quickly adapt the retract position on a packaging line when switching between different product sizes, using the 50 mm adjustment range to reset the end-stop.
Assembly Press Setup
Leverage the 3927 N push force at 0.5 MPa for light pressing operations while fine-tuning the exact bottoming position to prevent over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-50S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore falls short on thrust, providing 2513 N push at 0.5 MPa, or when stepping down from a 125 mm bore that delivers 6136 N. The adjustable stroke is ideal for applications requiring variable end-stops or precise machine setup, whereas a fixed-stroke SAI cylinder is better suited for rigid, unchanging travel requirements. When matching an ISO 15552 replacement, verify the 100 mm bore, 195 mm stroke, 50 mm adjustment range, PT port thread, and the -S magnet option. Because the 25 mm rod and M20x1.5 rod thread carry substantial side loads, ensure proper external guiding is used for this 195 mm stroke.
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 SAIJ100BX195-50S 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 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you shorten the nominal 195 mm stroke by up to 50 mm, creating a usable travel window of 145 to 195 mm. The adjuster acts as a mechanical stop to fine-tune the end position and does not function as a lock to hold the load without air pressure.
