About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-75
The AirTAC SAIJ100X195-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the end-of-travel position. With a 195 mm nominal stroke and a 75 mm adjustment range, this model provides a usable travel window of 120 to 195 mm. It belongs to the 100 mm bore class, generating 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it well-suited for heavier actuation tasks.
This specific SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. The rear adjuster functions strictly as a mechanical stop to set the retraction end position; it does not hold the load without live air pressure. For load-holding without continuous pneumatic pressure, an external rod lock or a related SAIL pneumatic-lock cylinder is required.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-75 Is Used
Machine Changeover
Dial in the exact retraction distance from 120 to 195 mm during product size changeovers without replacing the cylinder or adding external stopper blocks.
Assembly Line Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets, using the rear adjuster to fine-tune the resting position for precise tooling alignment.
Press Fit Tuning
Set the exact travel end for pressing operations, allowing the mechanical stop to define the final position while relying on live air for the driving force.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX195-75 the Right Cylinder?
Selecting this 100 mm bore adjustable cylinder is ideal when an application requires precise end-position tuning during commissioning or frequent product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your process demands less force, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa while saving space. Conversely, heavier loads may require the 125 mm bore, which provides 6136 N of push force.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 195 mm nominal stroke, 75 mm adjustment range, PT port thread, and standard mounting interface. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 195 mm stroke is relatively long, ensure adequate support to prevent rod sag or side-loading, using an external guide if necessary. The standard speed range is 30-800 mm/s.

- ✓ 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 SAIJ100BX195-75 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop that trims the effective travel. For the SAIJ100X195-75, you can shorten the 195 mm nominal stroke by up to 75 mm, creating a usable travel window of 120 to 195 mm. It sets the end position but does not lock the load without air pressure.
