About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX85-10
The AirTAC SAIJ100X85-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the end-of-travel position during commissioning. It provides a usable travel window of 75-85 mm by allowing up to 10 mm of adjustment from the nominal 85 mm stroke, eliminating the need for external stops. Delivering 3927 N of push force at 0.5 MPa, it handles substantial loads with precision.
This specific SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance, and features PT tapered port threads. It supports speeds of 30-800 mm/s and includes variable air cushions at both ends to manage deceleration. For position sensing, you can add a magnet (-S) to use with CMSE reed or DMSE solid-state sensors in the dual-side barrel grooves.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX85-10 Is Used
Product Changeover
Dial in the 75-85 mm travel window during packaging line format changes to accommodate different carton sizes without swapping hardware.
Machine Setup
Fine-tune the retract end-position at commissioning to set exact pressing depths, using the rear stopper instead of adding external mechanical stops.
High-Force Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy jigs into place, relying on the SUS304 rod for durability in harsh environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX85-10 the Right Cylinder?
Choose this 100 mm bore cylinder when your application requires high thrust forces up to 3927 N at 0.5 MPa (or 5497 N at 0.7 MPa) alongside exact end-position tuning. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa, whereas a larger 125 mm bore provides 6136 N. The adjustable rear stopper is ideal for machine setups requiring variable end stops or product-size changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 100 mm bore, 85 mm stroke, 10 mm adjustment, PT ports, and the SUS304 (B) rod material. Note that the rear adjuster and air cushions act only as travel stops and deceleration devices; they do not hold the load without live air. For load-holding requirements without continuous pressure, consider the SAIL locking cylinder or BSAI clamp-lock type. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100BX85-10 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 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the nominal 85 mm stroke by up to 10 mm, creating a usable travel window of 75-85 mm. It acts as a mechanical stop to fine-tune the end position and requires live air to hold the load.
