About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X850-10
The AirTAC SAIJ100X850-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 840 to 850 mm, allowing you to trim the effective stroke by up to 10 mm. Delivering 7068 N of push force at 0.9 MPa, it is built with a carbon steel piston rod and a G1/2 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This adjustable model lets you fine-tune the retract end-position during commissioning without swapping the cylinder or adding external stops. The rear adjuster acts as a travel stop for deceleration, not a lock, so it will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X850-10 Is Used
Machine Changeover
Dial in the 10 mm stroke adjustment to perfectly match new product dimensions during line changeovers without replacing the actuator.
Long-Stroke Diverting
Drive large diverters or gates across an 840-850 mm travel window, using the rear stop to fine-tune the resting position.
Heavy Load Positioning
Leverage the 7068 N push force to shift heavy pallets or fixtures, using the adjustable end-stop to compensate for mechanical wear over time.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X850-10 the Right Cylinder?
Choose this 100 mm bore cylinder when an application demands high thrust (7068 N at 0.9 MPa) alongside precise end-stop tuning. If your setup requires less force, stepping down to an 80 mm bore yields 4523 N, while a 125 mm bore provides 11045 N for heavier loads. The 10 mm adjustment range is ideal for dialing in exact positioning during machine changeover, whereas a fixed-stroke SAI cylinder is sufficient when no end-trim is needed.
Because the 850 mm stroke is relatively long, ensure adequate support to prevent rod sag and side-loading; an external guide is recommended for unsupported spans. This cylinder uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It features PT tapered ports and no standard magnet; add the -S suffix if CMSE reed or DMSE solid-state sensors are required.

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 SAIJ100X850-10 FAQ
