About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-40S
The AirTAC SAIJ80X130-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 90-130 mm, allowing you to dial back the 130 mm nominal stroke by up to 40 mm during machine commissioning. Delivering 2513 N of push force at 0.5 MPa, it handles robust actuation tasks.
This unit includes a carbon steel rod and a PT tapered port. Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves. The rear stopper acts as a travel end-limit, not a load lock, so live air is required to hold position.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-40S Is Used
Machine Setup Tuning
Fine-tune the 90-130 mm travel window at commissioning to dial in exact end positions without machining new hard stops.
Product Changeover
Quickly adapt the cylinder stroke on packaging lines when handling different carton sizes or product widths.
Variable End Stops
Use the rear screw to set precise retract limits on automated assembly stations requiring strict positional control.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-40S the Right Cylinder?
Choose this 80 mm bore when 50 mm (982 N push) is too weak but 100 mm (3927 N) is oversized. The 40 mm adjustment range is ideal for product changeovers where exact end-stops vary, eliminating the need to swap cylinders or add external stops. For position holding without air pressure, select a SAIL or BSAI model instead, as this adjuster is not a brake.
Because the stroke is 130 mm, side-load risks are moderate, but ensure the M20x1.5 rod thread is properly aligned. It uses the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, TCM2. For ISO 15552 replacement, match the 80 mm bore, 130 mm stroke, 40 mm adjust, PT port, and -S magnet.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80X130-40S FAQ
At 0.5 MPa operating pressure, it provides 2513 N of push force and 2268 N of pull force. At 0.9 MPa, the push force reaches 4523 N.
The rear adjuster screw lets you shorten the 130 mm nominal stroke by up to 40 mm, creating a 90-130 mm usable travel window. It acts as a mechanical stop and does not lock the load without live air.
