Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-100S
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-100S
The AirTAC SAIJ80X130-100-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you dial the effective travel back by up to 100 mm. This creates a wide 30-130 mm usable positioning window on a 130 mm nominal stroke, ideal for machines that require frequent product-size changeovers. The 80 mm bore delivers 2513 N of pull force at 0.5 MPa, giving you robust thrust for mid-weight handling.
This unit includes a standard magnet for CMSE reed and DMSE electronic sensors, fitting directly into the extruded aluminum barrel grooves on both sides. It uses a PT tapered port and a 25 mm carbon steel rod with an M20x1.5 thread. The generous 36 mm air cushion at both ends manages end-of-stroke deceleration, but remember the adjuster is a travel stop, not a lock; it will not hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-100S Is Used
Variable End-Stop Setup
Dial in the exact retract position between 30 and 130 mm during machine commissioning without physically replacing the cylinder or bolting on external mechanical stops.
Product Size Changeover
Quickly adapt a packaging line to different carton heights by turning the rear adjuster, shifting the end-of-stroke position to match the new product dimensions.
Mid-Weight Forming
Leverage the 2513 N pull force at 0.5 MPa for pressing or locating medium-weight assemblies, using the 100 mm adjustment window to fine-tune the contact depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-100S the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (825 N pull at 0.5 MPa) is too weak, but you want to avoid the larger footprint and air consumption of a 100 mm option. The massive 100 mm adjustment range is perfect for commissioning setups where the exact end position varies wildly between product runs, saving you from swapping fixed-stroke SAI cylinders or adding external stops. To replace an ISO 15552 cylinder, match the 80 mm bore, 130 mm stroke, PT port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the 130 mm stroke is relatively short, side-load stress is minimal, though the 25 mm rod and M20x1.5 thread handle standard deflection well. If your process requires true load-holding without continuous air pressure, this adjustable stop is insufficient; you should look at the SAIL or BSAI locking cylinders instead.
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 SAIJ80 Adjustable Cylinder SAIJ80X130-100S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of pull force and 3518 N of push force. At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that shortens the 130 mm nominal stroke by up to 100 mm, giving a usable travel window of 30 to 130 mm. It sets the end position but does not lock the load without live air pressure.
