Airtac SAIJ80 Adjustable Cylinder SAIJ80BX850-10
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80BX850-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 850mm 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 SAIJ80BX850-10
The AirTAC SAIJ80X850-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 840-850mm usable travel window. It delivers a robust 2513N pull force at 0.5 MPa and uses a PT tapered G3/8 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance. The rear adjuster acts purely as a mechanical stop for end-position tuning during commissioning; it does not hold the load without live air. For load-holding requirements, explore the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX850-10 Is Used
Product Changeover
Dial in the 840-850mm retract stop during format changes on a packaging line without swapping the entire cylinder.
Machine Setup
Fine-tune the exact end-of-stroke position during equipment commissioning to avoid mechanical interference.
Long-Stroke Assembly
Execute long-travel pressing or lifting tasks where a 2513N pull force and precise final positioning are required.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX850-10 the Right Cylinder?
Choose this 80mm bore cylinder when you need the 2513N pull force class but require precise end-position tuning without adding external stops. If your application needs less force, the 50mm bore offers 825N pull at 0.5 MPa. This SAIJ model provides a 10mm adjustment window for product changeovers, unlike a fixed-stroke SAI cylinder.
Because the 850mm stroke is long, the 25mm SUS304 rod and M20x1.5 thread carry substantial side loads, but an external guide rail is still required to prevent binding. This ISO 15552 cylinder uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 SAIJ80BX850-10 FAQ
The rear adjusting screw allows you to shorten the effective stroke by up to 10mm, providing a usable travel window of 840-850mm. It acts as a mechanical stop for fine-tuning end positions and is not a lock.
At 0.5 MPa operating pressure, it provides 2513N of pull force and 3518N of push force. The maximum push force is 4523N at 0.7 MPa.
