Airtac SAIJ100 Adjustable Cylinder SAIJ100X60-20
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X60-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 60mm stroke, G1/2 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 SAIJ100 Adjustable Cylinder SAIJ100X60-20
The AirTAC SAIJ100X60-20 is a double-acting single-rod profile cylinder dimensionally interchangeable per ISO 15552, featuring a built-in rear stroke adjuster. It provides a usable travel window of 40 to 60 mm, letting you dial back the 60 mm nominal stroke by up to 20 mm during commissioning. This 100 mm bore generates 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it suited for heavy-duty positioning. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches if a magnet is specified later. It uses a G1/2 port and M20x1.5 rod thread, handling speeds of 30-800 mm/s with variable air cushions at both ends.
The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position without swapping the cylinder or adding external stops. It is not a lock; a plain SAIJ does not hold loads without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The standard carbon steel rod handles robust side loads, while seal options like Viton H are available for high-temperature environments.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X60-20 Is Used
Machine Setup Changeovers
Dial in the exact end position from 40 to 60 mm during product-size changeovers without physically swapping the cylinder or bolting on external stops.
Variable End-Stop Positioning
Fine-tune the retract stroke on automated assemblies where the exact end position needs on-the-fly adjustment to accommodate varying material thicknesses.
Heavy-Duty Clamping
Leverage the 3927 N push force at 0.5 MPa to secure heavy workpieces, using the rear adjuster to precisely set the clamp's retracted clearance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X60-20 the Right Cylinder?
Choose this 100 mm bore when you need substantial force—3927 N at 0.5 MPa—and the ability to fine-tune a short 40-60 mm travel window. If your application requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The adjustable-stroke design is ideal for machine setups requiring variable end stops or product-size changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot match.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 60 mm stroke, 20 mm adjustment, G1/2 PT port, and required mounting bracket. Because the stroke is under 300 mm, side-load concerns are minimal, but long unsupported loads still require an external guide. Ensure your setup does not rely on the rear adjuster or air cushions for load holding, as they only decelerate and set travel ends. For true load-holding without live air, use a SAIL or BSAI cylinder.
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 SAIJ100 Adjustable Cylinder SAIJ100X60-20 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 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 60 mm nominal stroke by up to 20 mm, creating a usable travel window of 40 to 60 mm. It only sets the end position and does not hold the load without live air.
