About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-30S
The AirTAC SAIJ160X950-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that fine-tunes the retract end position. With a 950 mm nominal stroke and a 30 mm adjustment range, it provides a usable travel window of 920-950 mm for exact commissioning without adding external stops. It delivers substantial thrust, pushing 14074 N at 0.7 MPa.
This variant uses a SUS304 stainless steel rod for corrosion resistance and includes a magnet for AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel carries sensor grooves on both sides. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-30S Is Used
Variable End-Stop Machining
Dial in the 920-950 mm travel window during setup to trim different material lengths without swapping cylinders or bolting on external stoppers.
Product Size Changeover
Quickly reposition the retract end position on a packaging line when product dimensions change, using the 30 mm rear adjuster for fine-tuning.
Long-Stroke Assembly Press
Leverage the 14074 N push force at 0.7 MPa to seat large components, relying on the 50 mm air cushion to decelerate the heavy tooling at the end of travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-30S the Right Cylinder?
Choose this 160 mm bore when 10053 N of push force at 0.5 MPa is insufficient but stepping up to a 200 mm bore (15708 N at 0.5 MPa) is unnecessary. The adjustable stroke is ideal for machine changeovers where exact end-of-trim varies by product size, unlike a fixed SAI cylinder. Because the 950 mm stroke is long, the M36x2 rod and 50 mm cushion cannot prevent rod sag alone; an external guide is required to manage side loads.
For ISO 15552 replacement matching, verify the 160 mm bore, 950 mm stroke, 30 mm adjustment, PT tapered G3/4 port, SUS304 rod, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. For load-holding without live air, select SAIL or BSAI instead.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX950-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can reach up to 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the 950 mm nominal stroke by up to 30 mm, giving an effective travel range of 920 to 950 mm. It does not lock the load without live air pressure.
