About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-30S
The AirTAC SAIJ160X190-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 18095N at 0.9 MPa, making it suitable for heavy-duty operations. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches.
This model features a 190 mm nominal stroke that can be fine-tuned down by up to 30 mm, creating a precise 160-190 mm usable travel window. The carbon steel rod with an M36x2 thread provides a robust interface for high side-load resilience. It uses a PT tapered port and includes adjustable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-30S Is Used
Heavy Press Tuning
Dial in the exact 160-190 mm end position during machine setup to accommodate material thickness variations without changing the cylinder.
Product Changeover
Quickly adjust the stroke stop on a packaging line to handle different pallet or product sizes on the fly.
Heavy Load Shifting
Leverage the 18095N push force to move massive fixtures while relying on the adjustable air cushion to soften the impact.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-30S the Right Cylinder?
Select this 160 mm bore when you need extreme force that smaller bores cannot provide, such as the 125 mm bore which yields 11045N push at 0.9 MPa. The adjustable 160-190 mm travel window is ideal for applications requiring exact end-position tuning during commissioning or product changeover, eliminating the need to swap cylinders or add external stops. Because the stroke is 190 mm, ensure adequate external guiding if the load is heavy or unbalanced.
This SAIJ configuration includes a PT port, carbon steel rod, and a -S magnet. It is dimensionally interchangeable per ISO 15552. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC 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 SAIJ160 Adjustable Cylinder SAIJ160X190-30S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095N and a pull force of 9425N. It can deliver a maximum force of 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 190 mm nominal stroke by up to 30 mm, providing a usable travel window of 160-190 mm. It only sets the end position and does not lock the load without continuous air pressure.
