About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX30-30
The AirTAC SAIJ160X30-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. It features a robust 160mm bore and a nominal 30mm stroke, paired with a rear-mounted adjusting screw that allows you to trim the effective travel back by up to 30mm. This yields a highly versatile 0-30mm usable travel window, enabling exact commissioning adjustments without swapping out the physical cylinder. At 0.5 MPa operating pressure, it delivers 10053N of pull force, scaling up to 18095N at 0.9 MPa for demanding industrial workloads.
Built with a SUS304 stainless steel rod and PT tapered port threads, this unit resists corrosion while maintaining a tight pneumatic seal. The extruded aluminum barrel includes sensor grooves on both sides for straightforward CMSE or DMSE sensor integration. It is important to note that the rear adjuster acts purely as a mechanical stop to decelerate and set the travel end; it does not hold the load without live air pressure. For load-holding requirements without continuous air, an external rod lock or related types like SAIL or BSAI should be considered.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX30-30 Is Used
Press Stroke Calibration
Dial in the exact 0-30mm travel window during machine commissioning to perfectly seat heavy bearings or bushings without over-traveling and damaging the workpiece.
Product Changeover
Quickly adjust the rear stopper on automated assembly lines when switching between product variants of slightly different heights, eliminating the need to physically swap cylinders.
Heavy Clamping Fixtures
Leverage the 10053N pull force at 0.5 MPa to secure heavy steel components for machining, using the adjustable stroke to compensate for varying raw material thicknesses.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX30-30 the Right Cylinder?
Selecting the SAIJ160X30-30 is ideal when your machine setup requires variable end-stops on a short-stroke, high-force actuator. Instead of fabricating custom external stops or stocking multiple fixed-stroke SAI cylinders for product changeovers, the rear screw mechanism allows you to dial in the exact 0-30mm travel window on the fly. When specifying this model, confirm the 160mm bore, 30mm nominal stroke, 30mm adjustment range, PT port threads, SUS304 rod material, and the absence of a magnet. Because the nominal stroke is only 30mm, side-load risks are minimal, but the heavy 40mm rod diameter still dictates that loads should be guided to prevent binding.
If you need to step the bore down to reduce physical size and thrust, a 125mm bore offers 6136N push force at 0.5 MPa. Conversely, moving up to a 200mm bore yields 15708N push at 0.5 MPa. This SAIJ model utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 standards, ensuring it drops seamlessly into existing fixture layouts without proprietary footprint constraints.

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 SAIJ160BX30-30 FAQ
At an operating pressure of 0.5 MPa, the SAIJ160X30-30 generates 10053N of pull force and 10053N of push force. If you increase the pressure to 0.9 MPa, the push force scales up to 18095N, making it suitable for heavy-duty clamping and pressing.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 30mm. Since the nominal stroke is 30mm, this provides a usable travel window of 0-30mm, letting you fine-tune the exact end position at commissioning without changing the cylinder.
