About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX35-30S
The AirTAC SAIJ50X35-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 5 to 35 mm, allowing you to dial back the 35 mm nominal stroke by up to 30 mm during machine commissioning. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, fitting medium-duty tasks perfectly.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port. The extruded aluminum barrel features sensor grooves on both sides, and the integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to set end positions and relies on the built-in air cushions for deceleration, so it does not hold loads without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX35-30S Is Used
Position Calibration
Dial in the exact 5 to 35 mm travel distance during machine setup without swapping out physical hardware.
Product Changeover
Quickly adjust the retract end-stop on packaging lines when handling different package sizes.
Lab Automation
Leverage the SUS304 rod and precise stroke tuning for repeatable testing motions in clean environments.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX35-30S the Right Cylinder?
Select this 50 mm bore adjustable cylinder when you need variable end-stops for frequent product changeovers instead of a fixed-stroke SAI unit. If your application requires less force, stepping down to a 40 mm bore yields 628 N of push force at 0.5 MPa; stepping up to a 63 mm bore provides 1559 N. Because the stroke is 35 mm, side-load risks are minimal, but always guide the load for stability.
For exact ISO 15552 dimensional interchangeability, match the 50 mm bore, 35 mm nominal stroke, 30 mm adjustment range, PT ports, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting options. If your process demands true load-holding without continuous air pressure, this cylinder will not suffice—consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
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 SAIJ50 Adjustable Cylinder SAIJ50BX35-30S FAQ
At a 0.5 MPa operating pressure, this 50 mm bore cylinder provides a push force of 982 N and a pull force of 825 N. At the maximum 1.0 MPa pressure, it delivers up to 200 kgf of push force.
The rear adjuster screw lets you shorten the 35 mm nominal stroke by up to 30 mm, creating a usable travel window of 5 to 35 mm. It functions as a mechanical stop for end-position tuning and is not a locking mechanism.
