About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX35-30S
The AirTAC SAIJ200X35-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a massive 15708N push force at 0.5 MPa and features a 35mm nominal stroke that can be fine-tuned down by 30mm, yielding a precise 5-35mm usable travel window. This built-in adjustability allows operators to dial in exact end positions during commissioning without adding external stops.
This SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It operates at 30-500mm/s and uses a PT G3/4 port. The rear adjuster functions strictly as a travel stop for end-position tuning, not a lock, meaning it will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX35-30S Is Used
Short-Stroke Pressing
Applies up to 3204kgf of clamping force in compact spaces, using the 5-35mm travel window to precisely tune the pressing depth without changing fixtures.
Product Changeover
Enables rapid line changeovers by allowing operators to simply dial back the rear stopper by up to 30mm to accommodate varying part sizes.
Heavy Duty End-Stops
Replaces fixed stops in heavy automation by providing an adjustable mechanical stopper, ensuring exact retraction end positions during machine setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX35-30S the Right Cylinder?
Choose this 200mm bore cylinder when an application demands extreme thrust within a very short, adjustable travel window. If 15708N at 0.5MPa is excessive, stepping down to the 160mm bore yields 10053N of push force. Select the SAIJ adjustable design over a fixed-stroke SAI when machine setups require variable end-stops or frequent product changeovers. To match this exact replacement, specify: 200mm bore, 35mm stroke, 30mm adjustment, PT G3/4 port, SUS304 rod, and a magnet for CMSE / DMSE sensors.
Although the 35mm stroke is short, the 40mm rod diameter provides excellent rigidity and side-load capacity. The standard SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Note that holding a load securely without continuous air pressure requires an external rod lock or a pilot-operated check valve, as the air cushion and rear stopper only manage deceleration.

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 SAIJ200 Adjustable Cylinder SAIJ200BX35-30S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 3204kgf.
The rear adjuster acts as a mechanical stop, allowing you to trim the 35mm nominal stroke down by up to 30mm. This creates a usable travel window of 5-35mm for fine-tuning end positions at commissioning without swapping the cylinder.
