About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX275-30
The AirTAC SAIJ200X275-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits an effective travel window of 245 to 275 mm. Built with a SUS304 stainless steel rod and PT tapered G3/4 ports, it generates a substantial 15708 N of push thrust at 0.5 MPa and safely operates at speeds of 30-500 mm/s.
Because the external stopper acts solely on the retract end to fine-tune position without requiring cylinder replacement, it is ideal for heavy product changeovers. The extruded aluminum barrel incorporates sensor grooves on both sides for tracking, though this specific configuration omits the magnet, meaning CMSE reed or DMSE electronic sensors cannot be used without modification.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX275-30 Is Used
Heavy Pressing Alignment
Fine-tune the 245-275 mm retract distance during machine commissioning to perfectly seat heavy components without swapping out the entire ISO 15552 cylinder.
Product Size Changeover
Adapt automated heavy-assembly lines to varying product dimensions by turning the rear stopper to shift the end-of-stroke position on the fly.
Variable End-Stop Calibration
Dial in the exact clamping or ejection point during setup, using the 30 mm adjustment range to compensate for mechanical wear or tooling variations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX275-30 the Right Cylinder?
Selecting this 200 mm bore over the neighbouring 160 mm option steps the 0.5 MPa push force up from 10053 N to 15708 N, providing the necessary thrust for heavy pressing or lifting. The adjustable stroke is chosen over a fixed SAI model when a machine setup requires a variable end-stop to dial in exact retract distances during commissioning.
It is critical to note that the rear adjuster functions only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. Mounting options are restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 275 mm stroke exceeds the 300 mm threshold requiring external guidance, you should support heavy lateral loads with an external guide to protect the 40 mm rod from excessive side-load wear.
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 SAIJ200 Adjustable Cylinder SAIJ200BX275-30 FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can deliver a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke back by up to 30 mm, creating a usable travel window of 245 to 275 mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
