About the Airtac SAIJ125 Adjustable Cylinder SAIJ125BX95-10S
The AirTAC SAIJ125X95-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 85-95 mm usable travel window from its 95 mm nominal stroke. Delivering 8590 N of push force at 0.7 MPa, it handles heavy positioning without needing custom stops. The integrated magnet supports CMSE reed and DMSE electronic sensors for exact end-of-travel detection.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered ports. The extruded aluminum barrel houses variable air cushions at both ends to manage kinetic energy, while the rear screw acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125BX95-10S Is Used
Product Changeover
Dial in the 85-95 mm travel window during packaging line format changes to accommodate different carton sizes without replacing hardware.
Press Positioning
Leverage the 8590 N thrust at 0.7 MPa to seat heavy components, using the rear stopper to precisely set the final pressing depth.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning using the 10 mm adjuster, ensuring precise mechanical alignment before locking down.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125BX95-10S the Right Cylinder?
Choose this 125 mm bore when a 100 mm bore falls short on power, as stepping up from 100 mm increases push force at 0.7 MPa from 5497 N to 8590 N. The 10 mm adjustment range is ideal for fine-tuning end positions during machine commissioning or product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. For strokes of 95 mm, side-load is minimal, but always guide the load on longer unsupported travels.
To replace an ISO 15552 cylinder, match the 125 mm bore, 95 mm stroke, 10 mm adjuster, PT ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster is a stop, not a lock; for load-holding without live air, select the SAIL or BSAI series.
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 SAIJ125 Adjustable Cylinder SAIJ125BX95-10S FAQ
At 0.7 MPa operating pressure, this 125 mm bore cylinder provides 8590 N of push force and 5734 N of pull force. It can reach a maximum push force of 11045 N at 0.9 MPa.
The rear adjuster allows you to shorten the 95 mm nominal stroke by up to 10 mm, creating an 85-95 mm usable travel window. This stopper only sets the end position and decelerates the load; it does not hold the load without continuous air pressure.
