This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX195, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI160 Standard Cylinder SI160BX195
The AirTAC SI160 Standard Cylinder SI160BX195 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 195mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX195, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX195
The AirTAC SI160BX195 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 195 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160BX195, matching the exact bore, stroke, force, port and mounting interface.
This SKU features a SUS304 stainless piston rod (B suffix) and lacks a magnet, so it cannot accept legacy CS1-B/DS1-B sensors. The SAI upgrade adds a two Y-shaped one-way piston seal for low start-up pressure.

Where the Airtac SI160 Standard Cylinder SI160BX195 Is Used
Heavy Press Clamping
Ideal for applying 10053 N of clamping force at 0.5 MPa to secure large steel fabrications during welding or machining operations.
Stamping Press Feed
Drives heavy-duty feeding mechanisms in stamping lines, utilizing the 50 mm adjustable air cushions to decelerate massive payloads smoothly.
Replacing the Airtac SI160 Standard Cylinder SI160BX195 with the SAI160BX195
To replace this SI160BX195, order the SAI160BX195 keeping the identical ISO 15552 mounting interface, 160 mm bore, 195 mm stroke, G3/4 port, and SUS304 rod. Because this SKU lacks a magnet (-S), it cannot support position sensing; if sensing is needed, specify an SAI160BX195S. For loads requiring holding on air loss, a plain cylinder drifts—use an external pilot check valve, rod lock, or the SAIL/BSAI lock variants. At 195 mm stroke, side-load risks are low, but always guide the load to prevent rod bending. Neighbouring bores: 125 mm yields 6136 N push @0.5 MPa, while 200 mm yields 15708 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX195
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160BX195 FAQ
Yes, the AirTAC SI160BX195 is discontinued. The direct replacement is the SAI160BX195. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 195 mm stroke, output force, G3/4 port, and mounting accessories.
This double-acting cylinder uses a G3/4 air port. At 0.5 MPa it provides 10053 N push and 9425 N pull force. At 0.7 MPa push is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical maximum force is 2050 kgf at 1.0 MPa.
