This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X130, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.

The AirTAC Airtac SU32~50 Standard Cylinder SU40X130 is a double-acting profile-type standard cylinder with a Ø40mm bore and 130mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X130, which matches its bore, stroke, force and mounting.
The AirTAC SU40X130 is a discontinued double-acting profile-type cylinder with a 40 mm bore and 130 mm stroke. Delivering 628 N push force at 0.5 MPa, it features an extruded aluminum barrel and adjustable air cushions at both ends, making it more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this EOL unit with the SAU40X130, a direct replacement retaining the exact 1/4" port, M12x1.25 rod thread, and SC-series mounting.
Upgrading to the SAU40X130 preserves the 628 N push and 528 N pull forces at 0.5 MPa. Note this non-magnetic SKU cannot accept a sensor, and while the SAU line adds a valve-integrated SAUF option, a plain cylinder will not hold a load without air—use an external rod lock for vertical safety.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X130 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X130 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Actuates diverting arms on 40 mm belt conveyors, providing 628 N push at 0.5 MPa to redirect cartons efficiently without overshooting.
Functions as a pneumatic stop gate in low-profile roller lanes, using its 21 mm adjustable cushions to halt 32 kg workloads smoothly.
Drives mid-force clamping fixtures on CNC machining cells, delivering a safe 377 N working load within a compact extruded body.
To replace the SU40X130, order the SAU40X130 direct equivalent, confirming the 40 mm bore, 130 mm stroke, 1/4" port (PT/G/NPT), and SC-series mounting (LB/FA/FB/CA/CB). This non-magnetic SKU cannot take a sensor; if detection is needed, specify an -S magnet on the SAU, which requires current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing both ways: a 32 mm bore yields 402 N push at 0.5 MPa, while a 50 mm bore yields 982 N. The 130 mm stroke is under the 1200 mm standard max, but for any stroke over 300 mm, add a guide to prevent rod bending from side loads. The SAU also offers a SAUF variant with a built-in 4M solenoid valve. Finally, the air cushion only decelerates; use a pilot-operated check valve or rod lock to hold loads safely.
Replacement checklist
Yes, the SU40X130 is discontinued. The direct replacement is the AirTAC SAU40X130. It matches the 40 mm bore, 130 mm stroke, 1/4" port, 628 N force, and SC-series mounting, fitting the same application.
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa it pushes 879 N, and the theoretical max is 128 kgf at 1.0 MPa. This non-magnetic SKU cannot accept a sensor; if sensing is needed, order the SAU with an -S magnet (which uses CMSG/DMSG/EMSG switches).
Send us the quantity and destination. We confirm price, stock and lead time on the SAU40X130 replacement — usually within 7-8 hours.
