This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X150TC, 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.
Airtac SU32~50 Standard Cylinder SU50X150TC
The AirTAC SU32~50 Standard Cylinder SU50X150TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X150TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X150TC
The AirTAC SU50X150TC is a discontinued double-acting profile-type cylinder featuring a 50mm bore, 150mm stroke, and a TC mounting interface. It delivers 982 N of push force at 0.5 MPa through a 1/4" port. Because this SU series is end-of-life, AirTAC specifies the SAU50X150TC as the direct replacement, matching the original bore, stroke, output force, port size, and SC-series mounting accessories.
Buyers gain two key upgrades in the SAU series: current CMSG/DMSG/EMSG sensors replace the legacy CS1-B/DS1-B switches, and the new SAUF variant offers a built-in 4M solenoid valve the SU line lacked. Note that this specific SKU lacks a magnet, so it cannot accept a magnetic piston switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X150TC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X150TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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.
Where the Airtac SU32~50 Standard Cylinder SU50X150TC Is Used
Package Diverting
Actuates TC-mounted diverting arms on packaging lines, utilizing the 982 N push force at 0.5 MPa to push cartons reliably without overshooting.
Clamp Actuation
Drives mid-force clamping fixtures on machining cells, taking advantage of the compact profile body to save space in tight tooling layouts.
Replacing the Airtac SU32~50 Standard Cylinder SU50X150TC with the SAU50X150TC
To replace the discontinued SU50X150TC, order the SAU50X150TC direct equivalent, confirming the 50mm bore, 150mm stroke, 1/4" port, M16x1.5 rod thread, and TC mounting accessory. Since this is a non-magnet SKU, it cannot support sensing; if detection is needed, an SAU model with an -S suffix must be specified, which then requires the newer CMSG/DMSG/EMSG switch family instead of the old CS1-B/DS1-B. When sizing, check both directions: dropping to a 40mm bore reduces push force to 628 N at 0.5 MPa, while stepping up to a 63mm bore increases it to 1559 N. At 150mm stroke, side-load risks are low, but always guide the load to prevent rod bending. A plain double-acting cylinder drifts on air loss—the cushion only decelerates near stroke end—so install an external rod lock or pilot-operated check valve for held loads. For automated self-switching, consider the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X150TC
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU32~50 Standard Cylinder SU50X150TC FAQ
Yes, the SU50X150TC is discontinued. The direct replacement is the AirTAC SAU50X150TC. It shares the identical 50mm bore, 150mm stroke, 1/4" port, and TC mounting, so it bolts right into the same application.
The 50mm bore uses a 1/4" port with an M16x1.5 rod thread. It generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical maximum of 200 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot accept magnetic switches.
