This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X860STC, 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 SU50X860STC
The AirTAC SU32~50 Standard Cylinder SU50X860STC is a double-acting profile-type standard cylinder with a Ø50mm bore and 860mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X860STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X860STC
The AirTAC SU50X860STC is a discontinued double-acting profile-type cylinder with a 50mm bore and 860mm stroke. It delivers 982 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced this legacy unit with the SAU50X860STC, a direct alternative retaining the exact bore, stroke, output force, and SC-series TC mounting interface.
Because this SKU includes the -S magnet, it originally used CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X860STC 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 SAU50X860STC 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 SU50X860STC Is Used
Long-Stroke Diversion
Pushes packages across a transfer line using the 860mm travel, relying on the 982 N push force at 0.5 MPa to overcome friction.
Actuated Guard Gate
Cycles a large machine safety door over a wide span, utilizing the TC mount and adjustable end cushions for smooth deceleration.
Replacing the Airtac SU32~50 Standard Cylinder SU50X860STC with the SAU50X860STC
To replace this SU50X860STC with the SAU50X860STC, verify the 50mm bore, 860mm stroke, 1/4" port, M16x1.5 rod thread, and TC mounting. If you need less force, a 40mm bore gives 628 N push at 0.5 MPa; if you need more, a 63mm bore yields 1559 N. The -S magnet means your legacy CS1-B/DS1-B switches will not fit the SAU groove—you must upgrade to CMSG/DMSG/EMSG sensors. Note that a plain cylinder drifts without live air (the 21mm cushions only decelerate), so fit an external rod lock or pilot-operated check valve for held loads. Finally, at 860mm, this long stroke risks rod bending under side loads—always use an external guide to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAU50X860STC
- ✓ 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 SU50X860STC FAQ
Yes, the SU50X860STC is discontinued. The direct replacement is the AirTAC SAU50X860STC. It matches the 50mm bore, 860mm stroke, 1/4" port, 982 N force, and TC mounting. You simply order the SAU equivalent.
The 50mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Because this model has the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
