This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the drop-in replacement SAU50X910, 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 SU50X910
The AirTAC Airtac SU32~50 Standard Cylinder SU50X910 is a double-acting profile-type standard cylinder with a Ø50mm bore and 910mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAU50X910, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X910
The AirTAC SU50X910 is a discontinued double-acting profile-type cylinder with a 50mm bore and 910mm stroke. It delivers 982 N push and 825 N pull at 0.5 MPa via a 1/4" port. AirTAC replaced this legacy unit with the SAU50X910, a true drop-in upgrade retaining the exact bore, stroke, output force, port size and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors (replacing the old CS1-B/DS1-B) and adds an optional SAUF built-in 4M valve. For sizing, the safe working load is roughly 589 N (60% of the 982 N push), equating to a 50 kg vertical lift with a 2:1 margin. This extruded aluminium body is more compact than an ISO 15552 equivalent. Note: this no-magnet SKU cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X910 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 SAU50X910 produces the same force from the same bore — a true drop-in on output. 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 SU50X910 Is Used
Long-Stroke Diversion
Pushes packages across a 900mm conveyor belt lane, utilising the 982 N push force at 0.5 MPa to overcome guide friction.
Vertical Lift Gate
Raises a 50 kg access panel with a 2:1 safety margin, requiring an external guide to support the 910mm extended rod.
Material Ejection
Cycles formed parts out of a press area, relying on adjustable 21mm end cushions to decelerate the payload smoothly.
Replacing the Airtac SU32~50 Standard Cylinder SU50X910 with the SAU50X910
To replace this discontinued SU50X910, order the SAU50X910 drop-in equivalent, verifying your 1/4" port, M16x1.5 rod thread and SC-series mounting (LB/FA/FB/CA/CB). Because this 910mm stroke is long, use an external guide to prevent rod bending and side-load wear. For higher loads, neighbouring bores (63mm) offer 1559 N push at 0.5 MPa. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads. If self-switching is needed, the SAU line offers the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU50X910
- ✓ 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 SU50X910 FAQ
Yes, the SU50X910 is discontinued. The exact drop-in replacement is the AirTAC SAU50X910. It matches the 50mm bore, 910mm stroke, 982 N force, 1/4" port and SC-series mounting. The SAU body uses current CMSG/DMSG/EMSG sensors, and because this specific SU SKU lacks a magnet, it cannot accept a sensor switch anyway.
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa push is 1374 N, and the theoretical max is 200 kgf at 1.0 MPa. The safe working load is about 589 N. The air cushions only decelerate the load near stroke end; they do not hold position. If air is lost, the piston drifts, so you must use an external rod lock or pilot-operated check valve for load holding.
