This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X100SLB, 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 SU40X100SLB
The AirTAC Airtac SU32~50 Standard Cylinder SU40X100SLB is a double-acting profile-type standard cylinder with a Ø40mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X100SLB, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X100SLB
The AirTAC SU40X100SLB is a discontinued double-acting profile-type cylinder with a 40mm bore and 100mm stroke, delivering 628N push and 528N pull at 0.5MPa. AirTAC replaced it with the SAU40X100SLB direct replacement: identical body, force, 1/4" port and SC-series LB mounting. This extruded aluminium barrel is more compact than an ISO 15552 cylinder of the same bore.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors replacing the legacy CS1-B/DS1-B switches on this -S model, and adds the SAUF built-in 4M valve variant. Note that a plain cylinder drifts on air loss; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X100SLB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X100SLB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU40X100SLB
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×100 | Stroke length in mm. |
| -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.
Where the Airtac SU32~50 Standard Cylinder SU40X100SLB Is Used
Small Parts Clamping
Ideal for securing 32kg workpieces in machining fixtures, utilising the 628N push force at 0.5MPa for reliable holding during milling.
Package Diverting
Drives a 100mm stroke diverter arm on packaging lines to route lightweight boxes, taking advantage of the compact profile body.
Pallet Stop Gate
Acts as a pneumatic stop gate in low-force material handling conveyors, safely halting pallets without tie-rod bulk.
Replacing the Airtac SU32~50 Standard Cylinder SU40X100SLB with the SAU40X100SLB
To replace this discontinued SU40X100SLB, order the SAU40X100SLB. Verify the 40mm bore, 100mm stroke, 1/4" port (PT/G/NPT) and SC-series LB mount. Because this SKU has the -S magnet, you must upgrade to CMSG/DMSG/EMSG sensors as the old CS1-B/DS1-B switches are obsolete. If sizing neighbours, a 32mm bore yields 402N push while a 50mm bore yields 982N at 0.5MPa. For load holding, remember the air cushion only decelerates; add a pilot-operated check valve or rod lock to prevent drift. If your machine needs self-switching, the SAUF valve-integrated variant is a new option. At 100mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same bore / stroke → SAU40X100SLB
- ✓ 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 SU40X100SLB FAQ
Yes, the SU40X100SLB is discontinued. The direct replacement is the SAU40X100SLB. It shares the same 40mm bore, 100mm stroke, 628N force, 1/4" port and LB mounting, but requires CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B.
The 40mm bore features a 1/4" port and M12x1.25 rod thread. It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, 1130N at 0.9MPa, and a theoretical max of 128kgf at 1.0MPa. Speed is 30-800mm/s.
