This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X435SH, 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 SU63-100 Standard Cylinder SU63X435SH
The AirTAC SU63-100 Standard Cylinder SU63X435SH is a double-acting profile-type standard cylinder with a Ø63mm bore and 435mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X435SH, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X435SH
The AirTAC SU63X435SH is a discontinued double-acting profile-type cylinder with a 63 mm bore and 435 mm stroke. Delivering 1559 N push at 0.5 MPa, its direct replacement is the SAU63X435SH, retaining the same body dimensions, 3/8" port, M16x1.5 rod thread, and SC-series mounting compatibility.
This high-temp (-H) Viton-sealed unit handles 0-150 C environments. Note the -S magnet functioned with legacy CS1-B/DS1-B switches, whereas the SAU upgrade utilizes current CMSG/DMSG/EMSG sensors and introduces a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X435SH carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X435SH 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 SU63-100 Standard Cylinder SU63X435SH Is Used
Hot End Ejection
Ideal for pushing parts at elevated ambient temperatures up to 150 C using the Viton H seal, delivering a safe 935 N working load.
435mm Transfer Arm
Executes mid-range product diversion on thermal processing lines, requiring external guides to manage rod bending over the long stroke.
Replacing the Airtac SU63-100 Standard Cylinder SU63X435SH with the SAU63X435SH
To replace this discontinued SU63X435SH, order the SAU63X435SH direct equivalent, verifying your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. Because the -S magnet is present, prepare to swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors on the SAU. The -H Viton seal provides 0-150 C heat resistance. For the 435 mm stroke, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts without air; use a pilot-operated check valve or rod lock to hold loads. If downsizing, a 50 mm bore yields 982 N push at 0.5 MPa; if upsizing, an 80 mm bore provides 2513 N. The SAUF variant offers a built-in 4M solenoid valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X435SH
- ✓ 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 SU63-100 Standard Cylinder SU63X435SH FAQ
Yes, the SU63X435SH is discontinued. The direct replacement is the SAU63X435SH. It matches the 63 mm bore, 435 mm stroke, 1559 N force, 3/8" port, and SC-series mounting. The SAU body is identical, though you must upgrade legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches.
The 3/8" port bore 63 mm cylinder provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical max of 318 kgf at 1.0 MPa. The cushion only decelerates the load; it does not hold position without live air, so use an external rod lock for vertical holding.
