This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X850TC, 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 SU63X850TC
The AirTAC SU63-100 Standard Cylinder SU63X850TC is a double-acting profile-type standard cylinder with a Ø63mm bore and 850mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X850TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X850TC
The AirTAC SU63X850TC is a discontinued double-acting profile-type cylinder with an 850 mm stroke and 63 mm bore. It delivers 1559 N push and 1402 N pull at 0.5 MPa, operating via a 3/8" port. AirTAC replaced this legacy unit with the SAU63X850TC, a direct alternative retaining the exact bore, stroke, force, port size, and SC-series TC mounting interface.
Because this SKU lacks a magnet, it cannot accept a sensing switch. The SAU upgrade also shifts to current CMSG/DMSG/EMSG sensors for magnetized versions and introduces the SAUF built-in 4M valve variant the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X850TC 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 SAU63X850TC 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 SU63X850TC Is Used
Long-Stroke Diversion
Pushes heavy pallets sideways on a 63 mm bore line using the 850 mm extension, relying on the TC mount for stable pivoting during transit.
Heavy Part Ejection
Clears machined metal components from a press bed, using the 1559 N push force and adjustable end cushions to decelerate the mass.
Replacing the Airtac SU63-100 Standard Cylinder SU63X850TC with the SAU63X850TC
To replace this SU63X850TC, order the SAU63X850TC. Verify your 3/8" port, M16x1.5 rod thread, and TC mounting accessory are retained. If moving down, a 50 mm bore gives 982 N push at 0.5 MPa; sizing up to 80 mm yields 2513 N. Because this 850 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load damage. A plain cylinder drifts without live air—the 21 mm cushions only decelerate—so add an external rod lock or pilot-operated check valve for load holding. The non-magnetized body cannot take sensors.
Replacement checklist
- ✓ Same bore / stroke → SAU63X850TC
- ✓ 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 SU63X850TC FAQ
Yes, the SU63X850TC is discontinued. The direct replacement is the SAU63X850TC. It matches the 63 mm bore, 850 mm stroke, 3/8" port, force, and TC mounting. The SAU family also adds a SAUF valve-integrated option.
It provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf maximum at 1.0 MPa. This specific SKU has no magnet and cannot take a switch. Magnetized SAU replacements use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
