This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X100CB, 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.

The AirTAC Airtac SU63-100 Standard Cylinder SU63X100CB is a double-acting profile-type standard cylinder with a Ø63mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X100CB, which matches its bore, stroke, force and mounting.
The AirTAC SU63X100CB is a discontinued double-acting profile-type cylinder featuring a 63 mm bore, 100 mm stroke, and a CB rear mount. Built with an extruded aluminum barrel, it is shorter and more compact than an ISO 15552 cylinder of the same bore, delivering 1559 N of push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU63X100CB, a direct replacement retaining the exact 3/8" port, M16x1.5 rod thread, and SC-series mounting interface.
Because this specific SKU lacks a magnet, it cannot accept a position switch. Upgrading to the SAU brings current CMSG/DMSG/EMSG sensor compatibility if you later need detection, plus a new SAUF built-in-valve option.

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.
Secures heavy workpieces in CNC machining fixtures, utilizing the 1559 N push force at 0.5 MPa for rigid holding during metal cutting.
Actuates sorting pop-up arms on packaging lines, where the 100 mm stroke provides the precise travel needed to redirect heavy cartons.
Controls heavy pallet flow on roller conveyors via the CB mount, safely decelerating loads using the adjustable 21 mm air cushions.
To replace this discontinued SU63X100CB, order the SAU63X100CB and confirm your 3/8" port, M16x1.5 rod thread, and CB mounting accessory. Since this SKU has no -S magnet, it cannot support sensing; if your machine now requires detection, specify an SAU with a magnet and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. Sizing both ways: dropping to a 50 mm bore yields 982 N push at 0.5 MPa, while stepping up to an 80 mm bore provides 2513 N. A plain cylinder drifts on air loss—the 21 mm cushions only decelerate the piston near stroke end—so install an external rod lock or pilot-operated check valve for held loads. At 100 mm stroke, rod bending is minimal, but always guide the load to prevent side-load wear.
Replacement checklist
Yes, the AirTAC SU63X100CB is discontinued. The direct replacement is the SAU63X100CB, which matches the 63 mm bore, 100 mm stroke, 3/8" port, output force, and CB mounting dimensions. You can install it without modifying your existing SC-series mounting hardware.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. Push force is 2182 N at 0.7 MPa and 2805 N at 0.9 MPa, with a theoretical max of 318 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot accept sensors; the SAU replacement supports CMSG/DMSG/EMSG switches if detection is added later.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X100CB replacement — usually within 7-8 hours.
