This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X75H — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X75H in place of this model. 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 SUD Series Double Rod Cylinder SUD63X75H
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X75H is a double-acting profile-type standard cylinder with a Ø63mm bore and 75mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X75H, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X75H
The AirTAC SUD63X75H is a double-acting, double-rod profile cylinder featuring a 63mm bore and 75mm stroke. A rod exits both ends on a single piston, meaning push and pull forces are equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This SUD model is discontinued; the exact drop-in replacement is the SAUD63X75H, which matches the 3/8" port, M16x1.5 rod thread, and basic/FA/LB mounting. The H suffix indicates Viton/FKM seals for 0 to 150 C high-temperature environments.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, double-rod designs excel at anti-rotation and compact dual-workstation tasks. This non-magnetic SKU cannot accept a piston switch, though the SAUD successor upgrades to CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B. For sizing, the safe working load is roughly 841 N (60% of the 0.5 MPa force), allowing a vertical lift of about 71 kg with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X75H 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 SAUD63X75H 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 SUD Series Double Rod Cylinder SUD63X75H Is Used
Dual-Station Transfer
Drives two opposing tools or fixtures simultaneously using both extending rods, ensuring perfectly synchronized part transfer in compact assembly cells.
High-Temp Lift
Handles vertical lifting up to 71 kg with a 2:1 safety margin in hot environments up to 150 C, utilizing the Viton H seals to prevent degradation.
Anti-Rotation Guidance
The twin-rod architecture resists torsional twisting without external guide rails, maintaining precise alignment for clamping and pressing tasks.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X75H with the SAUD63X75H
To replace the discontinued SUD63X75H, specify the SAUD63X75H as a direct drop-in, retaining the 63mm bore, 75mm stroke, 3/8" port, and FA/LB mounting. Size both directions by checking the equal both-ways force against your load, stepping to neighbour bores (50mm or 80mm) if a different capacity is needed. Choose a double-rod cylinder when you need anti-rotation guidance, dual-tool driving, or a rear cam. Because this SKU lacks a magnet (-S), it cannot take a sensor; the SAUD upgrade uses CMSG/DMSG/EMSG switches. For strokes >=300mm, verify side-load bearing limits. A plain cylinder does not hold loads on air loss—the cushion only decelerates—so add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X75H
- ✓ 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 SUD Series Double Rod Cylinder SUD63X75H FAQ
Yes, the SUD63X75H is discontinued. The exact drop-in replacement is the SAUD63X75H, which matches the 63mm bore, 75mm stroke, 3/8" port, and FA/LB mounting. The SAUD also adds compatibility with current CMSG/DMSG/EMSG sensors and offers an SAUF built-in-valve variant.
Because it is a double-rod cylinder, the push and pull forces are equal both ways: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The air port is 3/8" (PT thread standard) with an M16x1.5 rod-end thread. It operates at 0.15-1.0 MPa with adjustable 21mm cushions at each end.
