Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X210-75
The AirTAC Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X210-75 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 210mm stroke, 3/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X210-75
The AirTAC SAUJ63X210-75 is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment window of 75 mm. You can trim the usable extend stroke from the 210 mm maximum down to 135 mm via an external stop screw, eliminating the need to buy a new cylinder for minor position changes. It features a 3/8" port and an M16x1.5 rod thread. The extruded aluminum profile barrel makes it shorter than an ISO 15552 unit of the same bore.
In the 63 mm bore class, this cylinder delivers a push force of 1559 N and a pull force of 1402 N at 0.5 MPa, with a theoretical maximum of 318 kgf at 1.0 MPa. For design sizing, the safe working load is roughly 935 N (about 60 percent of the 0.5 MPa push figure), and it can handle a vertical lift of approximately 79 kg with a 2:1 safety margin. It includes adjustable air cushions and supports basic, FA, and LB mountings.

Where the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X210-75 Is Used
Variable Pitch Indexing
Allows operators to fine-tune the extend stroke by up to 75 mm on-site to dial in exact material pitch without swapping out the entire actuator.
Adjustable Transfer Pusher
Accommodates changing package sizes on a line by shorting the extend stroke from 210 mm down to 135 mm to hit different stop positions.
Variable Depth Sealing Jig
Provides the precise extend end-position tuning needed when sealing cartons of varying depths, using the external screw to set the exact travel.
Is the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X210-75 the Right Cylinder?
When sizing this unit, look at both neighboring bores and the 0.5 MPa forces: the 50 mm bore gives 982 N push, while the 80 mm bore yields 2513 N. The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, making it a solid middle ground. Choose the SAUJ over a fixed SAU cylinder when your machine build requires field tuning of the extend end position; here, the 75 mm stop screw window lets you dial in the stroke exactly. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG sensors. For non-locking guidance, since the 210 mm stroke is under 300 mm, side-load risks are moderate, but always guide the load externally. Remember the stop screw sets the end position but does not lock the load.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X210-75 FAQ
At 0.5 MPa it provides 1559 N push and 1402 N pull force. Push rises to 2182 N at 0.7 MPa, 2805 N at 0.9 MPa, and a theoretical max of 318 kgf at 1.0 MPa. The nominal stroke is 210 mm, but the external stop screw lets you shorten the extend stroke by up to 75 mm, yielding a usable extend range of 135-210 mm.
An external stop screw physically limits the piston's extend travel, letting you trim the stroke on-site. This stop sets the end position but is not a load lock. A plain cylinder will drift on air loss or when the valve is centered; the air cushion only decelerates the piston near the end of travel. For secure load holding, use an external rod lock or a pilot-operated check valve.
