Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X100-20S
The AirTAC Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X100-20S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 100mm 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 SAUJ63X100-20S
The SAUJ63X100-20S is a double-acting single-rod profile cylinder with a 63 mm bore and a 100 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable working range of 80-100 mm without buying a new actuator. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8" port, an M16x1.5 rod thread, and a built-in piston magnet (-S) for CMSG, DMSG, or EMSG sensors.
In the 63 mm class, this actuator delivers 1559 N push and 1402 N pull at 0.5 MPa, reaching 2805 N push at 0.9 MPa. A practical computed insight: the safe working load is roughly 935 N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of approximately 79 kg with a 2:1 safety margin. The external stop sets the end position but is not a load lock; the adjustable air cushions only decelerate the piston near the ends.

Where the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X100-20S Is Used
Variable Pitch Pusher
A packaging line that handles varying carton widths uses the 20 mm on-site stroke adjustment to perfectly time the push distance without swapping actuators.
Adjustable Diverter Arm
A conveyor sorting station utilizes the magnetic piston and field-tunable extend stroke to alter the diversion angle for different product sizes on the fly.
Tiered Stacking Stop
A palletizing cell employs the external stop screw to precisely set varying stacking heights, relying on the 1559 N push force to position heavy loads.
Is the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X100-20S the Right Cylinder?
When sizing this 63 mm bore actuator, consider the neighboring bores: a 50 mm bore provides 982 N push at 0.5 MPa, while an 80 mm bore yields 2513 N. The SAUJ format is ideal when you need field stroke tuning, replacing the hassle of a fixed-stroke SAU cylinder plus an external mechanical stop. You can select FA flange or LB foot mounts, with mounting compatibility matching the AirTAC SC series only. The -S suffix ensures you have the piston magnet required for CMSG/DMSG/EMSG electronic or reed switches. Because the 100 mm stroke is under 300 mm, side-load guide requirements are minimal, but always ensure rigid mounting to prevent binding.
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 SAUJ63X100-20S FAQ
At 0.5 MPa, the 63 mm bore provides 1559 N push and 1402 N pull. 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. The nominal 100 mm extend stroke is the maximum; the external stop screw lets you shorten it by up to 20 mm on-site, giving a usable range of 80-100 mm. It uses a 3/8" port and operates at 30-800 mm/s.
The -S suffix means the piston has a built-in magnet for direct mounting of CMSG, DMSG, or EMSG sensors for position detection. The external stop screw mechanically limits the final extend position to trim the stroke. This stop only sets the end position; it is not a load lock. The cylinder will drift on air loss, so use an external rod lock or pilot-operated check valve if you need to hold a load vertically.
