About the Airtac SC100 Standard Cylinder SC100X838S
The SC100X838S is a double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). Its 25 mm diameter piston rod and 29 mm adjustable air cushion provide smooth deceleration across the full 838 mm stroke.
This model includes a built-in magnet (-S suffix), enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for contactless position feedback. The body length A is 188 mm, giving a total extended length of approximately 1026 mm.

Where the Airtac SC100 Standard Cylinder SC100X838S Is Used
Material Handling Pusher
The 838 mm stroke and 3927 N push force at 0.5 MPa make this cylinder ideal for pushing heavy pallets or totes across wide conveyor transfer stations.
Automated Welding Clamp
With a built-in magnet for sensor feedback, this cylinder confirms clamp position in automated welding cells, handling high-cycle clamping of large fabrications.
Dock Leveler Actuation
The long 838 mm stroke and robust 25 mm rod suit dock leveler lip extension, where the adjustable cushion absorbs impact at full extension.
Is the Airtac SC100 Standard Cylinder SC100X838S the Right Cylinder?
For higher force, step up to the 125 mm bore (6136 N push at 0.5 MPa); for a lighter, more compact option, the 80 mm bore provides 2513 N. At 838 mm stroke, the piston rod is long and unsupported—external guides or a guided cylinder are recommended to prevent rod bending under side loads. When replacing an existing cylinder, match all five points: 100 mm bore, 838 mm stroke, PT port thread, the built-in magnet (-S), and basic mounting.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC100 Standard Cylinder SC100X838S FAQ
At 0.7 MPa operating pressure, the SC100X838S produces 5497 N of push force (extending) and 3681 N of pull force (retracting), based on the 100 mm bore and 25 mm rod diameter.
Yes. The -S suffix indicates a built-in magnet in the piston, so you can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position.
