About the Airtac SC50 Standard Cylinder SC50X825
The AirTAC SC50X825 pneumatic cylinder provides a 50 mm bore and 825 mm stroke in a rugged tie-rod design. Operating at 0.5 MPa, it generates 982 N of push force and 825 N on the pull stroke, with a maximum thrust of 1767 N at 0.9 MPa. The 20 mm diameter piston rod and 21 mm adjustable air cushion ensure reliable deceleration at end-of-travel.
This genuine AirTAC SC model is shorter than an ISO 15552 cylinder, making it a direct fit for existing SC50 installations. The body length A is 150 mm, giving an extended length of approximately 975 mm. Standard PT1/4 ports and M16x1.5 rod thread simplify pneumatic connections and tooling attachment.

Where the Airtac SC50 Standard Cylinder SC50X825 Is Used
Long-Reach Part Transfer
The 825 mm stroke moves components between distant stations on assembly or packaging lines, with 982 N of force handling medium-weight payloads.
Hopper Gate Actuation
Operates slide gates on bulk material hoppers or chutes, where the extended reach allows the cylinder body to be mounted clear of the material flow.
Clamping & Fixturing
Provides consistent clamping force for large jigs or welding fixtures, with the adjustable cushion absorbing shock at the end of the 825 mm travel.
Is the Airtac SC50 Standard Cylinder SC50X825 the Right Cylinder?
Select the SC50X825 for applications needing 982 N at 0.5 MPa. If force is marginal, stepping up to a 63 mm bore (SC63 series) provides 1559 N at the same pressure. For strokes of 825 mm, verify the rod is adequately supported against side loads; an external guide or guided cylinder is recommended to prevent rod bending and premature bearing wear.
Replacement must match five points: 50 mm bore, 825 mm stroke, PT1/4 port thread, basic mounting (no brackets), and no magnet. This cylinder is a direct swap for another AirTAC SC50 of identical configuration.
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 SC50 Standard Cylinder SC50X825 FAQ
At 0.7 MPa (7 bar) operating pressure, the SC50X825 produces 1374 N of push force. The maximum force at 0.9 MPa is 1767 N.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is a direct replacement only for another AirTAC SC50 with matching bore, stroke, port thread, and mounting.
