About the Airtac SC80 Standard Cylinder SC80X633
The AirTAC SC80X633 is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa). Its 80 mm bore and 633 mm stroke suit mid-range automation tasks requiring substantial thrust over a moderate distance.
This tie-rod cylinder features a 25 mm diameter piston rod, PT3/8 ports, and a 28 mm adjustable air cushion at each end. The total body length A is 182 mm, giving an extended length of approximately 815 mm. It operates on filtered air from 0.15 to 1.0 MPa across -20 to +70 °C with standard TPU seals.

Where the Airtac SC80 Standard Cylinder SC80X633 Is Used
Conveyor Diverter Gates
Actuates medium-duty diverter gates on packaging and sortation conveyors, using the 633 mm stroke to sweep products between lanes with reliable force.
Press-Fit Assembly Stations
Provides the 2513 N push force at 0.5 MPa needed for pressing bearings, bushings, or pins into housings in semi-automated assembly cells.
Pallet Layer Positioning
Moves a pallet stop or layer-forming plate through a 633 mm travel, positioning loads accurately in palletising machinery.
Is the Airtac SC80 Standard Cylinder SC80X633 the Right Cylinder?
Choose the SC80 bore when your application needs 2513 N at 0.5 MPa—stepping down to the SC63 bore provides 1559 N, while moving up to the SC100 bore delivers 3927 N at the same pressure. For this 633 mm stroke, ensure the rod is not subjected to significant side loading; an external linear guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five points exactly: 80 mm bore, 633 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and the absence of a magnet. This model is a standard tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80 Standard Cylinder SC80X633 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 2513 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80X633 has a 25 mm rod and a 633 mm stroke; applying side load directly to the rod end can cause bending and seal damage. For side-load applications, use an external linear guide rail or select a guided cylinder variant to absorb transverse forces.
