About the Airtac SC80 Standard Cylinder SC80X915
The AirTAC SC80X915 is a double-acting tie-rod cylinder delivering a substantial 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a long 915 mm stroke, it features a 25 mm diameter piston rod and a 28 mm adjustable air cushion at each end to decelerate the load smoothly.
This model has a total body length of 182 mm (dimension A) plus the 915 mm stroke, resulting in a significant extended length. The standard PT3/8 port and M20x1.5 rod thread are included. As a genuine AirTAC SC series cylinder, it is built for reliable, high-cycle linear motion in industrial automation.

Where the Airtac SC80 Standard Cylinder SC80X915 Is Used
Pallet Transfer
Pushes heavy pallets across a roller conveyor section. The 915 mm stroke covers the full transfer distance, and the 2513 N force at 0.5 MPa easily moves loaded pallets.
Press Feed Mechanism
Advances large sheet metal blanks into a stamping press. The long stroke positions material accurately, while the adjustable cushion prevents bounce at the end of travel.
Grain Chute Diverter
Actuates a large diverter gate in an agricultural processing line. The cylinder's force overcomes material buildup, and the tie-rod design handles dusty environments.
Is the Airtac SC80 Standard Cylinder SC80X915 the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the 63 mm bore SC63 series, which provides 1559 N of push force at 0.5 MPa. For higher force demands, the 100 mm bore SC100 series offers 3927 N at the same pressure. Always ensure the mounting and rod are aligned to prevent side loading.
Given the 915 mm stroke, managing rod deflection is critical. Any side load on the unsupported 25 mm rod can cause bending and premature seal wear. For this stroke length, it is strongly recommended to use an external guide rail or a guided cylinder assembly to absorb transverse forces. When replacing, match the 80 mm bore, 915 mm stroke, PT3/8 port thread, basic mounting configuration, and the absence of a magnet.
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 SC80X915 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
A stroke of 915 mm with a 25 mm rod is susceptible to bending under side loads. You must guide the load externally with a linear rail or rod guide. The cylinder should only handle axial push/pull forces; any misalignment or transverse load will damage the rod bearing and seals.
