About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X165
The AirTAC SC160X165 is a double-acting tie-rod cylinder delivering substantial force in a compact 165 mm stroke. At 0.5 MPa it provides 10053 N pushing and 9425 N pulling, scaling up to a powerful 18095 N at the maximum operating pressure of 0.9 MPa.
This model features a 40 mm diameter piston rod with an M36x2 knuckle thread and a 29 mm adjustable air cushion at each end to decelerate heavy loads smoothly. The body length A is 239 mm, giving a total extended length of approximately 404 mm. Standard PT3/8 ports and TPU seals suit filtered-air systems from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X165 Is Used
Heavy Press & Clamping
The 18095 N thrust at 0.9 MPa makes the SC160X165 ideal for hydraulic-press alternatives, heavy-duty clamping fixtures, and riveting stations where a short, powerful stroke is needed.
Pallet & Bale Handling
With 10053 N of push force at standard shop air, this cylinder reliably actuates pallet turntables, bale ejectors, and large diverter gates on heavy-material conveyors.
Mould & Die Actuation
Use the SC160X165 for core pulls, stripper plates, or die-casting ejectors. The adjustable cushion protects tooling by decelerating the 40 mm rod and heavy payload before end-of-stroke impact.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X165 the Right Cylinder?
Choose the SC160 bore when your application needs between roughly 10000 N and 18000 N of pneumatic force. If your load is lighter, stepping down to an SC125 bore (6136 N at 0.5 MPa) can reduce air consumption and physical size. For strokes over 300 mm, consider external guides or a guided cylinder to protect the 40 mm rod from side-load bending moments.
To replace an existing cylinder, match five points: 160 mm bore, 165 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and confirm whether a magnet is required. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC160 tie-rod units.
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 AIRTAC SC125-160 Standard Cylinder SC160X165 FAQ
At 0.7 MPa the SC160 bore generates a theoretical push force of 14074 N. The pull force on the return stroke is lower due to the 40 mm rod area, delivering 9425 N at 0.5 MPa. Always apply a safety factor for real-world dynamic loads.
This basic model SC160X165 ships without mounting accessories. You can order a centre trunnion kit separately using part code F-SC160TC, which includes the TCM1 bracket for pivoting applications. The mounting suffix would be added to the model code (e.g., SC160X165TC) if ordered pre-assembled from the factory.
