About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X750H
The AirTAC SC160X750H is a double-acting single-rod tie-rod cylinder with a 160 mm bore and 750 mm stroke, built for high-force industrial actuation. At 0.5 MPa air pressure it generates 10053 N pushing force, rising to 18095 N at the maximum operating pressure of 0.9 MPa, driven by a 40 mm diameter piston rod with M36x2 male threads.
This model is fitted with Viton (FKM) seals, extending the operating temperature range to 0–150 °C for hot or chemically aggressive environments. The cylinder body length A is 239 mm, giving a total extended length of approximately 989 mm. Adjustable pneumatic cushioning at both ends decelerates the piston over a 29 mm cushion length, protecting end caps during high-speed cycles.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X750H Is Used
Sawmill & Timber Processing
The 160 mm bore delivers the sustained force needed for log clamping, veneer pressing, and carriage drives. Viton seals withstand the heat and dust common in drying kilns and planer mills.
Heavy Agricultural Machinery
Provides reliable actuation for large bale handlers, silage compactors, and fertiliser spreader gates. The 0–150 °C Viton seal range handles engine-bay and hydraulic-compartment heat without degradation.
Scrap & Recycling Balers
Generates 18 kN of compaction force at 0.9 MPa for crushing and baling metal turnings, cardboard, or plastic waste. The adjustable cushion absorbs shock as the ram hits the material charge.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X750H the Right Cylinder?
Choose the SC160 bore when your application needs push force in the 10000–18000 N class at standard plant air pressures. If your load is lighter, stepping down to the SC125 bore (6136 N push at 0.5 MPa) can reduce air consumption and physical size. For heavier loads, the SC200 bore provides 15708 N at 0.5 MPa.
At 750 mm stroke, the 40 mm rod is well-supported for axial loads, but any significant side force requires an external linear guide or a guided cylinder to prevent rod bearing wear and bending. When replacing an existing cylinder, match five points exactly: 160 mm bore, 750 mm stroke, PT port thread, basic mounting (no bracket), and confirm the seal material—this H-suffix model uses Viton for high-temperature compatibility.
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 SC160X750H FAQ
At 0.7 MPa (7 bar) the SC160 bore produces 14074 N pushing force and approximately 13195 N pulling force. At the maximum operating pressure of 0.9 MPa, push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf (20098 N).
No. The SC160 is a standard double-acting cylinder—it does not lock or hold position when air pressure is exhausted or the directional valve is centered. The piston will drift or drop under load. If you need to hold a position without live pressure, you must add an external rod lock, a pilot-operated check valve, or use a mechanical brake.
