About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50FA
The AirTAC SC160X50FA is a double-acting tie-rod cylinder with a 160 mm bore and a short 50 mm stroke, pre-assembled with a front rectangular flange (FA) for rigid panel mounting. At 0.5 MPa air pressure it generates 10053 N of push force, making it suitable for compact high-force clamping or pressing tasks.
The piston rod is a robust 40 mm diameter with an M36x2 male knuckle thread. The cylinder body length (A) is 239 mm, and the adjustable air cushion at each end (29 mm length) decelerates the 40 mm rod smoothly. Ports are PT3/4, and the standard TPU seals operate from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50FA Is Used
Heavy-Duty Clamping
The 10053 N push force at 0.5 MPa (up to 18095 N at 0.9 MPa) makes the SC160X50FA ideal for pneumatic clamping fixtures on welding or assembly lines where a short, rigid stroke is needed.
Press-Fit Assembly
Delivers a controlled 50 mm stroke for pressing bearings, bushings, or pins into housings. The front flange mount ensures the cylinder body stays perfectly aligned under high thrust.
Die Cushion / Stripper Plate
Used as a short-stroke pneumatic cushion or stripper in metal forming tools. The 40 mm rod and adjustable cushion handle the high cycle rates and impact forces reliably.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50FA the Right Cylinder?
This 160 mm bore model produces 10053 N at 0.5 MPa. If your load requires less force, stepping down to a 125 mm bore saves space and air consumption (6136 N push at 0.5 MPa). For higher force, the 200 mm bore delivers 15708 N at the same pressure. The 50 mm stroke is standard; confirm the front flange mounting hole pattern matches your machine using the F-SC160FA accessory drawing.
When replacing an existing cylinder, match five points: 160 mm bore, 50 mm stroke, PT3/4 port thread, the FA front flange mounting, and confirm no magnet is required (this model has no built-in 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 AIRTAC SC125-160 Standard Cylinder SC160X50FA FAQ
At 0.7 MPa supply pressure, the theoretical push force is 14074 N. The pull force on the retract stroke is 9425 N at 0.5 MPa, due to the 40 mm rod reducing the piston area on the rod side.
No, the FA front flange is designed for rigid, fixed mounting on a panel or machine face. If your application requires the cylinder body to pivot, consider a rear clevis (CA or CB) or centre trunnion (TC) mount instead. The mounting accessory must be specified at order; it is not field-convertible.
