About the Airtac SILF Front Locking Air Cylinder SILF160X120
A 120 mm stroke keeps the body short while the 160 mm bore still produces the full force table: 10053 N push against 9425 N pull at 0.5 MPa, climbing to 14074 N and 13195 N at 0.7 MPa. Short travel means low air per cycle and a compact envelope that fits where metre-long codes cannot, yet the end lock still pins the piston at the front (rod-end) cover whenever the lock-side port is exhausted, releasing automatically with air or by hand lever.
This SILF160X120 is supplied as SAILF160X120 because AirTAC replaced the discontinued SILF/SILB series with SAILF/SAILB. What arrives carries the replacement's specification: 3/4 in PT ports, an M36x2 thread on the 40 mm rod, adjustable air cushions, air filtered by a 40 um element, 0.15 to 1.0 MPa operation (proof 1.5 MPa), -20 to +70 C, and 30 to 500 mm/s.

How to choose
Within the 160 mm end-lock range this is one of the shortest listed strokes; the same code with a longer travel, for example SILF160X1000, buys reach at the cost of body length and air use, and strokes beyond the 1500 mm catalog standard are quoted as non-standard up to 1800 mm. Add S (SILF160X120S) if a position sensor must read the rod. Mounting here is basic; FA front flange, TC center trunnion and FTC front trunnion cover rigid and pivoting installations, and G changes the threads to G (BSPP). The F fixes the lock at the front cover, the only lock position the catalog lists for this bore.
Applications
Fixture clamp and hold
A 120 mm stroke is enough to swing a clamp arm over the workpiece, and the front-cover lock keeps it clamped if air pressure drops mid-shift, with 14074 N of push available at 0.7 MPa for heavy clamp links.
Pallet stopper gate
Short-stroke stoppers that rise into a conveyor lane benefit from the end lock: the stopper stays up with the lock side exhausted, so a pallet cannot push it down during a supply loss.
Tooling retention
Punch and die retention or core placement in presses uses the compact body and M36x2 rod thread, with the lock holding the tool in position at the rod end until the machine sequence deliberately releases it.
FAQ
What are the key figures of the SILF160X120?
Bore 160 mm, rod 40 mm with M36x2 thread, stroke 120 mm, ports 3/4 in PT, push 10053 N and pull 9425 N at 0.5 MPa, push 14074 N and pull 13195 N at 0.7 MPa, operating pressure 0.15 to 1.0 MPa (proof 1.5 MPa), speed 30 to 500 mm/s, temperature -20 to +70 C, adjustable air cushions, air filtered by a 40 um element, front-cover lock with automatic and manual release.
Is the SILF160X120 still available as an original SIL-series part?
No. AirTAC discontinued the SILF/SILB series and supplies this order code as SAILF160X120, the identical code with the current SAILF/SAILB prefix; all figures on this page are those of the replacement cylinder delivered.
