About the Airtac SILF Front Locking Air Cylinder SILF125X60S
The AirTAC SILF125X60S is the short-stroke, sensor-ready member of the 125 mm bore end-lock family: 60 mm of travel, a piston magnet for position switches, and the end lock set in the front (rod-end) cover so the piston is held there while the lock-side port is exhausted. The SILF/SILB series is discontinued; this code is supplied as the current SAILF125X60S, and the figures below are those of the replacement unit you receive.
Despite the compact stroke, the 125 mm bore produces full-size force: 6136 N push and 5734 N pull at 0.5 MPa, rising to 8590 N / 8027 N at 0.7 MPa. It runs on filtered air from 0.15 to 1.0 MPa (proof 1.5 MPa) between -20 and +70 C at 30 to 800 mm/s, with adjustable air cushions, 1/2 inch PT ports and an M27x2 thread on the 32 mm rod.

How to choose
Pick SILF125X60S when a 60 mm clamp or positioning move must be monitored and held at the rod end; plain SILF125X60 omits the magnet and SILB125X60S moves the lock to the rear cover. Basic mounting keeps the envelope minimal - switch to SILF125X60S with LB, FA, CB, TC or FTC added for foot, flange, clevis or trunnion mounting, or add G for BSPP ports instead of the standard PT.
Applications
Short-stroke heavy clamping
Clamps fixtures with up to 8590 N at 0.7 MPa over a 60 mm stroke, the magnet confirming the fully clamped position to the controller each cycle.
Part presence verification
Uses the 60 mm probe motion and piston-magnet switches to prove a part is seated before a machining or assembly step is allowed to start.
Lock-and-hold fixture positioning
Positions a nest or stopper in a 60 mm move, with the front-cover end lock holding it against an air-supply failure until air returns or the lever releases it.
FAQ
What are the key figures for the SILF125X60S?
Stroke 60 mm, bore 125 mm, rod 32 mm with M27x2 thread, ports 1/2 inch PT, operating pressure 0.15 to 1.0 MPa (proof 1.5 MPa), temperature -20 to +70 C, speed 30 to 800 mm/s, adjustable air cushions, built-in magnet for position sensors, front (rod-end) lock. Output: 6136 N push / 5734 N pull at 0.5 MPa; 8590 N / 8027 N at 0.7 MPa.
Is the SILF125X60S discontinued?
The SILF/SILB series has been discontinued by AirTAC, so ordering SILF125X60S gets you the current SAILF125X60S - the same code with the new prefix. All specifications on this page are those of that replacement unit.
