About the Airtac SILF Front Locking Air Cylinder SILF160X300-S
Ordering SILF160X300-S buys a 160 mm bore ISO 15552 cylinder with 300 mm of travel, double acting, with a mechanical end lock set in the front (rod-end) cover and a built-in S magnet. Because AirTAC retired the SILF/SILB series, the code you receive is SAILF160X300S - same characters, new prefix - and the data below is the specification of that replacement cylinder.
At 300 mm this sits in the middle of the listed stroke range, so it trades body length against travel more evenly than the long-stroke codes. Output is set by the bore: 10053 N push and 9425 N pull at 0.5 MPa, rising to 14074 N push and 13195 N pull at 0.7 MPa. With the basic build the body mounts through its own holes; the front lock grips the piston whenever the lock-side 3/4 inch port is exhausted, air on that port frees it automatically, and a hand lever frees it by hand.

How to choose
Compare against its neighbours: SILF160X350-S gives 50 mm more travel at the cost of a longer body and more air per cycle, while shorter listed strokes start at 25 mm. If the load must be held at the rear cover instead, note that SILB codes are not listed for this bore - front locks are the offered option here. For a fixed mounting interface, order SILF160X300-FA, SILF160X300-TC or SILF160X300-FTC; for BSPP threads instead of PT, add the G port code; and dropping the S leaves the body without a magnet.
Applications
Hold at end of stroke
The front-cover lock keeps the rod extended through the whole 300 mm stroke when the lock-side port is vented, even with no air supply.
Position-checked release
The S magnet lets a sensor verify piston position before the machine logic allows the next move, on a cylinder running 30 to 500 mm/s.
Packaging push-and-dwell
A 300 mm feed carries product into a station; adjustable air cushions soften the stop while the lock holds the rod for the dwell period.
FAQ
What are the key figures of the SILF160X300-S?
160 mm bore, 40 mm piston rod, M36x2 rod thread, 300 mm stroke, double acting with end lock at the front cover, built-in S magnet, basic build, 3/4 inch PT ports. Push 10053 N and pull 9425 N at 0.5 MPa; push 14074 N and pull 13195 N at 0.7 MPa. Pressure 0.15 to 1.0 MPa (proof 1.5 MPa), -20 to +70 C, 30 to 500 mm/s, adjustable air cushions, air filtered by a 40 um element.
Does the SILF160X300-S ship as a current-series cylinder?
Yes. The SILF/SILB series is discontinued and replaced by SAILF/SAILB, so SILF160X300-S is supplied as SAILF160X300S under the same code with the new prefix. Every specification, including the front lock, the S magnet and the basic build, describes the SAILF cylinder you receive, not an old-series unit.
