About the Airtac SILF Front Locking Air Cylinder SILF160X350-S
The SILF160X350-S orders a double-acting ISO 15552 end-lock cylinder with a 160 mm bore, a 350 mm stroke, the lock in the front (rod-end) cover and a built-in S magnet for position sensors. AirTAC has discontinued the SILF/SILB series, so this code ships as SAILF160X350S - the same code under the current prefix - and every figure here describes the replacement unit you receive.
The basic build carries no mounting code, so the body is held by its own mounting holes and your fixture defines the alignment. At 350 mm this is a long-travel cylinder: the extra body length adds air consumption but no output, which stays 10053 N push and 9425 N pull at 0.5 MPa, or 14074 N push at 0.7 MPa. The lock holds the piston while the lock-side 3/4 inch port is exhausted, releases automatically when air returns, and a hand lever releases it manually.

How to choose
Start with travel: 350 mm sits one step above the 300 mm SILF160X300-S, and longer listed lengths run up to 1800 mm, with catalog standard strokes to 1500 mm. Because force depends on bore and pressure only, stepping down to 300 mm saves length and air without losing force. If you need a rigid fixture interface instead of the basic body, order SILF160X350-FA (front flange), SILF160X350-TC (center trunnion) or SILF160X350-FTC (front trunnion), and add G for G (BSPP) ports instead of the PT standard. Rear-lock SILB codes are not offered for this bore - the catalog lists front locks only.
Applications
Vertical rod support on air loss
On a vertical slide, the front lock holds the 40 mm rod extended at the front cover if supply pressure drops, over the full 350 mm of travel.
Long-reach press fixture
A 350 mm approach stroke carries the tool to the work, and 14074 N push at 0.7 MPa with adjustable air cushions gives a controlled, damped landing.
Sensor-confirmed dwell
The built-in S magnet lets a position sensor confirm the piston is seated at the front cover before the next machine cycle is released.

Push is 10053 N and pull 9425 N at 0.5 MPa; push rises to 14074 N at 0.7 MPa. Working pressure 0.15 to 1.0 MPa (proof 1.5 MPa), temperature -20 to +70 C, speed 30 to 500 mm/s, adjustable air cushions, air filtered by a 40 um element.
I ordered a SILF code - what actually arrives?
AirTAC discontinued the SILF/SILB series and replaced it with SAILF/SAILB, so SILF160X350-S is supplied as SAILF160X350S, the identical order code under the current series prefix. All specifications you receive are those of the SAILF unit, including the front-cover lock, the S magnet and the basic build. Older hyphenated codes are the same code, so nothing on your drawing changes.
