About the Airtac SILF Front Locking Air Cylinder SILF200X80S
SILF200X80S specifies an 80 mm stroke of the 200 mm bore ISO 15552 end-lock cylinder, with the lock built into the front (rod-end) cover and the S suffix adding a magnet for position sensors. AirTAC has discontinued the SILF/SILB series, so this code is supplied as the current SAILF200X80S; every figure on this page describes that replacement unit.
Output is set by bore and pressure, not stroke: 15708 N push and 15080 N pull at 0.5 MPa, rising to 21991 N and 21112 N at 0.7 MPa. Ports are 3/4 PT, the rod thread is M36x2, cushions are adjustable, and the cylinder runs on filtered air from 0.15 to 1.0 MPa between -20 and +70 C at 30 to 500 mm/s.

How to choose
The 80 mm stroke sits 10 mm below the SILF200X90, so choose this code only when your travel is exactly 80 mm; the shorter body saves installed length and air per cycle. Compared with the plain SILF200X80, the S suffix adds the built-in magnet, so specify it only where position feedback is needed. This basic-body version mounts through the cylinder's own holes; add FA, FB or TC for front flange, rear flange or center trunnion mounting, or G for G (BSPP) threads.
Applications
Short-stroke pressing
The 80 mm travel suits pressing and staking stations where the front lock holds the rod out at the rod-end cover if air pressure is lost mid-cycle.
Monitored end positions
The built-in magnet lets you fit position sensors to confirm the rod is fully seated before the machine releases the part.
Vertical hold-safe slide
On a vertical axis, the front-cover lock keeps the load from dropping while the lock-side port is exhausted; air on that port or the manual lever releases it.
FAQ
What are the key figures of the SILF200X80S?
Bore 200 mm, rod 40 mm, stroke 80 mm, ISO 15552, double acting with end lock in the front cover and built-in magnet. Push 15708 N at 0.5 MPa and 21991 N at 0.7 MPa; pull 15080 N and 21112 N. Ports 3/4 PT, rod thread M36x2, 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.
Is the SILF200X80S still available?
AirTAC discontinued the SILF/SILB series, so the SILF200X80S is supplied as the current SAILF200X80S under the same order code. The specifications you receive are the SAILF200X80S figures listed on this page.
