About the Airtac SILF Front Locking Air Cylinder SILF200X200
The SILF200X200 pairs a 200 mm bore with an equal 200 mm stroke and the front-cover end lock, ordered without the S magnet, so no position sensor can read the piston directly from the cylinder. AirTAC has replaced the SILF/SILB series with SAILF/SAILB, and this code ships as SAILF200X200 - identical code, current prefix - with the SAILF specifications below applying to the delivered unit.
Output is set by bore and pressure alone: 15708 N push and 15080 N pull at 0.5 MPa, rising to 21991 N and 21112 N at 0.7 MPa. The lock in the rod-end cover holds the piston while that side's port is exhausted and releases on air pressure or by hand lever. Shared hardware includes 3/4 inch PT ports, an M36x2 rod thread on the 40 mm rod and adjustable air cushions, running on filtered air at 0.15 to 1.0 MPa (proof 1.5 MPa), -20 to +70 C, at 30 to 500 mm/s.

How to choose
The nearest sibling is SILF200X200S, which adds the S magnet for position sensors - take it if a PLC must confirm rod position; SILF200X175S cuts the stroke to 175 mm for a shorter installed length. All three keep basic mounting on the cylinder body, while FA, FB and TC codes add front-flange, rear-flange or center-trunnion fixing. A G in the order code changes the ports from PT to G (BSPP), and a SILB code relocates the lock to the rear cover.
Applications
Heavy gate or diverter actuation
A 200 mm stroke sweeps a heavy gate or product diverter fully open and closed, with the front-cover lock holding it in position if plant air is lost; switching is handled by machine-mounted proximity switches outside the cylinder.
Stamping and riveting ram
21991 N of push at 0.7 MPa gives a stamping or riveting head serious working force over a 200 mm approach, with adjustable air cushions softening the return stroke.
Vertical riser parked at the rod end
Mounted upright with the lock in the front cover, the rod holds its raised position during a power loss and can be lowered manually with the release lever for safe servicing.
FAQ
What are the key figures for the SILF200X200?
Bore 200 mm, stroke 200 mm, double acting with the end lock in the front cover and no magnet. Ports 3/4 inch PT, rod thread M36x2 on a 40 mm rod. 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, basic mounting. Push 15708 N and pull 15080 N at 0.5 MPa; 21991 N and 21112 N at 0.7 MPa.
Is the SILF series still available from AirTAC?
No - AirTAC discontinued the SILF/SILB series and supplies SILF200X200 as the current SAILF200X200, same code after the prefix. The specifications listed here are those of the replacement SAILF cylinder the buyer receives.
