About the Airtac SILF Front Locking Air Cylinder SILF200X500S
Ordering the SILF200X500S gets you the 500 mm travel member of the AirTAC 200 mm bore end-lock family, supplied as SAILF200X500S because the SILF/SILB series is discontinued and AirTAC ships each code under the current SAILF prefix with the same suffix. The SAILF200X500S you receive carries every specification shown here.
The S option builds a position-sensing magnet into the piston, so switches mounted on the barrel can report rod position along the full 500 mm of travel - valuable when a long slide must prove it is fully retracted before the front lock is relied on. Stroke and magnet change nothing about output: the 200 mm bore still delivers 15708 N push and 15080 N pull at 0.5 MPa, or 21991 N and 21112 N at 0.7 MPa, fed through 3/4 inch PT ports with adjustable air cushions at both ends.

How to choose
At 500 mm this is among the longest catalog strokes in the 200 mm bore group, so plan installation length and the larger air volume a long column demands before choosing it over the 250 mm and shorter siblings. The magnet is the only difference from the plain SILF200X500 code, and the F lock holds the rod at the front (rod-end) cover - pick SILB200X500S if the load must be held at the rear. Basic end mounting is fitted; FA front flange, FB rear flange and TC center trunnion versions, or the G (BSPP) port option, can be ordered against the same stroke.
Applications
Long conveyor stopper
Raise and lower a stop or gate over 500 mm of travel and use reed switches on the piston magnet to confirm the stopper is fully up before product is released.
Vertical lift with position check
On a lift column, sensor signals from the built-in magnet verify both ends of the 500 mm stroke, while the front lock holds the held position on air loss.
Slide end-position verification
Long transfer slides benefit from the magnet: barrel-mounted sensors report mid-stroke and end positions across the full 500 mm without external encoders.
FAQ
What are the key figures for the SILF200X500S in one place?
200 mm bore, 500 mm stroke, double acting with front-cover end lock, built-in magnet for position sensors, 40 mm rod with M36x2 thread, 3/4 inch PT ports, 0.15 to 1.0 MPa working (1.5 MPa proof), -20 to +70 C, 30 to 500 mm/s, adjustable air cushions, 21991 N push / 21112 N pull at 0.7 MPa.
Is the SILF200X500S still available as an SIL series part?
No - the SILF/SILB series is discontinued. The code is supplied as SAILF200X500S, the current replacement with the same suffix after the SAIL prefix, and all specifications on this page are those of the replacement unit you receive.
