About the Airtac SILF Front Locking Air Cylinder SILF80X300
Within the SILF80 line, SILF80X300 is the 300 mm stroke entry: an ISO 15552 body with an 80 mm bore, a mechanical lock at the front cover and plain basic mounting. AirTAC has discontinued the SILF/SILB series, so the code you order ships as SAILF80X300, and every figure on this page describes that delivered SAIL unit.
With 300 mm of travel the rod sweeps a long column, so cushioning matters: adjustable air cushions tame the load at both ends across the 30 to 800 mm/s speed band. Output at the M20x1.5 rod thread is 2513 N push and 2268 N pull at 0.5 MPa, rising to 3519 N and 3175 N at 0.7 MPa. Ports are 3/8" PT, the air supply must be filtered by a 40 um element, and the front lock frees itself automatically on air or by hand lever.

How to choose
Choose this code when 300 mm is the travel your machine needs; a longer stroke only adds length, weight and air consumption, never force. Siblings: SILF80X250 for a shorter throw and SILF80X400 for a longer one; SILB80X300 relocates the lock to the rear cover, SILF80X300S adds the built-in magnet missing from this code, SILF80X300G converts the ports to G (BSPP), and CA, TC or FTC suffixes swap basic mounting for clevis or trunnion.
Applications
Conveyor reject pusher
A 300 mm stroke reaches across a belt lane; the front lock holds the pusher extended during a line stop even with both PT ports exhausted.
Lift-and-lock positioning table
A 300 mm lift with a front lock catches the table at the rod end if supply pressure drops mid-cycle, and the hand lever lets an operator lower it safely for service.
Test rig stroke control
For rigs needing a controlled 300 mm pull, the 2268 N pull force at 0.5 MPa and the M20x1.5 thread accept standard load cells and fixture hardware.
FAQ
What are the key figures of the SILF80X300?
Supplied as SAILF80X300: 80 mm bore, 300 mm stroke, double acting with front-cover end lock, 3/8" PT ports, 25 mm rod, M20x1.5 thread. Pressure 0.15 to 1.0 MPa (proof 1.5 MPa), temperature -20 to +70 C, speed 30 to 800 mm/s, adjustable air cushions. Push 2513 N at 0.5 MPa and 3519 N at 0.7 MPa; pull 2268 N and 3175 N.
Can I sense piston position on the SILF80X300?
Not with this code as ordered: the sensor field in the ordering code is blank, so no magnet is built in. If your controls need reed or Hall sensing, order SILF80X300S instead, which carries the built-in magnet for position sensors while keeping the same 300 mm stroke, front lock and all other options.
