Airtac SAILF Front Locking Pneumatic Cylinder SAILF160X400S

Choose this 160mm bore cylinder when an application demands high thrust, such as the 14074N push force at 0.7 MPa, alongside guaranteed load holding at the extended position. If your system requires slightly less force, stepping down to a 125mm bore yields 8590N of push at 0.7 MPa. Conversely, moving up to a 200mm bore provides 21991N of push at 0.7 MPa for heavier mechanisms. Select the SAILF front-locker variant when the machinery must hold the rod securely in the extended out position during a power loss. If the mechanism instead needs to hold the load retracted, the SAILB back-locker version is required. For applications requiring mid-stroke clamping rather than end-of-stroke holding, the BSAI clamp-lock cylinder is the correct alternative.

When integrating this cylinder, strictly avoid using a fast-exhaust valve, as back-pressure on the locker side can unintentionally release the lock; always use an independent-exhaust solenoid valve. The lock engages only at the stroke terminal on the locker side, meaning it will not clamp the rod at an arbitrary mid-stroke point. If human safety depends on the load remaining extended, add an independent safety measure as well. At 400mm stroke, this unit is within the 1500mm maximum standard stroke for this bore, but you should still utilize appropriate side-load guides to prevent rod deflection. Replacement matches require the exact 160mm bore, 400mm stroke, front locker position, PT port, and the -S magnet.
