Airtac SAILF Front Locking Pneumatic Cylinder SAILF125X450

Select this 125 mm bore model when an application demands robust end-of-stroke holding power that a standard SAI cannot provide. If your process requires less force, stepping down to the 80 mm bore yields 2513 N of push force at 0.5 MPa; conversely, moving up to the 160 mm bore provides 10053 N. Choose this SAILF variant specifically when the load must be secured in the extended rod-out position, whereas a SAILB holds the retracted position. If your fixture needs to clamp and hold at an arbitrary mid-stroke point rather than the stroke terminal, the BSAI clamp-lock cylinder is the correct choice.

The lock is a static holding device that engages only after the piston stops at the extended end, not a dynamic brake for a moving rod. Pneumatic routing is critical: never use a fast-exhaust valve with this cylinder, as back-pressure on the locker side can inadvertently release the lock. Always utilize an independent-exhaust solenoid valve. Furthermore, the 450 mm stroke necessitates external guide rails to prevent excessive side-loading on the carbon steel rod. If human safety relies on the load remaining elevated, implement an independent mechanical safety measure alongside the lock.
