💡 How do one-way clutches prevent reverse rotation in power failure situations?
One-way clutches are super useful in vertical or inclined drive systems:

• They allow motion in only one direction, ideal for conveyors and lifts

• When power cuts off, gravity can reverse load direction; the clutch locks it in place

• They’re key in applications like escalators, printing presses, and gearboxes

• The keyway version provides direct torque locking between housing and clutch

Also called backstop clutches or overrunning clutches, perfect where reverse motion is not an option

When gravity strikes, make sure your system doesn’t backslide, this GFRN12 clutch has your back!
