|
|
Locking devices for internal applications fit between the component to be locked and the shaft. The component being locked has a thru bore or a counter bore for the locking device. Locking devices for external applications fit over the hub of the component to be locked. The component can have one hub projection or two, symmetrical hub projections.

Your choices are...
|
|
|
| |
Internal (Thru Bore)
|
|
The locking device can be mounted in a thru bore in the component (does not require a pre-centering bore). The locking device fits between the component and the shaft. As an axial load is applied by the locking device, a radial load is generated onto the shaft and component hub bore providing a frictional locking connection.
|
| |
Internal (Counter Bore)
|
|
The locking device requires a pre-centering counter (blind) bore in the component. The locking device fits between the component counter bore and the shaft. As an axial load is applied by the locking device, a radial load is generated in the shaft and the component hub bore providing a frictional locking connection.
|
| |
External
|
|
The component has a hub projection. The component fits over the shaft and the locking device fits over the component hub projection. The locking device exerts a radial force that transmits through the hub and onto the shaft, frictionally locking the component in place.
|
| |
External (Split)
|
|
The component has symmetrical hub projections and the locking device has two equal sections. The component fits over the shaft and the locking device fits over the component hub projections. The two halves of the locking device clamp together via bolts that run through the component being clamped. When tightened, the locking device exerts a radial force that transmits through the hub and onto the shaft, frictionally locking the component in place.
