Frictional locking devices come in various configurations, usually anywhere from someone to three pieces, More compact sizes usually are reserved for lower torque, less demanding operations. Devices that operate at large torques or in specifically demanding operations are often available in specialized configurations from various manufacturers. Engineers should check with documentation and also have good design calculations to choose frictional locking devices for his or her systems. Manufacturers usually supply the necessary equations to size locking devices. Always check with manufacturers with any questions and concerns.

Advantages such as these make friction locking devices applicable oftentimes. With their compatibility and simplicity, engineers often choose them for a variety of situations. But which situations are best suited for frictional locking devices and which are best to steer clear of? Generally engineers should steer clear of employing them in situations with high external centrifugal forces. These conditions could cause a drop in the pressure between the components and lead to slipping. Because there is often a tiny slit in frictional locking devices-to accommodate shafts of various diameters-these could cause imbalances in certain operating conditions, usually at bigger speeds. In this kind of applications, engineers can use slit-a smaller amount friction locking devices, which have stricter machining and program tolerances, or use another type of locking device.

No keys also means no be concerned over loose keyed elements at reduced torque ratings; loose keys can cause vibrations and accidental injuries, and damage devices. All that engineers require out from the system is the ability to put in the shaft into the locking machine, the frictional locking device in that case exerts radial pressure, locking the components in place. When compared to keyed connections, they can be backlash free with proper suit tolerances, they allow the ability to make modifications to the axial placement and angular timing in something, no impact between major and key-method occurs when reversing the machine because no keys can be found.

Frictional locking devices have the benefit that they do not require keying. That is, no need to correctly align keys and key-ways, and no need to fret if these will always be compatible when making systems. Indeed, for the reason that locking is completely performed by friction between the locking unit and the shaft, the machine can even cope with oversized and undersized shafts.
