Frictional locking devices can be found in various configurations, usually from one to three pieces, Small sizes are usually reserved for lower torque, less demanding operations. Systems that operate at great torques or in specifically demanding operations are often obtainable in specialty configurations from various suppliers. Engineers should consult documentation and have good style calculations to select frictional locking equipment for his or her systems. Manufacturers usually supply the required equations to size locking devices. Always check with manufacturers with any problems and concerns.
Advantages such as these make friction locking products applicable in many cases. With their compatibility and ease of use, engineers often choose them for a number of situations. But which conditions are best suited for frictional locking products and which are best to steer clear of? Generally engineers should prevent employing them in situations with high external centrifugal forces. These situations can cause a drop in the pressure between your components and cause slipping. Because there is normally a small slit in frictional locking devices-to accommodate shafts of varying diameters-these could cause imbalances in certain operating conditions, generally at bigger speeds. In this sort of applications, engineers can use slit-a smaller amount friction locking devices, that have stricter machining and request tolerances, 
or use another type of locking device.
No keys also means no stress over loose keyed components at reduced torque rankings; loose keys could cause vibrations and accidents, and damage gear. All that engineers require out from the system is the ability to put in the shaft in to the locking machine, the frictional locking unit after that exerts radial pressure, locking the components in place. In comparison with keyed connections, they can be backlash free with proper suit tolerances, they permit the ability to make adjustments to the axial location and angular timing in a system, no impact between crucial and key-approach occurs when reversing the machine because no keys are present.
Frictional locking devices have the benefit that they don’t require keying. That is, no need to effectively align keys and key-ways, and no need to be anxious if these will always be compatible when making systems. Indeed, for the reason that locking is completely performed by friction between your locking unit and the shaft, the system can even deal with oversized and undersized shafts.
