What is a built-in freewheel?
A built-in freewheel is a specialized mechanical component designed to transmit torque in one direction while allowing free motion in the opposite direction. It is essential for applications where rotation is required to be transmitted only during certain conditions, effectively preventing backdriving. For optimal performance, built-in freewheels must be integrated within a housing that provides robust bearing support, ensuring stability and longevity of the mechanism.

 

When to use a built-in freewheel
Built-in freewheels are suitable for scenarios that demand low to medium torque and speeds. They are commonly employed in conveyor systems, printing machinery, and various types of light to medium industrial equipment. The type of support for these freewheels is non-supported, which means they rely on external components for radial and axial loads. This configuration is ideal for applications where space constraints necessitate a compact design and where the equipment can provide the necessary external support structure. Choosing a built-in freewheel ensures a streamlined integration into the system, providing a reliable solution for unidirectional torque transmission.
