What is a freewheel?

A freewheel, also known as a one-way clutch, sprag clutch, or overrunning clutch, is a mechanical device that allows rotational motion in one direction, while preventing motion in the opposite direction. Sprag clutches are a type of freewheel that use wedging elements, often referred to as sprags, to lock and allow rotation in one direction only. Overrunning clutches, on the other hand, are designed to free the output shaft when the input speed is lower, thus preventing backdriving in systems like starter motors. This mechanism is essential in various applications where it is crucial to transmit power in one direction only, such as in conveyor systems, bicycles, or certain types of machinery. Our range of freewheels, sprag, and overrunning clutches is meticulously engineered to ensure reliable performance and durability, making them an ideal solution for your power transmission needs.

 

Choosing the right freewheel:

At BJ-Gear A/S, we understand the significance of selecting the right freewheel to meet the demands of your machinery and operations.

  • Identify application requirements: Begin by evaluating the specific operational requirements of your system, including torque, speed, and load conditions. Understanding these parameters will help determine the appropriate type and size of the freewheel needed.
  • Consider environmental factors: Take into account the environmental conditions in which the freewheel will operate. Factors such as temperature variations, exposure to moisture, and the presence of contaminants can impact the choice of the ovmost suitable freewheel for your application.
  • Assess installation compatibility: Assess the compatibility of the freewheel with your existing system. Consider factors such as available mounting space, shaft dimensions, and any additional components required for seamless integration.
  • Evaluate maintenance needs: Evaluate the maintenance requirements of the freewheel options under consideration. Opt for a freewheel with a design that aligns with your maintenance capabilities and schedule, ensuring smooth operation and longevity with minimal upkeep.

 

By carefully considering these factors, you can make an informed decision when choosing the right freewheel, ensuring reliable and efficient performance tailored to your specific application requirements.
