RINGSPANN FRHD series freewheels are power transmission components that allow rotation in one direction and lock the reverse movement. They are used as backstops or anti-reverse devices in equipment where shaft back-rotation must be prevented, for example on inclined belt conveyors, elevators or pumping systems. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, with technical advice to choose the model according to the application.
The FRHD series designation is read by its acronym and the number that follows. In the examples FRHD 700, FRHD 775, FRHD 800, FRHD 900 and FRHD 950, the number identifies the size of the component within the series. The higher the number, the greater the capacity of the freewheel. To select the correct model, the part number must be cross-referenced with the working conditions: shaft diameter, backstop torque and rotation speed. If you have the part number, write to us and we will send you the technical information.
These freewheels are used in continuous process industries where equipment back-rotation can cause damage or material accumulation. They are commonly found in inclined belt conveyors, bucket elevators, mills, mixers and centrifugal pumps. In Argentina they are used in food, cement, mining, aggregate processing plants and material handling systems. Their function is to hold the load when the motor stops, preventing the equipment from rotating in the opposite direction.
To select an FRHD freewheel, consider the required backstop torque, the shaft rotation speed and the type of mounting. It is important to verify the alignment between the shaft and the component, and to ensure adequate lubrication according to the environment. In dusty or humid environments, additional protections should be evaluated. Mounting must follow the manufacturer's instructions to guarantee correct operation and the service life of the component.
RINGSPANN freewheels can be interchanged with equivalent components from other brands, but the equivalence is not automatic: mounting dimensions, backstop torque and permissible speed must be compared. It is not enough for the part number to be similar. Therefore, before replacing a freewheel, it is advisable to check the technical data sheet of the original equipment and compare the data with the supplier. MR Accesorios Industriales can help you with that comparison.
