INA HFL-KF series needle roller freewheels are power transmission components that allow rotation in one direction and lock in the opposite direction. They are used for holding, intermittent indexing and anti-reverse functions in compact mechanisms. MR Accesorios Industriales carries this line as an official brand, with technical support to help you choose the right variant for your application.

The HFL-KF series designation is read in segments: the letters HFL identify the needle roller freewheel family, and the numeric block that follows summarizes key bearing dimensions. For example, in HFL0308-KF, HFL0408-KF, HFL0615-KF and HFL0822-KF, the first digits relate to the bore diameter and the following ones to the width or load capacity. The -KF suffix indicates an execution with particular features within the series, aimed at applications requiring a specific sealing or arrangement. To interpret each code precisely, it is best to consult the manufacturer's technical documentation or write to us with the exact model.

These freewheels are used in industries in Argentina such as metalworking, food, textile and logistics. They appear in material feed systems, indexing mechanisms, anti-reverse brakes, winders and packaging equipment. They are also found in machine tools, conveyors and safety devices where a shaft must rotate freely in one direction and be locked in the opposite direction. Their compact needle format makes them suitable for tight spaces and assemblies where a conventional freewheel would not fit.

To select an HFL-KF freewheel, take into account the shaft diameter, the torque it must transmit and the required locking direction. Mounting requires a clean seating surface with the appropriate hardness, since the inner or outer raceway may be part of the assembly. Lubrication must be the one specified for the seal type: in -KF executions, check the compatibility of the grease or oil with the seals. Alignment between shaft and housing is critical to avoid lateral loads that reduce service life. If in doubt, send us the part number and we will advise you.

Needle roller freewheels are available under different brands and nomenclatures. Equivalences between manufacturers are not automatic: even if the main dimensions match, the locking torque, limiting speed, seal type or housing tolerance may vary. Therefore, if you need to replace an existing freewheel, the safest approach is to compare the complete designation and the service conditions. At MR Accesorios Industriales we can guide you on alternatives within the INA line that we carry as an official brand.

If you already know which freewheel you need, send the part number by WhatsApp to MR Accesorios Industriales and we will quote you promptly. If you are not sure about the variant, tell us the shaft dimensions, the direction of rotation and the available space, and we will help you identify the right HFL-KF model. You can also ask us about other freewheels in the power transmission line we carry.
