Lighten the load on your high-speed applications with this ball bearing from SKF. It handles axial and radial loads in both directions to streamline the performance of your machinery. Because the unit's designed to generate low friction, it's energy-efficient and runs quietly. Heat generation is also reduced, giving the unit a reliably long lifespan. The strong sheet metal cage is tough enough to handle the demands of heavy-duty environments.

• Radial internal clearance minimises play and ensures stability

• Domestic appliances

It has a dynamic load rating of 4.36kN, meaning it can handle heavy loads and tougher jobs.

This depends on where and how they're used. Look for signs of misalignment such as wobbling, as well as unusual noises like hums and clicks, as indicators that it's time for replacement.
