NSK wheel bearings | Hub Unit Bearings

NSK wheel bearings have to meet increasingly strict requirements that demand lighter weight, greater promotion of fuel efficiency, and enhanced module production systems. Along with the widespread adoption of antilock braking systems (ABS) to ensure stable maneuverability during braking, there is a growing need for our hub unit bearings with a built-in sensor. NSK guarantees high quality of all of our products by repeated, rigorous bench testing and other checks that take full advantage of our cutting-edge technology, which only the top-bearing maker can offer. NSK offers compact and lightweight hub unit bearings with built-in ABS sensors.
