Hub unit 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.
Conventional TypeLong distance between effective load centers (for non-driven wheels);
Compared to conventional type;
Compared to HUB I;
Compared to HUB II;
An angular passive sensor is located in the radial space between the swaged shaft end and sensor cover.
The ABS sensor is located between the rows with a very small air gap.
A multipole magnetic encoder for active sensor is used for ABS attached to the HUB unit bearings.
Integration of ABS Active Sensor and Bearing.
Double-row angular contact ball bearing with integral high performance seal Easier preload setting.
Double-row tapered roller bearing with integral high performance seal. Suitable for heavy-duty vehicles.
Outer ring rotating hub unit bearing with outer flange for mounting the wheel.
Inner ring rotating hub unit bearing with outer flange for mounting onto the knuckle.
Inner ring rotating tapered roller hub unit bearing with integral flange for mounting onto knuckle. Suitable for heavy-duty vehicles.
Double-row angular contact ball bearing with integral inner and outer mounting flange Easier mounting because of preset preload.
Double-row angular contact ball bearing with integral inner and outer mounting flange. Easy incorporation of ABS sensor.
Hub unit bearing achieves lightweight by incorporating a unique design specifically for minivehicles.
Achieved optimal design of outside hub flange using FEM to maintain stress concentrations within the permissible range, and for further weight reduction.
