Hub bearing units must meet the increasing demand for light weight, energy saving, and modularity. In addition, the anti lock braking system (ABS) is becoming more and more popular in order to ensure the safety and reliability of the braking. Therefore, the market demand for sensor built in hub bearing units is also increasing. NSK with first-class bearings manufacturers original high technology and strict your presence test data, the successful development of a small, lightweight, ABS built-in sensor hub bearing unit with high quality. 
  
 traditional type (using two sets of single row bearings)   effective load center between the long distance (driven wheel)   inconvenience to preload. The 
   installation process is complex. 
   needs filling grease. 
   generation I wheel bearing unit  , compared with the traditional type,   preload, simple and reliable. 
   installation is convenient. 
   does not need gaskets. 
   does not require make-up grease. 
   compact structure. 
   built in high performance sealing ring. Compared with the I generation wheel bearing units, the 
   II generation wheel bearing unit   is simpler and more reliable to apply   preload. 
   installation is convenient. The 
   does not need to press into the steering knuckle. 
   such as the outer ring rotation, you can also install the sensor rotor. Compared with the II generation wheel bearing unit, the 
   generation III wheel bearing unit   can exert the best preload  . 
   installation is convenient. 
   high stiffness. 
   easy to install anti lock braking system (ABS) sensors.                                |
