Wheel Hub Unit 513121
Description
The 513121 hub unit has a splined shaft that provides a secure and stable connection to the wheel. This spindle helps support the ball bearings and serves as a seat for the hub unit's flange and seals. In turn, the flange is the mounting point for the bolts that secure the hub unit to the vehicle's suspension system. These bolts secure the hub unit in place, providing maximum stability and performance.
In addition to the spindle, flange, ball bearings and bolts, the 513121 hub unit features high quality seals that keep the hub assembly free of dust, dirt and debris. Seals protect the unit from contamination, ensuring smooth operation and longer life of the ball bearings.
The 513121 hub unit is also equipped with an integrated sensor that collects essential data from the wheel while monitoring wheel movement. The sensor is an essential part of modern car electronics, providing critical information to the vehicle's on-board computer system, enabling drivers to make informed decisions about how they drive.
When it comes to durability, the 513121 hub unit is designed to withstand extreme weather conditions and harsh driving environments. The ball bearings are manufactured to a high standard and the seals ensure that no contamination enters the unit. All components are designed for longevity and consistent, reliable performance.
513121 is the 3rd generation hub assembly in structure of double row angular contact balls, which is used on driven shaft of automotive wheel, and it consists of splined spindle, flange, balls, seals, sensor & bolts.
