Wheel Bearings

BACKGROUND FROM THE HUB


The Wheel Bearing: A Brief Summary of a Long History

During the period of the pharaohs, Egyptians introduced the concept of bearings by using round timbers to move heavy blocks.

As the bearing was developed and improved over centuries, it inspired profound advances in transportation, construction, and manufacturing. Its contribution to civilization: dramatically reducing the effort required to move large or heavy objects over surfaces.

The Wheel Bearing’s Role in Vehicles Today

In vehicles, a bearing is an important part of the wheel assembly. Its function is to help reduce friction, provide load support, and guide these moving parts:

  • Wheel
  • Pivot
  • Shaft

Vehicle Parts Move in a Variety of Ways:

  • Rotate
  • Oscillate
  • Slide

The Wheel Hub Bearing Unit is Vital to a Vehicle Because it:

  • Enables wheels to turn freely
  • Contributes to the safety and handling of a vehicle during driving
  • Includes the wheel speed sensor that controls the Anti-Lock Braking System (ABS)
  • Is critical to the Traction Control System (TCS)
  • BCA OE quality replacement parts are your smart, reliable solutions for Gen 1, Gen2, and Gen 3 installations

The Basics of Wheel Bearings and Loose Bearings

Application-Specific Engineering Design to ensure the correct fit, function and high performance of the wheel bearing. BCA® supplies premium replacement bearings that meet or exceed the OE specifications.

Premium Quality Materials are used for forged steel rings, seals, precision cages, rolling elements and premium grease, to ensure that our customers receive a robust, durable product.

  • The Correct Steel for the Correct Part:  For wheel bearings, BCA utilizes Forged Steel in the inner and outer rings that meets our stringent steel quality specifications to optimize bearing life. For taper bearings, BCA utilizes Case Carburized Steel for heavy duty shock loads & longer life. BCA is recognized as the leading manufacturer of case carburized taper bearings.
  • Seals are customized for each BCA hub based on application-specific materials & design requirements to minimize the chance of contamination and maximize bearing life.
  • Precision Cage on BCA bearings are designed to keep the rolling elements of the bearing spaced correctly. The cages undergo design verification and production validation testing to ensure high quality.

Pre-Lubrication of all BCA wheel bearings with premium grease for your convenience. This is a major advantage so you do not have to worry about grease or seal application.

Most of these Vehicles Use Wheel Hub Bearing Units:

  • Cars
  • Passenger vehicles
  • Light Trucks
  • Heavy trucks
