BCA Bearings: Lubrication

How Does Lubrication Impact Bearing Functionality?

Contaminants such as water, salt and organic debris can cause wheel bearings to corrode and fail over time.

Lubrication is essential for the proper function of bearings because it reduces friction, which can cause damage or failure of the bearing. Lubrication also protects against corrosion and contaminants that can damage bearings and other wheel-end components. In the correct applications, lubricants extend the useful life of bearings to their optimum range.

Reduction Of Friction

The primary role of lubrication is to reduce friction between bearing components and adjacent components such as the spindle or axle. The heat generated by friction can cause bearings to deteriorate in a number of ways, including the destruction of seals, balls or raceways, depending on the type of bearing in your vehicle. A lack of lubrication can cause excessive friction, leading to wheel bearing failure and leaving a vehicle stranded on the side of the road.

Prevention Of Corrosion

Contaminants such as water, salt and organic debris can cause wheel bearings to corrode and fail over time. Lubrication serves as a vital barrier of protection against these contaminants, keeping the integrity of bearing intact. If bearing seals become loose, punctured, or otherwise damaged by debris, seeping lubricant can allow contaminants into the bearing and cause failure. It is important to inspect bearings and seals regularly to prevent untimely corrosion-based failures.

Stabilization Of Bearing Structures

Because of the critical role they play in wheel rotation, as well as the attachment of wheels to the vehicle, the structural integrity of wheel bearings is of paramount importance to the safe operation of a vehicle. Bearing lubricants can help bearings endure different loads and act as a stabilizing agent for bearing structures. The stabilizing effect of lubricants differs depending on whether grease, oil, or synthetic lubricants are used. You can count on bearing lubricants to help reinforce the overall functionality and reliability of bearings.

Lubrication is one of the most important factors impacting the operation and longevity of wheel bearings, which is why it is important to inspect and monitor bearing function on a regular basis. Without effective lubrication, drivers are being setup for potential breakdowns.

Adjusting Parking Brakes

You should never estimate when it comes to parking brake adjustments.

The parking or emergency brake has to perform two distinct jobs. First, it must be able to hold the vehicle on an incline. Second, it must be able to stop a vehicle under a specific distance if the hydraulic brakes have failed. These standards are set by the Department of Transportation (DOT), and the kicker is these standards must be met with the force applied by a little old lady. But, over time, the cables can stretch and the friction materials change their length and thickness, which is why adjustments to the system are required.
