3 Types Of Porsche Bearing Lubricants And How To Use Them

Lubricating your Porsche bearings play a crucial role in making sure that these parts will function properly. Once lubricated, friction is lessened as well. This will then eventually prevent wear and tear for the bearings. Take note that depending on your car model, there are different types of Porsche bearing lubricants too. Get to know these types better and how you must use them.


For your car's bearings, both synthetic and petroleum-based oils are available for use. Synthetic oils include fluorinated compounds, PAO's, silicone, and diesters among others. Using oil to lubricate bearings will allow the car to start and run smoothly while also exhibiting higher speed capability. The service life of oils in bearings can be less than grease though. In order to use them properly, you need to make use of oil recirculation systems that are designed to work on specific equipment and machinery that manufacture bearings.


Grease is a type of lubricant that uses a base oil combined with a thickener. The thickener is basically made from metal soaps such as sodium, aluminum, lithium, and calcium. Metal soaps are mixed with organic as well as inorganic compounds. In some cases, additives are mixed with the grease in order to help improve its performance. Among these additives are fillers, anti-wear, and anti-corrosion fortifiers. You must select grease only after you have checked the temperature range, stiffness, and base oil viscosity. Greases are typically used in bearings that are given NLGI grade 2.

Solid Films

Also known as non-fluid coatings, solid films are typically applied to surfaces prone to friction in order to prevent bearing wear and tear. They are recommended for use in extreme conditions where grease and oil cannot be used. Solid films are often the last resort though.

Lubricant Effects on the Car

Lubricant bearings may have an impact on the car's maximum operating speed and torque whether during startup or while the car is running. For miniature bearing, lubricants can help minimize noise level. It is recommended that miniature as well as instrumental bearings must only use filtered oils and greases.

How Lubricants are Used

Lubricants are used depending on their types. In the case of the grease, this can be applied on the bearing with the use of a special lubricating equipment. This equipment contains a head that can deposit the grease between the balls. Once the bearing rotates, the grease is distributed. The grease is applied to the bearings in a clean room environment.

Oil, like grease, also uses a special equipment for application of the lubricant over the bearings. In case the application is done in torque sensitive applications, centrifuging will help remove any excess oil. Removal of excess oil is normal in the process because the amount of lubricant used is not specified at all times.

If you want to make sure your bearings like knuckle bearings and miniature bearings are working properly all the time, you simply need to get a lubricant recommended for the bearing in your car. Remember to check manufacturer specifications before lubricating this part of the vehicle.
