Basic Advantages of Oilless Bearings

Basic Advantages of Oilless Bearings and Where to Get Them
In the industrial world, there are various types of bearings to choose from. The application or machinery that you are running, will dictate what bearing you purchase. Oilless bearings are manufactured from a material that incorporates its own lubrication in the form of powdered graphite. These types of bearings are also known as self-lubricating bearings. As a result, there is no oil or external lubricant required for these bearings to operate at their best.
