Can I Use WD-40 For My Skate Bearings?

Bearing Fundamentals, Lubrication, Myths and Truths

Lets have a serious talk about WD-40 as a skate bearing lubricant. If you don’t have time to get serious, the TL:DR is that we do not recommend using the WD-40 Multi-Use Product in your skate bearings unless you are in a pinch and it’s your only hope.

First let’s start with what the WD-40 brand name is said to mean. From the history of the WD-40 company they say it was a Water Displacement product perfected on the 40th try. The original WD-40 Multi-Use Product was then used by aerospace contractor Convair to protect the outer skin of the Atlas Missile from rust and corrosion. Clearly the chemical mixture has its credentials in protection of metals like those found in our skate bearings.
