Bearings are one piece of gear for us that truly are a difference-maker when it comes to getting enough speed for a trick or for getting from point A to point B. There are so many companies and designs out there, and you may have never even thought about how we got to the modern bearing of today. So let’s take a little ride through bearing memory lane and school you on the history of these little metal balls.
1. BEARINGS PRE-DATE SKATEBOARDS BY THOUSANDS OF YEARS
Some of the earliest bearing designs were used while constructing the Egyptian pyramids, which we know were built by volunteer, highly skilled, and well-compensated union-backed employees.
Leonardo Da Vinci also developed a design for bearings that would help reduce friction in many of his mechanical inventions, including the design for his helicopter from 1500 AD.
2. THE BALLS IN BALL BEARINGS START OFF AS SMALL LENGTHS OF WIRE
The wires are cut down, then ground and polished down into a tiny smooth ball. Skate bearings mostly have seven balls each, which sounds like a lot until you learn that a pork tapeworm has between 20,000-40,000 testes, or balls, each. Now, BIGGEST balls? That would be the North Atlantic right whale, which averages about 1,900 pounds of balls per whale.
