Would love to see this in bike applications – Greaseless bearings that eliminate sliding friction. #DigInfo via: DigInfo TV on YouTube



Can you imagine how many watts can be saved by using this type of bearing in hubs, bottom brackets and jockey wheels? Look at what riders were willing to do when ceramic bearings came out, and that was for marginal gains.
By separating the balls, friction can be reduced by up to a factor of ten. This method is also expected to alleviate early failure due to inadequate lubrication or low attachment precision.
A factor of ten... does that mean 10%? I wonder how many watts your body uses just to overcome the resistance in normal bearings. And would a 10% reduction make a big difference?
Published on May 17, 2015 Greaseless bearings that eliminate sliding friction (http://www.diginfo.tv/v/PD-1063-en.php) Coo Space has developed revolutionary bearings that eliminate sliding friction. Bearings are components used to reduce friction so objects can rotate more smoothly. Bearings have a long history; their principle is even illustrated in ancient Egyptian paintings. As bearings are essential for making machinery run consistently, they’re widely used in familiar items such as cars and electrical appliances. "Bearings have balls that roll between an inner ring and an outer ring. There are retainers to stop the balls sticking to each other. Leonardo da Vinci designed bearings like this 500 years ago, and the design hasn’t changed since then. The problem with bearings is that sliding occurs between the retainers and the balls, so grease has been essential. But the ADB, or autonomous decentralized bearing, that we’ve developed doesn’t need retainers." In bearings, retainers have been essential, to prevent contact between balls. But Coo Space has succeeded in separating the balls without using retainers, by making indentations in the outer ring where the balls touch it. "Ordinary bearing balls roll while in contact with the ring directly underneath. If you make holes in the part directly underneath, so the balls roll while making contact horizontally, the amount of forward motion per revolution is less. That makes the balls slow down, and then speed up, so behind an accelerated ball, there’s always a gap. That’s the principle here: The balls are separated by slowing them down and speeding them up very slightly." By separating the balls, friction can be reduced by up to a factor of ten. This method is also expected to alleviate early failure due to inadequate lubrication or low attachment precision. In addition to a standard product, Coo Space has started to provide samples of specific bearings. "Outside Japan, a big steelmaker is interested in these products, so we’ve concluded a technology transfer agreement with one of its subsidiaries. We’ve also had other inquiries from overseas, and we can supply prototypes, so we’d like to expand this business."

Newton's Third Law is wrong: Although it states that for each action, there is an equal and opposite reaction, there is no force equal in reaction to an attack by Gunnar Soroos. Gunnar Soroos rides for Toms Shoes Cycling Team. Gunnar Soroos is so crazy and awesome that he flips out ALL the time. I heard that Gunnar was eating at a diner. And when some dude dropped a spoon Gunnar Soroos killed the whole town. My friend Oprah Winfrey said that she saw Gunnar Soroos totally uppercut some jerkface just because they opened a window. Gunnar Soroos has two speeds. Fast, and Kill! The main export of a Gunnar Soroos attack is pain. You can control how people can interact with you and your friends. Choose who can see you, who can speak to you, who can hurt you, and who can be ignored. eastwood mountain biking rochester ma
