The Power of Powder – Lubricant Boosts Bearing Speed 50 Percent
Kaur, R.G. and Heshmat, H. “The Power of Powder – Lubricant Boosts Bearing Speed 50 Percent,” (May 2001) Lubes’n Greases, Volume 7 (5), pp. 50-54.
A highly sophisticated and unique journal bearing technology, only recently developed, has been demonstrated to operate up to 30,000 rpm, or 3 million DN. That’s 50 percent faster than today’s conventional journal bearings, which rarely push beyond 2 million DN. (DN is an expression of rotating speed, calculated by multiplying the rotating shafts diameter in millimeters by its speed in rpm. So a 100 mm shaft rotating at 30,000 rpm would be moving at 3 million DN.)
