high speed ball bearing numbering system
Magnetic Bearings - Ultra-high-speed electrical drive systems
Therefore, magnetic bearings have only been successful up to rotational speeds of about 120,000 rpm. To overcome these rotational speed limits, Celeroton has researched a new magnetic bearing concept. The new bearing enables rotational speeds of 500,000 rpm and more, which represents the world record for a magnetically levitated drive system.

Choosing a High-speed Grease - Machinery Lubriion
The NLGI nuer is a measure of the grease’s consistency. The higher the NLGI nuer, the thicker the overall consistency. The scale ranges from 000 (fluid like) to 6 (solid block). When it comes to high-speed greases for rolling-element bearings, the NLGI grade tends to go up while the base oil viscosity goes down.
