What Are the Key Bearings and Features for Machine Tools?
Machine Tools. Machine Tool applications require bearings that are designed for rigid, high speed, high precision machine tool spindles. Machine tools are designed to cut or shape metals, ceramics, wood, and other materials into a desired form. Historical artifacts suggest machine tools have been used by humans for thousands of years.
FAG bearings distributor | Schaeffler Germany
FAG Bearings have been synonymous with high quality for over 120 years. In 1883, Friedrich Fischer designed a ball grinding machine in Schweinfurt, Germany that, for the first time, made it possible to produce absolutely round steel balls by grinding. The invention is regarded as the foundation for the entire rolling bearing industry.

Greases and Lubrication
As to how much to add, most motors are OVER greased. One or two "shots" from a grease gun is all (about 2 teaspoons). Once a year greasing is way more than most applications need. Example, for new motors, Baldor recommends greasing motor bearings every 5,000 hours of operation (3600rpm) or 12,000 hours (1800rpm).
