Rolling bearings. Rolling bearings support and guide rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. They provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear.
The grease provided in shielded electric motor ball bearings remains effective to approximately 200-210°F. For electric motors used in high-temperature environments, special consideration should be given to the bearing lubricant. Overheating in electric motor bearings is generally lubricant-related.
Tumbling mills have been widely implemented in many industrial sectors for the grinding of bulk materials. They have been used for decades in the production of fines and in the final stages of ore comminution, where optimal levels for the enrichment particles’ sizes are obtained. Even though these ubiquitous machines of relatively simple construction have been subjected …

The Ballbar test will measure any deviation the machine makes from a perfect circle, recording data as the two axes work together. Errors such as backlash, level/squareness, servo mismatch, reversal spikes, vibration, stick slip and other problems can be determined. Users can be useful in determining what feedrate delivers the best accuracy by ...
