What is the difference between Ball Guide Bearing and Slide Bearing,Where are they used?
 |  |
The rolling bearing has higher running accuracy, Ball bearings can bear radial and axial loads at the same time, The friction coefficient of ball bearings is smaller than that of plain bearings,It can save the expensive nonferrous metals needed for the manufacture of sliding bearings; But ball bearings are particularly sensitive to foreign bodies such as metal chips. The service time of ball bearings is shorter than that of sliding bearings. The load bearing capacity of ball bearings is much smaller than that of sliding bearings of the same volume.Therefore, in the occasion of bearing large load and requirements of small radial size, compact structure requirements (such as internal combustion engine crankshaft bearings, rolling mill roller bearings), the use of sliding bearings;The vibration and noise of ball bearings are large. Therefore, when the precision is very high and the vibration is not allowed, the general ball bearings are difficult to meet the requirements, and the sliding bearings are often chosen.
