A variety of factors including bearing geometry affect miniature ball bearings' speed. Bearing rings are ground to very tight tolerances and polished to a smooth and shiny finish. Bearing steel is high quality with small, evenly spaced carbides. Large carbides and inclusions reduce the quality of the steel and create “tear outs” and “comet tails” in the raceway. This not only slows the bearing but shortens the life of the bearing. Similarly, people must maintain superior ball quality for optimal performance.
SUNBEARING uses only the most reputable steel and ball vendors to ensure reliable, repeatable quality in all our domestically produced miniature ball bearings. Produce the bearing retainer/cage from high-quality materials and piloted in such a way, that it does not drag on any of the bearing components. Retainer drag will not only slow the bearing rotation but will result in premature failure of the bearing assembly. Proper lubrication will enhance bearing performance and extend bearing life. Too much or too little lube or the wrong viscosity of bearing lubricant will also impair bearing performance.
Some limiting factors include component quality, lubrication density, retainer material, and design. The upper-level assembly of the bearing can also limit the bearing speed. Atmospheric conditions such as contamination, ambient or fluctuating temperatures, and moisture all impact the bearings' speed capabilities. It is important to discuss the bearing’s operating environment, to make sure that you can consider vacuum conditions, salt baths, and other environmental factors for optimum performance.
Special coatings, various ball and retainer materials and a wide range of bearing lubricants are available to satisfy specific environmental conditions, speed, temperature, and other factors.
Bearings are an essential component in many products and assemblies. The bearing allows the shaft to turn and control speed and vibration in an assembly. Getting the product to market expeditiously is crucial to any project plan. Therefore, People design a bearing from standard envelope dimensions with minimal special features that will help contain project costs and reduce component lead times.
