Ball vs. Sleeve A Comparison in Bearing Performance
exceeded 70° C, ball bearing fans ran for 45,000 hours, while sleeve bearing fans became inoperable. Yet, when the aient temperatures were relatively low, sleeve bearing fans lasted as long as ball bearing fans. Therefore, if an appliion generates high levels of heat, an engineer may want to use a ball bearing fan.

» Grease life in lubried-for-life deep groove ball bearings
May 26, 2004· The following examples show that a higher GPF is not always an improvement. In a sealed deep groove ball bearing operating at. n x d m =300,000 and 55°C, a grease with GPF=1 is the best solution, giving L 10 =30,000 hours. For GPF=2 the estimated life is the same, whereas a grease with GPF=4 is not recommended, due to a shorter life.

Ball Bearings Selection Guide: Types, Features
Ball bearings are used to provide smooth, low friction motion in rotary appliions. Ball bearings are able to provide high performance and long lifetime in order to transfer the load from the balls to the inner races. The balls have minimal contact with the inner and outer races due to their spherical shape and this allows them to spin smoothly.
