Our ball bearings should have a good, long life under optimal conditions. Depending on the application, bearing failure can be very costly and possibly cause more harm. Learning how to identify bearings that need to be replaced is a skill worth developing. Some typical signs that your bearings need to be replaced are:

• Your application is running excessively hot
• Your application is running excessively noisy
• There is excess slop or play in the bearing
• Turning the bearing results in a gritty feel rather than a smooth feel

When bearings sit idle for a long time, they must be protected from any and all moisture. This is a common problem when storing small RC engines. If any moisture has gotten to the bearings, they will need to be replaced before using the engine again. In our next issue of the Boca Bearings Tips & Advice Newsletter we will talk about the best way to Remove Your Engine Bearings.
 - Boca Bearing Product Highlight -  
Ceramics are the new Holy Grail! They are lighter, smoother, harder, corrosion resistant, and electrically resistant. These fundamental characteristics allow for a wide range of performance enhancements in bearings. Ceramic dissipates heat quickly, reducing friction and wear while maintaining a precision smooth surface. Today's leading edge ceramics are made with Silicon Nitride (Si3N4) and have characteristics similar to the heat absorbing, highly resilient tiles on the Space Shuttle.

Boca Bearings is proud to introduce their new Ceramic Lightning Series bearings. Ceramics are the sercret weapon of champions for RC enthusiasts, Bicycling fanatics, In-Line Skaters and many others. The Lightning Series are available in standard, rubber sealed and ultra sealed configurations.
