Bearings can be measured in inches or metrically in millimeters. There are three main dimensions along which bearings are measured. These are the bore, or inner diameter, the outer diameter, and the width. There are standard designations given to ceramic ball bearings to indicate their bore size. For the standard series bearing, a 00 designation indicates a 10mm bore, 01 indicates a 12 mm bore, 02 indicates a 15 mm bore, 03 indicates a 17 mm bore, and 04 indicates a 20 mm bore. For larger ball bearings, the measure of a standard series bore in millimeters is five times the numeric designation.

ball bearings are of the highest quality and are designed to last and keep your applications running for a long time. However, as with any machine parts, proper care and handling is a critical factor in making your bearings last. The best way to protect your small bearings is probably the use of seals and shields for your ceramic ball bearings. These features are specifically designed to prevent contamination. That being said, some dirt or other particles may still find their way into the bearing, which is why it is important to take other steps to protect your bearings. This means that when you are putting your bearings into your application, you should take extra effort to avoid any kind of contamination. Keep the room where you will be handling the ina bearings dry and clean, and do not take the bearings out of their packaging until you are ready to use them. 

If you drop a bearing, discard it. In addition to the fact that it may immediately accumulate damaging particles, there may be damage to the bearing which is not apparent to the naked eye. This damage may interfere with your application's efficiency or, at the very least, cause the application to generate a great deal more noise than desired. Also, when applying lubricant to your ball bearings, make sure that the lubricant is free from contaminants and refrain from using applicators like cotton swabs that could themselves contaminate the bearings.

Ceramic ball fag bearings are machinery components, which comprise an outer ring, inner ring, balls, retainers, shields and snap rings. Miniature and small-sized ball bearing mean ball bearing, up to 30mm in external diameter. Essential to high-precision rotary components, ball bearings determine rotational accuracy

Loose ball bearings are generally utilized to maintain space contained in the moving parts of some sort of rotating object, for case a wheel or gear. They're typically found within bicycle and car tires. The best place to buy for ball bearings is through the Internet, in which a broad various products are made available.

Use a spray of degreaser to shift the worst of the grime, then get to work on the bearings with a lint-free rag. Be careful to avoid popping the individual [ceramic ball bearings] out of the cage — they’re difficult to replace, especially without damaging the cage. As with cartridge bearings, brighter is better with ball bearings. If they look tired, they probably ought to go.
