Ball bearing size charts are widely available, and can be used to find the measurements of a specific bearing. Series 6200 and 6300 are the most commonly used, and typically range from 10 x 30 x 9 mm (.394 x 1.181 x .354 in) to 150 x 320 x 65 mm (5.906 x 12.598 x 2.559 in). 6000 Series. 6200 Series. 6300 Series. 6700 Series.
Vibration Exciter - APS Dynamics
The ball bearing shakers are used primarily for modal test excitation or environmental test appliions in the low frequency range < 200 Hz. Although these shakers have a long stroke (158 mm) they are still portable. Thus APS ELECTRO-SEIS® shaker are ideal tools for testing of bridges, buildings or other objects outside a laboratory.
Thin section ball bearings - EZO high precision
Chrome steel is the standard material for ball bearings thanks to its high load capacity and low noise properties. Chrome steel thin section bearings, with a steel retainer and a suitable lubricant, can be used at temperatures of 120°C constant or up to 150°C intermittent. Above these temperatures, the load capacity of chrome steel is reduced

Types of Vibration and Sound in Bearings
As such vibration and sound do not degrade bearing performance, they are accepted asnormal bearing characteristics.1 Race noiseRace noise is the most basic sound in rolling bearings. It is generated in all bearings and is a smooth andcontinuous sound. At CHG we say it sounds like “sha-ahh.”The magnitude of this sound is used to assess
