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
