Vibrating screen | SKF | SKF
The new machine is a free circular motion vibrating screen. The vibrator unit is composed of a shaft with two bearings and counterweights. This means the main radial load rotates with the shaft while the outer ring is stationary. The application drawing is shown in fig. 1.
Vibrating screens | SKF | SKF
Vibrating screen equipment in mineral processing has a tough job. The eccentric motion with high vibration coupled with heavy loads puts a strain on components, and especially bearings that are exposed to the elements and abrasive dust. It’s an environment where equipment failure is often accepted as a cost of doing business.

Bearings for vibrating machinery - evolution.skf.com
There are many examples that confirm the superiority of the SKF spherical roller bearings for vibrating applications. The operating temperature is a measure of how well a bearing performs. In vibrating screens, SKF bearings for vibrating applications run cooler than other spherical roller bearings – more than 50° F cooler.
Shaft Vibration - an overview | ScienceDirect Topics
The API-610 allowable vibrations for pumps with sleeve bearings (oil film) are based on shaft vibration measured at rated speed and capacity. The API-610 specifies the allowable unfiltered vibration shall not exceed a velocity of 0.40 ips nor exceed a displacement of 2.0 mils peak-peak including shaft runout.
