How to Prevent Spindle Bearing Failure

Sep 02, 2019· Bearing Storage. Unused spindles should be kept clean and be rotated periodically to prevent bearings from resting in the same position. When spindles are left to sit for long periods of time the consistent pressure on portions of the bearings can cause flat spots to form. Misshapen bearings are a common cause of spindle failure.

An Overview of Bearing Vibration Analysis

result bearing manufacturers have developed vibration tests as an effective method for measuring quality. A common approach is to mount the bearing on a quiet running spindle and measure the radial velocity at a point on the bearing’s outer ring in three frequency bands, 50-300, 300-1800 and 1800-10000Hz. The bearing must meet RMS velocity
