When replacing a bearing of vibration motor, we recommend to replace both bearings of a motor, even if only one bearing should be defective. A defective bearing will also always cause damage to the other bearing. The second bearing will fail after a short time.
The bearing housings must also be replaced every 2nd time that the bearings are replaced.
