Precautions for Using Motor Bearings

Motor bearings are precision parts, and their use must be carried out with care. No matter how high performance bearings are used, if they are not used properly, the expected high performance will not be achieved. As a motor bearings supplier, I’d like to share with you about the precautions when using the motor bearings.

Motor Bearing

Precautions on the Use of Motor Bearings

(1) Keep the bearing and its surrounding environment clean

Even if the tiny dust invisible to the naked eye enters the bearing, it will increase the wear, vibration and noise of the bearing. Bearings and their surrounding accessories should be kept clean, especially dust and dirt, and tools and working environment must also be kept clean.

(2) Installation should be done carefully

No strong stamping, no direct hammering of the bearing, no pressure transfer through the rolling body is allowed.

(3) Use suitable and accurate installation tools

Try to use special tools, strongly avoid the use of cloth and short fiber and so on.

(4) Prevent the bearing from rusting

When picking up the bearings directly by hand, wash away the sweat on your hands sufficiently and apply high quality mineral oil before operation, especially in the rainy season and summer to prevent rust. However, under certain special operating conditions, bearings can obtain a longer life than traditionally calculated, especially under light loads. These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricant film and the possible surface damage caused by contaminants is limited. In fact, under ideal conditions, so-called permanent bearing life is possible.

Common Problems and Countermeasures in the Use of Motor Bearings

Problem: Strong Metallic Sound

Causes and countermeasures:

1. Abnormal load: To choose the appropriate assembly clearance and preload.

2. Poor assembly: To improve the machining accuracy of the shaft, improve the installation method.

3. Insufficient lubricant: To supply or use suitable lubricant

Problem: Rule Sound

Cause and Countermeasures.

1. Foreign objects cause trench rust, indentation, scarring: Clean the relevant parts and use clean grease.

2. Groove flaking: This is due to fatigue wear, please replace the bearing

Problem: Irregular Sound

Causes and Countermeasures.

1.  Foreign body invasion: To clean the relevant parts and use clean grease.

2. Clearance is too large: Pay attention to the fit and choose the appropriate clearance.

Steel ball injury: this is because the steel ball fatigue spalling or foreign body jamming, you can replace the bearing.

Problem: Abnormal Temperature Rise

Causes and Countermeasures.

1. Too much lubricant: To reduce lubricant.

2. Insufficient lubricant, or unsuitable: To increase lubricant or choose suitable lubricant

Problem: Large Vibration of Shaft Rotation

Causes and Countermeasures:

1. Bad assembly: To improve the machining accuracy of the shaft and improve the installation method.

2. Foreign material intrusion: Clean the relevant parts and use clean grease.
