Prevent Electrical Damage, Extend the Service Life of Bearings

When deep groove ball bearings with electrical insulation operate in an environment with current, an annoying problem is inevitable-electrical damage. Electrical corrosion is usually manifested as ripple damage or small pits. This seemingly insignificant damage is often the culprit behind bearing vibration, noise, and even failure.

To avoid this hidden danger, it is very necessary to replace deep groove ball bearings with electrical insulation coatings. This can block destructive currents from the root, extend the service life of the bearings, and provide solid and reliable protection for your bearings.

Inheriting All the Advantages of Deep Groove Ball Bearings

Electrically insulated deep groove ball bearings are essentially a special type of deep groove ball bearing. Their structure is exactly the same as that of standard deep groove ball bearings, except that the rings have a precise insulating coating, thereby adding the property of electrical insulation to the deep groove ball bearings.

Deep groove ball bearings, as one of the most widely used bearing types, have a simple structure, are high-speed and durable, and can withstand both radial and axial loads, making them suitable for most complex working conditions. Therefore, electrically insulated deep groove ball bearings, which combine the advantages of deep groove ball bearings and electrical insulation, have become the first choice in various industries.

FREQUENTLY ASKED QUESTIONS

How can I determine if I need to replace with an electrically insulated deep groove ball bearing?

A comprehensive judgment can be made based on your bearing working environment and bearing condition:

Analyze the working environment: If your equipment uses a variable frequency drive (VFD), especially for large power motor equipment, it is very necessary to replace the electrically insulated bearing to reduce the downtime caused by bearing problems.
Observe the bearing condition: If the bearing shows vibration and noise, temperature rise, and deterioration of the lubricant, it may be an abnormality caused by electrical corrosion.
Check the bearing damage: If the bearing fails prematurely or has small pits on the surface or the raceway discoloration, it is very necessary to replace the electrically insulated deep groove ball bearing at this time.

Although the price of the electrically insulated deep groove ball bearing may be higher than that of the standard deep groove ball bearing of the same model, it can significantly increase the service life of the bearing and the stability of the equipment. As a preventive investment, it is very necessary.

If you are worried about the cost, you can consider TFL bearings: Our self-produced electrically insulated deep groove ball bearings have the quality to replace mainstream brands, but the price is more reasonable. Contact us at any time to get the latest quotation.

Will replacing the electrically insulated deep groove ball bearing affect the bearing's load and speed and other attributes?

Whether the load and speed of the bearing and other attributes are affected depends on the type of electrically insulated deep groove ball bearing you choose:

Insulated coating deep groove ball bearing: This type of bearing has the same dynamic and static load capacity, speed, and bearing size as the standard bearing of the same model. It can be directly replaced on a 1:1 basis and is the most cost-effective and efficient electrical insulation solution.
Hybrid ceramic deep groove ball bearing: Compared with the standard bearing of the same model, this type of bearing has a significantly increased speed capacity due to the hybrid ceramic rolling elements, but the dynamic load is slightly lower than that of the all-steel bearing of the same model. Before replacement, you may need to reconsider the load and speed requirements.

If you are still confused about replacing the bearing, please feel free to contact us at any time! Just tell us your needs, and we will provide you with professional selection advice and purchase solutions.

Are roller bearings more expensive than ball bearings?

Under normal installation conditions, the coating of high-quality deep groove ball bearings with electrical insulation generally does not wear or fall off. However, the following extreme situations should be noted:

Severe mechanical shock and improper installation
Improper clearance fit of the bearing housing or poor machining accuracy, causing significant squeezing force and damaging the coating
Extreme vibration or huge impact loads
Exposure to highly corrosive chemical environments

Apart from the above extreme conditions, the bearing manufacturer's coating technology, quality control, and process stability also greatly affect the quality of the coating. It is recommended to choose reliable bearing brands such as SKF, FAG, NSK, and TFL to ensure the service life of the coating.
