Understanding Deep Groove Ball Insulated Bearings
Deep groove ball insulated bearings are a hot-selling insulated product with a wide range of applications, such as SKF 6317M/C3VL0241, SKF 6214M/C4VL0241, FAG 6319-J20AA-C3, FAG 6220-J20AA-C3.
Definition
Deep groove ball insulated bearings are a special kind of deep groove ball bearings, which have added insulating properties on the basis of ordinary deep groove ball bearings. The added insulating material makes the bearings more suitable for environments where electrical insulation is required.
Material and Design
Deep groove ball bearings themselves are characterized by low noise, high speed and low friction. Through further improvement, insulated deep groove ball bearings have added electrical insulation function and environmental resistance to previous performance. The service life of the bearings is longer.
Applications of Deep Groove Ball Insulated Bearings
Insulated deep groove ball bearings are used in many fields, such as motor bearings, industrial pump bearings, HVAC system bearings, railroad traction motor bearings and so on.
Automotive Industry
Deep groove ball insulated bearings have a very important role in the automotive industry, such as in the use of electric cars and motorcycles. Deep groove ball bearings are mainly used in rear wheels, transmissions and other components. The insulation of the bearings ensures the smooth running of vehicles and the normal operation and precise performance of power tools.
Manufacturing Plants
Insulated deep groove ball bearings are used in manufacturing plants mainly for their unique properties and wide range of applications. A lot of equipment involves electrical systems; insulated bearings can effectively prevent the harm of galvanic corrosion caused by the passage of electric current and avoid equipment damage or safety accidents caused by electrical short circuits.
Energy Sector
Insulated deep groove ball bearings are in great demand in new energy fields, such as wind power and power plants. Generator equipment generates electromagnetic fields during operation, which can cause damage to the bearings. Insulated deep groove ball bearings not only provide the necessary mechanical support and rotational function but also protect the motor equipment from galvanic corrosion through insulating properties.
Selecting the Right Insulated Bearing
According to the different use environments and equipment requirements, choose the right insulation bearing for production efficiency and equipment safety to play a multiplier effect.
Criteria for Selection
Choosing the right insulated bearing requires consideration of two main factors: load and environment. Deep groove ball insulated bearings are subjected to pure radial force action and have the advantages of high-speed performance, low coefficient of friction and high accuracy. In harsh environments such as strong acids and alkalis and high-temperature environments, the insulated bearings used need to be treated with special materials or coatings.
Long-Term Benefits
Cost-effectiveness and service life are also factors to be considered. Insulated bearings need to be designed and have a service life that meets the needs of the application and are typically more durable than ordinary bearings. Although insulated bearings have a higher initial cost, their economy and reliability over the long term make them cost-effective.
Maintenance and Longevity
Routine Maintenance
Routine maintenance of insulated bearings contains a number of aspects:
- Keep clean: The bearing inspection needs to be done before the bearing surface, the bearing oil seal and the surrounding parts are checked to determine whether there are bad symptoms, and timely replacement is needed.
- Keep lubrication: check whether there are pollutants in the lubricant, and replace the bearing lubricant regularly.
- Please pay attention to the working environment: when checking the bearings, never expose them to contaminants or moisture in the environment.
- Sealing of bearings: Good sealing can ensure the machine operates normally, reduces noise, and prolongs the life of the parts concerned.
Common Issues
Common problems of insulated bearings mainly include galvanic corrosion and cage failure.
- Galvanic corrosion problem: Galvanic corrosion is a common problem in the maintenance of insulated bearings. Measures to prevent galvanic corrosion include the use of insulated bearings at the initial stage, and the selection of bearings with 200 μm insulating coatings (corresponding to a breakdown voltage of 3,000 VDC) can be more effective in preventing galvanic corrosion.
- Cage Failure: Cage failure is another common problem in the maintenance of insulated bearings. Measures to prevent cage failure include selecting the proper cage material and design during bearing selection, such as using brass cages to minimize the effects of vibration and shock on the cage.
Extending Life
In order to better extend the bearing life, we need to choose the right lubrication system and high-quality lubricant, follow the correct installation and maintenance requirements, choose the right type of bearing, and replace the fatigue bearings in a regular and timely manner.

Frequently Asked Questions:
What is a deep groove ball-insulated bearing?
Deep groove ball insulated bearings are special deep groove ball bearings that are electrically insulated by spraying a layer of insulating material on the surface of the inner or outer ring.
Why choose insulated bearings over others?
Insulated bearings are chosen for their unique insulating properties. In the modern industrial field, machinery and equipment will face corrosion damage from electric currents, compared with ordinary bearings, and insulated bearings can better protect the bearings and equipment’s safety.
How do insulated bearings enhance electric motor performance?
Insulated bearings achieve good insulating properties and avoid the galvanic corrosion effect of induced currents on the bearings by means of high-quality laminates sprayed on the outer surface. Good insulation protects the safety of motor use and improves the overall performance and service life of the motor.
Can insulated bearings help in reducing maintenance costs?
Insulated bearings can help reduce maintenance costs. Because the insulation of bearings can well avoid galvanic damage and reduce the damage rate of machines and bearings, it reduces the number of repairs and expenses.
Are there different types of insulated bearings?
Yes, insulated bearings come in different types. Insulated bearings include, but are not limited to, deep groove ball insulated bearings, cylindrical roller insulated bearings, hybrid ceramic bearings, and more.
