Bearings for Electric Drives

High-Speed Electric Drives Require High-Speed Angular Contact Bearings

When it comes to electric drives, there are many components to consider when trying to optimize your design. While most of the limelight tends to shine on the stator, rotor and the cooling system, the unsung hero of electric drives truly is the bearings. They show up every day and bear the loads demanded of them and never ask for any recognition. But it’s this humbleness of bearings that presents opportunity.

Many Engineers take bearings for granted and overlook the nuances that make each bearing unique. These are not commodified components. Each bearing has a story to tell. Those who take the time to understand what makes their electric drive go around are the ones who will find the diamond in the rough that makes their electric drive stand above the competition.

Combine that with a bearing supplier that offers the white glove service to ensure you find that diamond in the rough of a bearing, and then your electric drive truly will be unstoppable.

High-Speed Electric Drives - Efficient, Compact, Integrative

Electric Drive Motors

For industrial high-speed electric drives, sustained force & part life are critical requirements for long-lasting, high-performing systems.

That’s where GMN angular contact bearings AND our top-quality engineering expertise can help. At GMN Bearing USA, we deliver a one-two punch of top-quality, German-made Angular Contact Bearings AND practical Engineering know-how to help you gain efficiencies and increase productivity.

But First, Why Angular Contact Bearings?

Angular contact bearings can play an essential role in an efficient electric drive.  Learn more about the markets & applications we serve

One advantage that angular contact bearings offer is that they are optimized to run at high speeds for long durations of time. This can be leveraged to improve overall performance and robustness of your electric drive. Higher rotational speeds permit more power delivery resulting in faster operation execution, while angular contact bearings still maintain smoothness of operation for a job well done. This is accomplished through increased precision of the bearing raceways, resulting in less dimensional variation, as well as preloading, which optimizes the ball action for increased efficiency.

4 Things to Consider When Maximizing Angular Contact Bearings for Electric Drives

1.) Selecting the right cage for your application is a lot like choosing the right shoes to wear. If your application requires separating and positioning the balls with a low friction coefficient at temperatures up to 120° C, then our standard TA Phenolic cage is for you. For applications that are a bit more demanding and require longer service life through lower friction and constant grease lubrication due to the formation of grease reservoirs in provided cage pockets at temperatures up to 250° C, then upgrading to our TXM PEEK cage is the way to go.

2.) One thing that makes angular contact bearings unique is that they have a contact angle that is selected based upon the loading split between the axial and radial directions. For most electric drive applications, a 15° contact angle will be optimal as most of the loading will be transmitted radially. In some cases, a 25° contact angle will be optimal as more loading will need to be transmitted axially. If our KH bearings are selected, then they will come with a 17° contact angle for slightly improved loading in the axial direction compared to our standard 15° contact angle.

3.) Our standard ball material is bearing steel, which offers the strength and durability to achieve the speed and load ratings that customers have come to expect from GMN, while not breaking the bank. However, if your application demands higher speeds, longer service life and greater rigidity, then our ceramic ball bearings will be up to the task.

4.) There are a few preload options that can be considered depending on the design constraints of your electric drive. A light preload will offer the longest bearing life and greatest load capacity but comes at the cost of reduced rigidity. A heavy preload will offer the greatest rigidity but will come at the cost of reduced bearing life and load capacity. A medium preload offers a good compromise between bearing life, load capacity and rigidity.

If you're unsure where to start with choosing an optimal angular contact bearing for your electric drive application, contact our engineers for assistance.

GMN Angular Contact Bearings for High-Speed Electric Drives Drive Stronger & Last Longer

Electric Drive Motor

Did you know that the #1 most overlooked component of electric drives is the bearings? While the motor gets all the credit, it’s the bearings that hold everything together to ensure things run smoothly. The faster the speed of the electric drive, the harder the bearings must work to support the motor, but the work truly begins in the bearing selection process.

While concluding that angular contact bearings are ideal for your electric drive is a great first step, the next step is selecting a bearing brand that you can trust. There are many different companies that can supply you with angular contact bearings for your electric drive, but there is only one bearing manufacturer that brings the expertise of supplying high quality precision bearings, as well as high speed electric motors, all under one roof; GMN Bearing USA.

The GMN Difference

Around here, we like to say that “good enough” just doesn’t cut it. That’s why when it comes to our precision parts, there is no competition. Here are just a few reasons why:


Tolerancing is critical and that’s why all GMN P4+ bearings are marked with the exact value of the ID, OD & W. They are also laser etched on the inner ring indicating the high point. This allows for even spacing to help with the balance of the bearing set.

P2 Runouts

All GMN P4+ are manufactured with P2 runouts, translating to better bearing performance & longer life.

Universal Matching

GMN tolerances are so tight, our angular contact bearings can achieve the same benefits of using matched sets from other brands. We can easily cross from various brands like SKF, NSK, Barden, NTN, Timken & more.

No Grease Fees

In our clean & controlled environment, we ensure your bearings have the precise amount of lubrication, for no extra charge. This service is part of our partnership with you.
