For bearings, finding parts that perfectly match your needs is crucial. However, simply looking for standard parts may not be enough.
Custom bearings can meet virtually any customer’s needs. Your application might require needle roller or ball bearings, radial or angular contact designs, plain carbon steel or stainless steel bearings with corrosion-resistant coatings, thrust or spherical bearings, tight or loose radial clearances, sealed or unsealed designs—and many more. Bearings tailored to your application’s unique requirements.
At NSAR, we combine expert modeling software, engineering technology, and extensive technical experience to design, manufacture, and assemble bearings that best suit your needs. Concurrent engineering practices enable our die-making personnel and engineers to communicate in real time, fostering collaborative process development and maximizing design efficiency.
Partnering with a manufacturing partner that provides a one-stop service from engineering design, die-making, production, and assembly means faster, more efficient operations, lower shipping costs, and stronger intellectual property protection.

Custom bearings offer you the best of both worlds: enjoy the superior performance of a custom design while ensuring the bearings are designed, manufactured, and assembled by experts. The advantages of custom bearings include lower maintenance costs, lower operating expenses, and less downtime due to bearing failures. Therefore, consider partnering with the NSAR team to develop the best solution for your application, saving you time and money.

Custom or Off-the-Shelf – How to Decide?

When choosing between custom and off-the-shelf bearings, evaluating several key factors is crucial to ensure the most suitable choice for your application.
First, consider the specific requirements of your application. Are there special operating conditions, such as high temperatures, abnormal loads, or non-standard sizes, that off-the-shelf bearings might not meet? If the answer is yes, then custom bearings may be a better choice.
Next, assess your project budget. Custom bearings typically involve higher manufacturing and design costs, so it’s essential to determine if the additional expenditure is within your financial constraints.

In addition to cost, lead time is also a factor to consider.
Custom bearings usually require longer production cycles, which can impact your overall schedule. If faster delivery is essential, then off-the-shelf bearings may be more practical.
Finally, performance trade-offs must be considered. In some cases, off-the-shelf bearings can be tailored to specific requirements through modifications such as relubrication or material coating. For example, a thin, dense chrome plating (TCD) process can improve wear resistance, reduce friction, and enhance corrosion resistance—ideal for harsh environments such as food processing or marine environments.
This approach allows for cost-effective performance improvements, bridging the gap between standard and custom solutions.
