Design & Engineering

We are constantly evolving and improving ourselves as a quality bearing manufacturer. Our company utilizes a variety of development tools including Romax bearing modeling and analysis in order to design new applications. Other tools include internally developed programs and Autodesk Inventor for bearing assembly design. Our experts will analyze your current bearing and give knowledgeable recommendations to improve life or reduce your overall cost. We can also take your precise design inputs and recommend a bearing based on our vast years of experience. You don’t need to worry about having to pick a bearing out of a catalog. Our team will design a bearing to fit your exact application.

WIre used for Bearings

Heat Treating

Universal Bearings operates various heat-treat machines in-house. We proudly maintain the highest level of quality. The bulk of our products are “neutral hardened” in our heat treating process, but we can also provide induction hardening, carbonitriding, ferritic nitro-carburizing and nitriding processes. In any case, if special requirements are needed for surface treatment, we have reliable secondary sources for those special surface treatment pursuant to customer’s requirements. We work with trusted and knowledgeable industry partners to ensure all of our clients’ requirements are met. Find out more about our heat treatment options to see what these processes have to offer your bearings.

Heat Treating

Testing & Quality Control

As an industry leader, we have various testing machines to perform the level of durability for each bearing product. This will include but is not limited to: back-to-back test stand machines; planetary application testing machines; thrust bearing testing machines; radial bearing testing machines; and flexible radial or thrust load machines. These state-of-the-art machines allow us to do design validation tests on new applications as well as current production bearings. We also have an in-house metallurgical lab to validate both in-house and outside sources. Our quality standards provide our customers with peace of mind. We diligently maintain our IATF 16949, ISO 14001, and ISO 9001 certifications and are certified to General Motors Built in Quality Supply requirements.
