Materials

We make bearings in a wide variety of materials, and can help you select the best ones for your requirements.

High-performance options include:

Nickel-Based Superalloys

Example Grades: Inconel® 625, 718 X-750; Hastelloy® C-276

High strength, good hardness, superior creep, and fatigue resistance. 718 isn’t as hard as hardened steels (it tops out at ~45 HRC compared to the ~60 HRC of tool steels), but the ability to retain its properties close to melting temperature makes it the choice for high-temperature applications.

Cobalt-Based Superalloys

Example Grades: Stellite® 6, Haynes® 188, Ultimet®

Cobalt-chromium superalloys are unmatched wear and abrasion resistance, and are corrosion and high-temperature resistant.

Multi-Alloys

Example Grades: Inconel® 718, Stellite® 20

Functionally-graded and multi-alloy bearings provide targeted performance—such as enhanced wear or corrosion resistance—where needed most.

Tool Steels

Example Grades: H11, H13, M2, M50, T1, D2

Tool steels, like hot work chromium H series and the high-speed steel M series, are high-hardness, high-strength steels that retain their properties at high temperatures, and even have some corrosion resistance.

Other Alloys

Tungsten carbide: Hardness of ceramic but weldability of a superalloy. For extreme conditions.

Titanium, Invar, etc: Most rolling element bearings require a high-hardness alloy to function properly, but there are some applications where softer components may be acceptable to achieve other goals.

Looking for something else?

Working with wire feedstock means our material options are pretty extensive. We can also produce multi-alloy components, which are ideal for bearings that might need targeted enhancements due to application conditions.

Production Process

Hybrid Manufacturing with Wire-Laser Metal Deposition (w-LMD)

Hybrid manufacturing is an advanced manufacturing method that combines additive and subtractive within the same system. At Hybrid CNC Parts, we use Haas CNCs with integrated w-LMD Meltio engines. It’s a fast and efficient method for producing precision components.

w-LMD is a direct energy deposition (DED) process that uses lasers to melt metal wire feedstock as it’s being deposited, building up components layer by layer. By using wire feedstock, your material choice options are abundant.

USE CASE

Needle Roller Bearings for Nuclear Systems

These custom engineered and produced bearings are designed for modern nuclear reactor refueling mechanisms, where temperatures can reach 1,000°F. Requirements included the need for bearings of high strength, high hardness, and corrosion resistance.

Project Notes:

Nickel alloy 718, AWS 5.21 ERCoCr-A (cobalt-based alloy), and H11 were selected for their heat- and corrosion-resistance properties.
Witness coupons made and tested with every build for process control and material property validation.
In situ fully-hardened state of H11 achieved without post-processing—reducing lead times, production costs, and increasing performance.

Benefits of Custom-Made Bearings

Meet exact requirements

Your requirements are unique and all the off-the-shelf bearings are not quite right. Maybe close, but it would mean adjusting the project to make them work. Custom bearings can be made to suit your exact requirements, no matter how niche. Not sure where to start? We can help. Contact us to get started.

Overcome spatial limitations

In some applications that can be little choice for shaft and housing dimensions, like in spacecraft where there isn’t much room to spread out, or geothermal wells where every inch of the drilled borehole is important. Being able to design bearings around other mechanical requirements is a critical consideration.

Supply chain reliability

While some bearings are limited in their production depending on the availability of raw materials, all of our bearings are produced using readily available metal wire feedstock, equating to more reliable lead times.

Improved efficiency

Faster production cycles using hybrid manufacturing due to rapid prototyping, quick design iteration, and lack of extensive tool changes. It also produces less material waste compared to subtractive-only methods.
