What are Custom Bearings?

Custom bearings are bearings that are specifically designed to meet the requirements that most standard bearings simply can’t fulfill. Unlike typical bearings, our custom options are specifically tailored for your needs through a comprehensive customization process. Our goal is always to provide you with a product that performs well, lasts long, and meets your exact specifications.

Generally, customization involves a highly detailed bearing design process, where we determine the size, materials, precision, and lubrication needed for your application.

LILY Bearing’s Custom Design Capabilities

At LILY Bearing, we have more than two decades of experience and extensive design capabilities that help us cater to diverse application needs.

Custom Precision

An improperly sized bearing can cause project delays, damage, and a lot of headaches. As such, applications that demand exact tolerances and smoother operation require precision. Even the slightest deviation can have a massive effect on performance and costs. That’s why our services are trusted by clients in the medical, aerospace, and transportation industries.

Custom Lubrication

Proper lubrication is crucial for many applications where reduced friction and increased longevity are needed. Depending on your needs (i.e., temperature, speeds, climate, etc.), we may also recommend additional methods of lubrication. Not only does this ensure your bearings operate efficiently, but it also helps to maintain their performance for years to come. We also handle custom bearing designs that require specialized greases, coatings, and other specific lubrication needs.

Types of Custom Bearings

With our level of experience and expertise, LILY Bearing is able to provide various types of custom bearings to meet your specific configuration needs:

● Ball Bearings
Excellent for radial and axial loads.
● Roller Bearings
Better for heavy-duty applications.
● Slewing Ring Bearings
Often used in large machinery and robotics.
● Turntable Bearings
Mainly for rotational applications.
● Thin Bearings
For compact spaces that require absolute precision.
● Miniature Bearings with Flanges
Perfect for high-precision, small-scale applications.
● Thrust Bearings
Ideal for handling axial loads in high-pressure applications.

Advantages of Custom Bearings

Opting for custom bearings offers several benefits:

Performance Optimization

Because custom bearings are designed to meet such exact requirements, they lead to improved efficiency, smoother operation, and the ability to handle unique operational conditions.


The custom bearings we design are built to last. Tailoring the materials and design to your application increases durability and reduces the frequency of replacements. That means it’s more cost effective and efficient for you.


A precise design ensures that each bearing meets the exact specifications of your application. This translates to consistent performance, minimizing the risk of unexpected failures and enhancing the overall dependability of your equipment.

High-Load Capacity

Custom bearings are engineered to support specific load requirements, whether they involve radial, axial, or combined loads. This capability ensures optimal performance even under heavy-duty conditions, providing the necessary support for demanding applications.

Corrosion Resistance

Custom bearings can be manufactured using materials like stainless steel and ceramics, which offer superior resistance to corrosion. This feature is particularly important in environments exposed to moisture, chemicals, or extreme temperatures, extending the lifespan of the bearings and maintaining their performance.

Custom Material

We offer a variety of materials to meet your needs. Those materials include, but are not limited to:

● 52100 Steel
Best known for its hardness and resistance to wear.
● Polyurethane
Due to its elasticity, this is most recommended for roller bearings and similar applications.
● 440C, 304, 316L Stainless Steel
Affordable and excellent for corrosion resistance.
● Cronidur 30
A high-performance steel that’s great for extreme conditions.
● Ceramics
This includes materials like Aluminum Oxide (Al2O3), Silicon Nitride (Si3N4), Silicon Carbide (SiC), and Zirconia (ZrO2) — all of which provide high temperature and wear resistance for demanding applications.

Custom Size

We design and manufacture bearings in a wide range of sizes which can accommodate all types of applications. From consumer goods to aerospace components to high-precision bearings for machinery, we've got you covered.
