Custom Electrical Insulating Bearings for Ultimate Equipment Protection
TFL can customize insulated bearing solutions to meet your unique needs, preventing electro-corrosion, eliminating shaft current, and extending the lifespan of your equipment.
What are custom insulating bearings?
When standard, off-the-shelf bearings cannot meet your unique equipment design or demanding operational needs, a custom-engineered bearing is the solution.
It is designed and manufactured through a dedicated process to fit your exact specifications, including non-standard dimensions, special materials, or unique performance features.
Our Customization Options
Leveraging nearly two decades of dedicated expertise, TFL stands as a leading manufacturer of electrical insulating bearings in China. Our extensive experience and robust technical capabilities enable us to address the unique challenges of diverse operating environments.
We engineer and produce custom insulated bearings tailored to your specific needs, from high-voltage motors to precision equipment. Our commitment to advanced R&D and rigorous quality control ensures that every custom bearing we deliver exceeds industry standards in both performance and reliability.
We specialize in high-performance coated insulating bearings. Instead of a one-size-fits-all approach, we tailor the coating solution to your specific operating conditions, including voltage levels, temperature, and humidity.
Our capabilities feature a range of proven coating options, highlighted by our proprietary, patented insulation coating. This advanced formula is rigorously tested to provide superior dielectric strength, with a breakdown voltage protection of up to 3000V DC, offering unparalleled security for your critical assets.
Our custom manufacturing capabilities cover a wide array of the most common bearing types to ensure seamless integration into your machinery. We regularly provide custom insulated versions of:
Deep Groove Ball Bearings
Cylindrical Roller Bearings
Tapered Roller Bearings
Spherical Roller Bearings
If your application requires a different bearing type, please contact our engineering team. We are ready to explore a solution for you.
Break free from standard catalog constraints. We specialize in manufacturing non-standard dimension insulating bearings to fit your unique design specifications perfectly. Whether you require custom inner diameters, outer diameters, or widths, we can produce them with precision to meet your exact spatial requirements across all industries.
A bearing's performance goes beyond its dimensions and insulation. We offer in-depth customization of the bearing's internal structure to optimize it for your specific requirements of speed, load, temperature, and vibration.
Cages: We can design and implement various cage materials and designs. This includes high-speed polyamide cages for enhanced rotational performance or robust machined brass cages for heavy-load and high-temperature applications, ensuring operational stability under stress.
Seals & Shields: To protect against contaminants and retain lubrication, we can customize the sealing solution. Choose from non-contact shields (ZZ) for low friction or contact seals (e.g., 2RS) for superior protection in dusty, moist, or harsh environments.
Our customization potential extends across every aspect of the bearing's design to provide you with a true one-stop solution. You can work with our engineers to specify these and many other features:
Custom Precision Ratings (e.g., P5, P4)
Custom Clearance (e.g., C3, C4, CN)
Custom Lubrication (High-temp grease, specific oil, etc.)
Custom Bearing Steel Material
Custom Heat Treatment

General FAQ
How do I start the customization process for an electrical insulating bearing?
- Provide us with your technical requirements via our inquiry form or email. This should include the bearing model/dimensions, required breakdown voltage, operating conditions (like RPM, temperature), and any technical drawings.
- Our engineering team will evaluate your needs and propose a professional technical solution and a formal quotation.
- Once confirmed, we will proceed with production and ensure on-time delivery.
What is the typical lead time for a custom insulated bearing order?
The lead time for custom bearings depends on design complexity, material availability, and order quantity. A straightforward customization might take a few weeks, while a completely new and complex design may require a longer period. After your technical solution is confirmed, our sales team will provide you with an accurate and reliable delivery schedule.
How do you guarantee the insulation performance and quality of your custom insulated bearings?
We conduct high-voltage insulation performance tests on the products to ensure that their breakdown voltage values meet or exceed your specification requirements.
In addition, we also perform dimensional accuracy checks, material analysis, and appearance inspections to ensure that the products you receive are superior to industry standards in all aspects.
