Full ceramic Self Aligning Ball Bearing

For many harsh working scenarios, ordinary steel bearings just can't hold up over time.

A lot of our customers come to us with the same problem: their steel bearings break down prematurely after long-term contact with chemicals, moisture or electric current. If this sounds familiar to you, full ceramic self-aligning ball bearings will be a much more reliable pick.

Unlike regular steel bearings, this model features both rings and balls made of ceramic. It's completely rust-proof and non-conductive. Plus, the self-aligning structure works perfectly even when the shaft and housing aren't fully aligned with each other.

For devices operating in tough conditions, switching to this bearing means fewer part replacements and less unexpected downtime.

We offer multiple precision grades to match different usage scenarios, from general industrial use to high-precision mechanical equipment. The wide temperature tolerance also allows the bearing to adapt to extremely cold or high-temperature working environments steadily.

Chemical processing equipment is one of the most common use cases.

Steel bearings tend to corrode rapidly when exposed to corrosive liquids and fumes, while ceramic versions stay intact and free from rust in such environments.

They are also widely used in semiconductor production equipment. Thanks to the non-conductive property of ceramic, these bearings can effectively prevent electrical damage to the whole system.

Food processing machinery is another ideal match. The equipment needs frequent water cleaning, and standard steel bearings are easy to wear out here. Ceramic bearings, however, boast a far longer service life.

Besides the above, we also provide these bearings for lab devices, marine equipment and special-purpose pumps.

We mainly offer two ceramic materials: silicon nitride and zirconia, and you can choose according to your actual needs.

Silicon nitride is lighter in weight, so it's the go-to option for equipment running at high speeds.

Zirconia is relatively heavier, yet it delivers outstanding anti-corrosion performance, which makes it perfect for scenarios where corrosion resistance is the top priority.

If you're not sure which material fits your working conditions, feel free to tell us your requirements and we'll give you professional suggestions.

Will ceramic bearings get rusty?

Absolutely not. Unlike steel, ceramic materials do not oxidize or rust, even when exposed to moisture and corrosive substances for a long time.

Can these bearings run without lubricant?

Dry running is achievable in some light-load and low-speed applications. For high-speed or heavy-load use, proper lubrication is still suggested to extend service life. The specific usage plan depends on your actual working speed and load.

Are ceramic bearings magnetic?

No, our full ceramic bearings are completely non-magnetic and will not be affected by external magnetic fields.

Can I get bearings in non-standard sizes?

Yes. We accept non-standard size customization and can develop exclusive products based on your unique equipment requirements for OEM projects.

Which material is better, silicon nitride or zirconia?

There is no absolute better option. Silicon nitride suits high-speed operation, while zirconia excels in anti-corrosion scenarios. The final choice should be decided by your on-site working conditions.

We keep a complete range of standard sizes in stock for fast delivery. Meanwhile, we fully support customized production to meet personalized project requirements.

Our factory can manufacture bearings strictly according to your technical drawings or physical samples. We can customize dimensions, precision levels, surface markings and packaging solutions as you request, catering to OEM and special project demands.

To work out an accurate quotation and recommend the most suitable bearing solution for you, we usually need to collect a few key information first:

Exact bearing dimensions

Actual working temperature range

Normal operating speed

Working load parameters

Annual purchase quantity

Providing these details will help us optimize the product configuration and ensure the bearings perform well in your equipment.
