Full Ceramic Bearings 6000 6002 6003

When regular steel bearings keep failing-whether from rust, moisture, or electrical damage-a lot of equipment makers switch to full ceramic bearings.

 

The 6000 series is one of the most popular deep groove ball bearing families out there. Among them, the 6000, 6002, and 6003 show up all the time in pumps, motors, lab gear, food machinery, and automation systems.

 

We offer these bearings in both Silicon Nitride (Si₃N₄) and Zirconia (ZrO₂). For tougher operating conditions, we also supply them with ceramic balls and PEEK cages.

 

 

Bearing Model	Bore (d)	Outer Diameter (D)	Width (B)
6000	10 mm	26 mm	8 mm
6002	15 mm	32 mm	9 mm
6003	17 mm	35 mm	10 mm

 

 

Model	Typical Use	Relative Load Capacity
6000	Small motors, instruments, compact equipment	Light
6002	Pumps, automation equipment, gearboxes	Medium
6003	Industrial motors, conveyors, machinery	Higher

 

 

Silicon Nitride (Si₃N₄)

 

People tend to pick silicon nitride when speed and light weight matter most.

Common uses:

Electric motors

Semiconductor equipment

High-speed machinery

Precision automation systems

 

Zirconia (ZrO₂)

 

Zirconia gets chosen a lot for wet or chemically harsh environments.

Common uses:

Chemical pumps

Food processing equipment

Marine systems

Laboratory instruments

Most customers aren't looking for ceramic bearings just because they sound cool.

Usually, there's a real problem they need to solve.

Some need a bearing that simply won't rust.

Some need electrical insulation.

Others are tired of swapping out bearings every few months in washdown or chemical environments.

Compared to steel, full ceramic bearings last a lot longer in demanding applications.

Are 6000, 6002 and 6003 bearings interchangeable?

No. Each one has different dimensions. You need to match the bearing to your shaft size and housing.

 

Which model is used most often?

It's our most frequently requested size because it fits so many industrial applications.

 

Can these bearings run in water?

Yes. That's one of the main reasons people buy them-steel bearings would rust out, but ceramic handles wet environments just fine.

 

Do ceramic bearings need grease?

Sometimes yes, sometimes no. Depends on your speed, load, and operating conditions.

 

Which material should I pick?

Silicon nitride for higher speeds. Zirconia for chemical resistance and wet environments.

 

Can you do OEM packaging?

Yes. Custom labels, packaging, and private branding are all available for OEM customers.
