CeramicSpeed Silicon Nitride Balls | Bearings

In addition to their use in bearings, these unique balls are also used in high pressure valves in common rail pumps, in diesel motors and other valve types.

We always have 150 different ball sizes in stock, ranging from 2.5 mm to 50 mm. Our prices are competitive, and we have a short lead time. 

CeramicSpeed in our bearings: CeramicSpeed balls are used in our bearings; however they are also used in valves, where the ceramic balls have a series of properties which are valuable in demanding environments.

Advantages:

• Reduced wear on the valve seat
• Tighter fit – remains tight at a higher pressure
• Doesn’t rust
• 63% stiffer – reduced warp
• 58% lighter
• Consistent high quality
• Not brittle – can resist blows and shocks. See this test
• Extremely hard, smooth and round
• Guaranteed against stray currents
• Reduced wear, and doesn’t crack from contact with metal

Applications:

• Ball valves
• Insulating against electric currents / heat
• Polishing
• High pressure valves
• Hydraulics
