Silicon Nitride Ball/High Precision Ball/G3/G5/G10/INNOVACERA

Product Overview:

Silicon Nitride, Si3 N4, ceramic has become the standard ceramic ball material for hybrid Ball Bearings.
This material is very hard, over 2000 Knoop, and very wear resistant.
The weight of silicon nitride balls in only 40% of steel at 3.2 grams per CM3.
This material is hot isostatic pressed from 1 to 3 micro powder.
This material has excellent facture toughness even at elevated temperature.
We will custom manufacture silicon nitride balls in any diameter.
We maintain complete facilities to modify silicon nitride ceramic balls with flats, holes or other details.

Features:

• Density 3.25 g/cm3 (59% lower than steel)
• Excellent wearability
• Max working temperature up to +800°C
• Low coefficient of thermal expansion
• Very high hardness Hv 1400
• Nonmagnetic
• Electrical isolating
• Self-lubricating
• Excellenct corrosion resistance
• Applicable for high speed bearings

Application:

• High end bearings
• Ball screws
• Valves
• Aero space bearings
• Windmill bearings
• Used where high wear, corrosion resistant, high temp and no lubrication needed

Innovacera develops and manufactures products made of technical ceramics for customer-specific applications.
Starting with problem analysis and generation of ideas, Innovacera carries out projects in which cost-efficiency is of paramount importance. Innovacera produces prototypes, small and larger series of custom made products in-house.
