Ceramic Bearing & Ceramic Balls

Product Details:

ZrO2 Angular contact ball ceramic bearings Angular contact ball bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them. As matched pairs of bearings, preload for them is more convenient

An Efficient, Longer-Lasting & Virtually Contamination-Free Solution for Ceramic Grinding & Milling

Zirconia (YSZ) grinding media is the most durable and efficient media for ball milling and attrition milling of ceramic materials. Zirconia grinding media provides a virtually contamination-free ball milling solution for a variety of industries.

15mm,20mm,25mm,30mm.

CYLINDRICAL ZIRCONIA (YSZ) GRINDING MEDIA
5mm,7.5mm,10mm,12mm,15mm,20mm

Advantages of Zirconia Grinding Media

· Ultra low wear loss as a result of the transformation-toughening mechanism unique to the yttria stabilized zirconia (YSZ) material system.

· Higher grinding efficiency and reduced grinding time due to zirconia’s higher density (compared with alumina and glass).

· Most durable grinding material, reducing operational cost in the long run. Wear rate substantially lower than Al₂O₃, CeO₂-ZrO₂, and MgO-ZrO₂ grinding media.

· Suitable for high velocity operations and wet grinding operations.

Applications of Zirconia Grinding Media

· Iron- and chrome-based magnetic materials (for audio/video recording tapes) and other magnetic materials.

· Electronic-grade ceramics (ferroelectric, piezoelectric, dielectric, capacitors, sensors, etc.), advanced structural ceramics, and other ceramic ingredients.

· Nanostructured and superfine powders.

· Toner materials for photocopiers and laser printers.

· Inks, dyes, paint, and other pigments.

· Pharmaceutical, food, chemical, and textile applications.

· Lab milling operations demanding minimized contamination from milling media.

Criteria in Selecting Size of Zirconia Grinding Media

· Larger-sized media are more efficient in breaking up large particles.

· Smaller media are more efficient in milling smaller particles because of higher effective contact area.

· Larger media sizes are favored in many conventional ball mills. Smaller sizes are more appropriate for attritors. For example, 5mm media are used in many attrition mill applications, whereas 10-15 mm may be a good start for a lab ball mill. For small-media mills, media sizes are typically smaller than 2 mm.

· Another important criterion in selecting media size is the gap size between stirring arms and mill walls. Media size should be significantly smaller than the gap size to prevent jamming.

Product Details:

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C. The high thermal conductivity coupled with low thermal expansion and high strength give this material exceptional thermal shock resistant qualities. Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600°C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces. The electrical conduction of the material has lead to its use in resistance heating elements for electric furnaces, and as a key component in thermistors (temperature variable resistors) and in varistors (voltage variable resistors).

Product Details:

Si3N4 Full ceramic bearing of full complement balls has an add-ball gap on its side. Because using no retainer design, the bearing is able to install more ceramic balls than the standard construction, so the heavier load ability increased more. In addition, to avoid the limited of the retainer’s material, this bearing is same as the full ceramic bearing of ceramic cage has corrosion resistance and high temperature application. This series of bearing is not for high –speed choice, it should be to install on the unforced side.

Ceramic ball have the following performance as low density, high strength, low friction, wear resistance, self-lubrication and higher rigidity, it’s the best choice for rollers of the hybrid construction ceramic which are used in high-speed, high-precision and long life applications.

Product Details:

Silicon Nitride (Si3N4) Ceramic Balls are formed from a new material suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Silicon Nitride is non-porous, non-magnetic, non corrosive, lighter than steel and, in ball form, is harder than steel. Because ceramic balls are non-porous they are virtually frictionless and are capable of spinning faster than steel balls.
