Do you know the types of wicked ceramic bearing?

self-lubricating characteristics of ceramic materials, in the ultra-high vacuum environment, it can overcome the problem that ordinary bearings cannot achieve lubrication. Note: For the above five categories of bearings, the same set of bearings can be applied to high temperature, high speed, acid and alkali, magnetic field, non-insulation, but due to different material properties (please refer to the rare earth ceramic material performance table), when customers choose products, According to your application, choose the most suitable wicked ceramic bearing.

Material classification of wicked ceramic bearing

Zirconia

Full zirconia wicked ceramic bearing has the characteristics of anti-magnetic and electrical insulation, abrasion and corrosion resistance, oil-free self-lubrication, high temperature and cold resistance, and can be used in extremely harsh environments and special conditions. Ferrules and rolling elements are made of zirconia (ZrO2) ceramics. The holder uses polytetrafluoroethylene (PTFE) as a standard configuration. Generally, glass fiber reinforced nylon 66 (RPA66-25) and special engineering plastics (PEEK, PI), stainless steel (AISISUS316), brass (Cu), etc.

Silicon nitride

Full silicon nitride wicked ceramic bearing ferrules and rolling elements are made of silicon nitride (Si3N4) ceramic materials. Generally, RPA66-25, PEEK, PI, and phenolic laminated bakelite pipes can also be used. Compared with ZrO2 materials, full wicked ceramic bearing made of SiN4 are suitable for higher speed and load capacity, as well as higher ambient temperature. At the same time, we can provide precision wicked ceramic bearings for high-speed, high-precision and high-rigidity spindles, with the highest manufacturing accuracy of P4 to UP.

Full ball bearing

The full-ball full-wicked ceramic bearing has a ball gap on one side. Because of the cageless design, it can load more ceramic balls than bearings with standard structure, there by improving its load capacity. Limitation can achieve the effect of corrosion resistance and temperature resistance of ceramic cage type full wicked ceramic bearing. This series of bearings is not suitable for higher speeds. When installing, pay attention to install the notched surface on the end that does not bear axial load.

Hybrid ceramic bearing

Ceramic balls, especially silicon nitride balls, have the characteristics of low density, high hardness, low coefficient of friction, wear resistance, self-lubrication and good rigidity. They are especially suitable for high-speed, high-precision and long-life rolling bodies with mixed wicked ceramic bearing. For metal. Generally, the inner and outer rings are made of bearing steel (GCr15) or stainless steel (AISI440C). wicked ceramic bearing balls can be made of ZrO2, Si3N4, or SiC.
