Double Ceramic ceramic motor bearings & lube
Double Ceramic from California have introduced their new ceramic motor bearings as well as their ceramic-infused bearing lube. The first product is focusing on reducing magnetic interference around the motor to maximise electric motor performance. The full ceramic 540 motor Bearing achieves this with the use of Zirconium Oxide balls and races, which has 80 percent less friction than bare chrome steel balls, while also being 40 percent lighter. This results in less centrifugal force on the balls and less heat generation between the balls and races. The bearing also uses a variation of Double Ceramic’s custom moulded PEEK cage, resulting in no magnetic interference in brushless motors, resulting in quicker spool-up and higher RPM. The Full Ceramic motor bearing also contains no shielding, further reducing friction and increasing high RPM capability.
The second product is the Double Ceramic, ceramic coated, 540 motor bearing. Both the inner and outer races are hardened chrome steel, coated with a super slippery and proprietary ceramic coating, resulting in 10-times less friction than DC’s low friction ceramic silicon nitride material. The balls are Silicon Nitride for 80 percent less friction and 40 percent less weight relative to chrome steel. This bearing uses a custom moulded cage designed to retain lubrication and minimise vibration at high RPM. This is further optimised by employing a material called PEEK, an ultra-hard plastic retaining high tensile strength at temperatures as high as 400℉. This means that the cage won’t break down due to the heat created when spinning at high RPM. It also utilises a shield on one side, further reducing friction while still allowing lubrication retention and protection from debris. The third and final product is Double Ceramic’s Dope ceramic-infused bearing lube. It utilises ultra low friction nano-ceramic particles that are infused into a high temperature, solvent free, naturally ultra-low viscosity base oil, allowing the balls in a bearing to ride on the ceramic particles when this lubricant is used. It creates a temporary ceramic coating on the balls to reduce friction. This lubricant can be used on both ceramic and standard steel ball bearings.
