Ceramic Bearings Why

No cold welding or adhesive wear and with lowered centrifugal forces ball skidding is minimized.

Ceramic bearings why. And the answer to that is relatively simple although multi fold. This stress can exceed the strength of the material thus forming a crack. Cooler running ceramic bearings have no micro weld adhesion between the balls races which means lower friction. When sintered silicon nitride balls are used in ceramic hybrid ball bearings there are many benefits to these advanced ceramics over conventional steel balls including.

Ceramic bearings have lower load capacities in comparison to metals and are sensitive to thermal shock. Second ceramic hybrids don t need lubrication. Thermal shock is when the temperature gradient within the material causes a differential expansion which results in an internal stress. The non conductive silicon nitride ceramic balls in our ball bearings eliminate electrical arcing through the bearing crucial in applications where an electric motor is controlled by a variable frequency drive vfd.

Quality hybrid ceramic bearings are better than steel bearings in a bicycle bottom bracket application because they have rounder balls for lower resistance better races for lower resistance and are grease efficient in low rpm low heat environments for lower resistance. To start ceramic balls do not corrode nor do they cold weld which is the process whereby forms of metals can wear through the adhesion of. Ceramic hybrid ball bearings are electrically non conductive. 5 beyond spalling caused by mechanical overload which is commonly seen in original ims bearings adhesive wear and ball skidding are commonly seen in worn or failing ims bearings.

Because ceramic bearings are rounder with a smoother surface and more uniform size friction is reduced and that can contribute to a less energy required to turn the cranks or spin the wheels. Bearings run cooler and vibration levels are lower at high rpm. Ceramic hybrid bearings have a few distinct advantages says cory oliver head of marketing for the south florida company which he says was the first to market ceramic hybrid bearings to the fishing reel community. According to research a well made ceramic bearing will roll faster saving you energy and allowing faster cruising speeds compared to an equivalent steel bearing.

Everyone knows that ceramic bearings have less friction than steel and thus perform far better but few may understand why that is. Longer life ceramic bearings last up to 5 times longer than steel. Three advantages of the ceramic hybrid ball bearing. First ceramic balls will not corrode.

Ceramic also has a lower amount of thermal expansion which also reduces temperatures. High quality bearings save watts.
