Ceramic Bearings Why

Cooler running ceramic bearings have no micro weld adhesion between the balls races which means lower friction.

Ceramic bearings why.

Second ceramic hybrids don t need lubrication. No cold welding or adhesive wear and with lowered centrifugal forces ball skidding is minimized. 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. Thermal shock is when the temperature gradient within the material causes a differential expansion which results in an internal stress.

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. All the tests i have seen test new or just broken in bearings and show that one could save somewhere between 5 and 10 watts for a pulley bottom bracket and wheel bearing upgrade of course mostly depending on your current set up as a starting point. Ceramic bearings have lower load capacities in comparison to metals and are sensitive to thermal shock. Bearings run cooler and vibration levels are lower at high rpm.

Everyone knows that ceramic bearings have less friction than steel and thus perform far better but few may understand why that is. 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. 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. This is because the properties of.

Ceramic also has a lower amount of thermal expansion which also reduces temperatures. Ceramic hybrid ball bearings are electrically non conductive. 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. Longer life ceramic bearings last up to 5 times longer than steel.

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. 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. First ceramic balls will not corrode. Three advantages of the ceramic hybrid ball bearing.

Performance benefits of ceramic bearings. This stress can exceed the strength of the material thus forming a crack.
