How To Install Full Ceramic Motor Bearings

Do full ceramic bearings need lubrication?

No, full ceramic bearings can be run completely dry. They do not need lubrication to run. Ceramic is non-porous, unlike steel, as a result it is virtually frictionless. Because there is no heat buildup and virtually no friction, full ceramic bearings can be run completely dry.

Do you grease ceramic bearings?

Full ceramic bearings do not require lubrication to run. Ceramic is non-porous and as a result, it is practically frictionless. Dry ceramic bearings are an option.

Are ceramic bearings better than steel?

Because ceramic bearings are harder than steel bearings, they are more durable, lasting anywhere from five to 20 times longer. Finally, ceramic bearings are lighter, because ceramic is less dense than steel (silicon nitride, for instance, has a 60 percent lower density than steel).

Do ceramic bearings need to be broken in?

Like has been said, bearings shouldn’t “break-in” (wear down) for at least a few years on good hubs. This holds true for steel and ceramic. Use grease, not oil, unless you have a staff bike tech who will be doing weekly wheel maintenance for you.

What oil do you use on ceramic bearings?

For XD-15, ceramic zero, ceramic hybrid, and stainless steel bearings we use Kluber NBU52. This grease only runs better and smoother with time and is highly resistant to being washed out. It is engineered to stick to the balls and continually be pulled back into the ball path where it is needed.

How do you take care of ceramic bearings?

Full ceramic bearings are maintenance free. However, they can be washed using regular tap water or a standard bearing cleaner product if required. Make sure the bearing is completely dry before replacing it. These bearings do not need lubricant to operate, so there is no need to add an oil or grease at this stage.

Should I clean my ceramic bearings?

You should clean the bearings and the ball retainers. To do so, soak them first and foremost in a de-greasing solution such as acetone or pure alcohol. Leave it overnight to ensure that all the grease have been removed completely. This is the only sign that the bearings are thoroughly cleaned.

What is Ceramic Grease?

Ceramic Grease is a durable, high-quality ceramic grease. It has been specially developed for applications requiring high pressure and temperature resistance. Ceramic Grease is free of silicones and metal, as a result of which the product meets the environmental regulations on the use of heavy metals.

Is Ceramic Grease good?

The grease has excellent lubricating properties and has extremely good thermal stability. The grease retains/regains its consistency even during temporary high temperature peaks (225 °C) which can arise in wheel bearings under heavy braking.

What is a disadvantage of ceramic bearings?

Ceramic bearings have lower load capacities in comparison to metals and are sensitive to thermal shock. Thermal shock is when the temperature gradient within the material causes a differential expansion, which results in an internal stress. This stress can exceed the strength of the material thus forming a crack.

Is ceramic stronger than steel?

Extreme Hardness Surpassing that of Metals The hardness of alumina ceramics is nearly three times that of stainless steel; silicon carbide is more than four times harder than stainless steel. This extreme hardness is one of many unique properties that makes Fine Ceramics “super materials” for modern technology.

Are ceramic bearings fragile?

Yes. Full ceramic bearings have load ratings 25 to 35 per cent lower than steel bearings. As the material is much harder, it is also more brittle. Therefore, when put under too much pressure, ceramic material may crack while steel is more likely to suffer indentations.

Do ceramic bearings last longer?

First, ceramic bearings have lower friction while spinning at high RPM. Second, well-made, high-quality ceramic bearings can have a significantly longer lifespan than the commonly used stock steel bearings that come installed on most production bikes. This is due to the hardness of the bearings.

Can ceramic bearings rust?

The relative hardness of ceramic bearings results in increased durability over comparable steel bearings. Ceramic material does not rust, unlike steel, meaning exposure to moisture is less of a concern, particularly for full ceramic bearings. They require less lubrication and do not suffer from pitting.

Is Lithium grease better than regular grease?

Lithium-complex greases generally possess good stability, high-temperature characteristics and water-resistance properties. The dropping point and high-temperature life of calcium-sulfonate greases are also better, allowing these greases to be used at higher temperatures.

Is silicone oil good for bearings?

Silicone oil isn’t good for bearings. Silicone is not really a lubricant, it’s more for use as a moisture repellent. If you’re talking about a 1/8th car, it’s best to use light grease. It bleeds out of the bearing slowly so dirt doesn’t work it’s way into the bearing as easily and lasts way longer than any oil.

Can ceramic bearings get wet?

Are Ceramic Bearings Waterproof? Nope. Although the ceramic balls will not be affected by rust, the steel casings of each bearing are still vulnerable to the elements.

How do you clean ceramic kart bearings?

To clean the inside of the bearing, simply remove only one side of the exterior shield, shown above. Next, use Mineral Spirits to clean all the dirt out of the inside of the bearings. Then, use Denatured Alcohol to remove the residue left from the Mineral Spirits.

How often should you clean your bearings?

Remember, bearings only need to be cleaned about once every two to three months depending on the environment you are skating in. If you primarily skate inside several times a month but the surface is not cleaned often, you might have to shine up your bearings once a month.

What should I use to clean my bearings?

Acetone, isopropyl alcohol and mineral spirits are all good options. When using solvents, wear gloves and avoid contact with your skin. Use a dish or wide-mouthed bottle as a container to soak the bearings for several minutes, occasionally swirling the bearings around in the cleaner.

How often should you clean your roller skate bearings?

With regular use under normal conditions, you should need to clean your bearings only once every two or three months. If you skate only indoors and the surface is dusty, you may need to clean them a little more frequently—maybe once a month. Note: consider rotating your wheels every time you have them off your chassis.
