Many customers don't know how to install the ceramic bearing when getting it. And dare not to play with it because it is fragile. In fact we needn't worry too much, as long as we can be more careful we can avoid these problems. Below I will give some suggestion about the installation of ceramic bearing.
First of all, we must ensure the average pressure around the ring when embedding the ring to the bearing, be sure don't use hammer to knock on the ring direction to avoid destroying the bearing. In addition it is undesirable if we input one side of the ring which tends to cause indentation. It is better to use rubber hammer to knock the round of the ring.
Another way is to put the ring into the warm water for a while for lubrication, this way is suitable when the working environment of the bearing is out of oil. We can add some lubricating oil for better installation if the oil has no impaction on the equipment.
The last method is very simple, it is according to the tolerance to install. It will be more convenient for us to install if we know the tolerance range of the bearing. So it is better for us to ask for the tolerance range when purchase the ceramic bearing.
Ceramic bearing is expensive and need more careful when installed. Installation methods above are for reference only. Hope we can discus together for better methods.
PS:A Classic Joke about Ceramic Bearing
This week our department carried out a training course on ceramic bearings. After the training our manager told us a joke aboutceramic bearings, but we didn't laugh because didn't understand. Now I tell the story to you, test your ability to understand, it means you are very clever if you laugh after reading it. A brief introduction of our training content. First: the material of ceramic bearings.
(1)ZrO2 resistance to high temperature 270-450 degrees.
(2)Si3N4 resistance to high temperature 400-700 degrees.
(3)SiC resistance to high temperature 700-1200 degrees. Second: the characteristics of ceramic bearings.
(1)Resistance to high temperature 180-1200 degrees, compared with
general steel (-20-120 degrees).
(2) High hardness.
(3) Corrosion resistant.
(4) Natural lubrication, don't need oil to lubricate.
(5) Full ball bearing speed relative.
(6) Because the bearing cage can't work under the temperature of 270 degrees, so the ceramic bearing is designed for full bearings (cage in above 270 degrees will melt and can lead to bearing lock)
Let's enter our joke:
A customer wants to buy our bearings, requirements are as follow:
(1) resistance to high temperature of 350 degrees.
(2) don't require high speed.
(3) need self-aligning ball bearings.
