Changzhou Kang Hui Bearing Factory stamping bearing routine maintenance:

1.What are the requirements for the installation surface and installation site?

If the bearing has iron filings, burrs, dust and other foreign matter into the bearing will produce noise and vibration during operation, and even damage the raceway and stamping body. Therefore, before installing the bearings, you must ensure that the installation surface and installation environment clean.

2. Must the bearing be cleaned before installation?

Bearing surface coated with anti-rust oil, you must use clean gasoline or kerosene carefully cleaned, and then coated with clean high-quality high-temperature or high temperature grease can be installed to use. Cleanliness of the bearing life and vibration noise is very large. But we want to remind you that: Closed bearings do not need to clean and refuel.

How to choose grease?

Lubrication is important for the operation and life of the bearing. Here is a brief overview of the general principles for selecting greases. Grease from the base oil, thickeners and additives made of different types and the same type of different grades of grease performance vary greatly, allowing the rotation limit is different, be sure to pay attention to the choice. Grease performance is mainly determined by the base oil, generally low viscosity base oil for low temperature, high speed, high viscosity for high temperature, high load. Thickener is also related to the lubrication performance, the water resistance of thickener determines the water resistance of grease. In principle, different brands of grease can not be mixed, and even the same kind of thickening agent grease, additives will be different because of the bad influence each other.

4. In the lubrication of bearings, the more the better oil coated it?

Lubricate the bearing, the grease painted the more the better, this is a common misconception. Excessive grease in the bearing and bearing chamber will cause excessive agitation of the grease, resulting in extremely high temperatures. Bearing the number of filled lubricant to fill the bearing internal space 1/2 to 1/3 is appropriate, high-speed should be reduced to 1 /

How to install and remove?

Do not hammer the bearing end face and non-force face directly. Do not force the bearing evenly by pressing block, sleeve or other installation tools (tooling). Do not install it by pressing force. If the mounting surface is coated with lubricating oil, the installation will be more smooth. If the interference with the larger, should be placed in mineral oil bearing oil heated to 80 ~ 90 ℃ as soon as possible after the installation, strictly control the oil temperature does not exceed 100 ℃, to prevent the tempering effect of reduced hardness and affect the size of recovery. In the demolition of difficulties, it is recommended that you use the removal tool to pull out the same time carefully to the inner ring pouring hot oil, heat will expand the inner bearing, so that it easier to fall off.
