Production steps of bearing rings

The most important part of the bearing is the ferrule of the bearing. The ferrule of the imported bearing is very good, the quality is also very good, then how is the bearing ferrule produced? Proceed as follows

1. Forging: If the over-burning, overheating, and internal cracking into mesh carbides occur during the forging process, the toughness and strength of the ferrule will be reduced. Therefore, the processing temperature, circulating heating and post-forging heat dissipation conditions (such as spray cooling) must be strictly controlled. Especially after the final forging of larger varieties of ferrules, the temperature should be above 700 °C, and should not be stacked.

2. Heat treatment: Close monitoring of heat treatment equipment is an important task in the workshop.

Monitor the reliability of the equipment. Important temperature control devices such as instruments and thermocouples must be closely monitored to ensure accurate and reliable measurement data; timely replacement of errors exceeding the standard is strictly prohibited.

3. Monitoring of grinding process: There is no need for grinding burns and grinding cracks in the finished bearing ferrules, especially for the inner ring to be taper. If the ferrule is pickled, it should be fully inspected, and the burned product should be removed. If the burn is not repaired or the repair is unqualified, it should be scrapped. The ferrule with the burned burn is not allowed to enter the assembly process.

4. Marking management: Before the steel is put into storage and before the ferrule is ground, each process must be strictly managed, and the two different materials and products of GCr15 and GCr15SiMn should be strictly distinguished.

Digital Hygrometer Thermometer

The digital hygrometer thermometer can measure the temperature outside the window (using a remote sensor), inside the room, as well as the humidity inside. It is popular in both houses and apartments. The price of an indoor hygrometer is low, which makes it affordable for most people.


There is nothing more straightforward than a model that`s dealing with measuring humidity in your home. However, you should know that you don`t have to opt for a model with outstanding precision, as you would do when shopping for a model that would be a good fit for your humidor. There are, of course, several factors to consider, such as where you want the hygrometer to be installed, or if you need to monitor more than one room.

Real-time alerts could be one thing for which a digital hygrometer will be handy to have around. If you need to monitor specific areas, such as an attic, you will want to know if the conditions change and can affect the conditions in your home. For such a purpose, remote sensors are a must.
