Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it is only subjected to radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. The friction coefficient of the deep groove ball bearing is very small and the limit speed is also high.
What material are deep groove ball bearings made of?
How are deep groove ball bearings installed?
What is the application field of deep groove ball bearing?
Most deep groove ball bearings are made of special steel. The rings and rolling elements are made of high carbon chromium bearing steel (gcr15 and gcr15simn and zgcr15 and zgcr15simn), and the hardness of the parts is as follows: The rings and rollers made of gcr15 and zgcr15 materials are hrc61~65, and the steel balls are hrc62~66; The rings and rollers made of gcr15simn and zgcr15simn materials are hrc60~64, and the steel balls are hrc60~66. Bearings made of high carbon steel chromium bearing steel are generally suitable for operating temperatures ranging from -40 to 130 degrees, and oil and grease lubrication is normal. It can meet the requirements of general machinery. After the parts of deep groove ball bearings are tempered at high temperature, the working temperature can be up to 250 degrees. With the advancement of smelting technology, different smelting methods can be used for high-carbon chromium bearing steel, such as vacuum smelting technology, which can greatly reform the inherent quality of steel, especially the oxygen content in steel and its non-metallic inclusions. significantly reduced. The fatigue life of bearings made of this high carbon chromium bearing steel can be doubled.
Whether the deep groove ball bearing is installed well or not will affect the precision, life and performance of the deep groove ball bearing. Therefore, please fully study the installation of the deep groove ball bearing, that is, please install the deep groove ball bearing according to the operating standards including the following items.
1. Cleaning deep groove ball bearings and related parts
For grease-lubricated deep groove ball bearings and oil seals or dust caps on both sides, deep groove ball bearings with sealing rings do not need to be cleaned before installation.
2. Check the size and finishing of related parts
3. Installation method
The installation of the deep groove ball bearing should be determined according to the structure and size of the deep groove ball bearing and the matching nature of the deep groove ball bearing parts.
Deep groove ball bearing has the advantages of simple structure and convenient use. It is a kind of bearing with the largest production batch and the widest application range. It is widely used in automobiles, household appliances, machine tools, motors, water pumps, agricultural machinery, textile machinery and many other fields. Its output accounts for more than 70% of the total output of bearings. It is the bearing with the highest output, the most common use and the cheapest price in the world.
SHANDONG CHIK BEARING CO., LTD is known internationally for its excellent quality, sophisticated design, and constant innovation of deep groove ball bearing production technology.
