Structural features of 6218 2rs deep groove ball bearings

6218 2rs deep groove ball bearing inner and outer ring raceways are arc-shaped deep grooves, and the radius of the groove is slightly larger than the radius of the ball. Mainly used to bear radial load, but also can bear certain axial load. When the radial clearance of the bearing is enlarged, it has the function of angular contact ball bearing, which can bear larger axial load and is suitable for high-speed rotation. The bearing can still work normally when the housing hole and the shaft are relatively inclined 8'-16', but its service life will be affected. This type of bearing can be used to bear pure axial load when the speed is high and thrust ball bearings are not suitable.

Compared with other types of bearings of the same size, the 6218 2rs deep groove ball bearing has a small friction coefficient, low vibration and noise, high limit speed, and high precision. It is the preferred bearing type for users when selecting models. However, this type of bearing is not resistant to impact and is not suitable for heavy loads.

6218 2rs deep groove ball bearing is simple in structure and easy to use. It is the bearing with the largest production batch and the widest application range. It is widely used in many fields such as automobiles, home appliances, machine tools, motors, water pumps, agricultural machinery, textile machinery and so on. Its output accounts for more than 70% of the total output of bearings, which is the highest output, the most commonly used and the cheapest type of bearing in China.

6218 2rs deep groove ball bearing is the most common type of rolling bearing. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of retaining structures. Its structure is simple and easy to use. It is the most commonly produced and most widely used type of bearing.

6218 2rs deep groove ball bearing mainly bears radial load, but also can bear radial load and axial load at the same time. When it only bears radial load, the contact angle is zero. When the 6218 2rs 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 6218 2rs deep groove ball bearing has a small friction coefficient and a high limit speed.

6218 2rs deep groove ball bearings can be used for gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, yo-yo, etc.

6218 2rs deep groove ball bearings are mainly used in machinery to support and reduce friction, so the accuracy and noise of deep groove ball bearings are directly related to the use and life of the machine. However, business personnel often encounter some customers, even if they use the best deep groove ball bearings or imported deep groove ball bearings, the efficiency is not high, which is related to the use and selection of deep groove ball bearings. Some people may say that the use and selection of deep groove ball bearings are the user's business, and I only care about what the user wants and I sell. However, as a qualified salesperson, in addition to being proficient in product knowledge, he must also be proficient in the use of products, that is, doctor-type sales, and choose the best supporting deep groove ball bearings according to the performance and use conditions of the user's supporting products.
