● Introduction
SKF deep groove ball bearings are produced by SKF. Founded in 1907, SKF is headquartered in Gothenburg, Sweden, which is the world's leading supplier of rolling bearings and seals. Its business includes bearing manufacturing and seal production as well as the promotion of bearing-related tools, providing customers with various solutions and services. SKF has 11 factories and many service units in China. We maintain good cooperation with SKF company and can distribute SKF bearings. SKF deep groove ball bearings mainly bear radial load, and can also bear a certain amount of axial load at the same time. At high speed, it can be used to bear pure axial load. Regarding the bearing structure, there are open type, Z type, 2Z type, RS type, 2RS type, RZ type and 2RZ type.
SKF ball bearings are suitable for motors, precision instruments, precision instruments, industrial equipment, automobiles, gearboxes, gearboxes, household appliances, tools and mechanical equipment.
● Bearing Series
The types of the bearings include 6000 series, 6200 series, 6300 series, 6400 series, 61800 series, 61900 series, 62200 series, 62300 series and 16000 series.

● Production Details
◆ Grinding of inner diameter of bearing ring
When grinding the inner hole of the bearing ring, the diameter of the grinding wheel is restricted by the hole diameter, and it is easy to be dull. At the same time, in order to obtain a favorable linear speed, the speed of the grinding wheel spindle needs to be increased. High spindle speed is prone to vibration and other problems. due to the small diameter of the grinding wheel, the diameter of the grinding wheel shaft that fastens the grinding wheel is smaller, and it is a long overhang grinding, the rigidity is very poor, and bending deformation and vibration are prone to occur during grinding, resulting in workpieces. Dispersed size and conical inner hole. in addition, the contact area between the grinding wheel and the workpiece during grinding is larger than that when grinding the outer diameter, resulting in a large amount of grinding, and the coolant is not easy to enter the grinding area, so the machining accuracy and surface roughness of the workpiece are degree is more difficult to control.
◆ Quenching of steel balls
In order to improve the hardness, strength, wear resistance and contact fatigue resistance of steel balls, and to obtain comprehensive mechanical properties such as good elasticity and dimensional stability through tempering, quenching treatment is required.
1. Quenching equipment: The commonly used heating equipment for steel ball quenching are box type resistance furnace, salt bath resistance furnace and drum resistance furnace. Among them, the drum-shaped resistance furnace heats evenly and has stable quality.
2. Quenching process: The heating temperature and heating time must be selected reasonably.
● Bearing Clearance Change Failure
Rolling bearings have strict requirements on clearance, otherwise the specified running accuracy and life will not be achieved. During the working process, the bearing is affected by the change of external or internal factors, which changes the original fitting clearance, reduces the accuracy, and even causes the phenomenon of seizing, it is called clearance change failure.
