What are the steps to use ball bearings?

Deep groove ball bearings are mainly used to carry radial loads, but when the radial air of the bearing is increased, it has a certain performance of angular contact ball bearings and can accommodate combined radial and axial loads.

Why is the radial clearance of deep groove ball bearings so important?

What should be considered before installing the ball bearing?

(1) The cleaned ball bearing should be inspected. The bearing should be free of damage, rust and flexible rotation without abnormal noise. Check the conformity of bearing type and size, pin and bearing seat, and do not install it until the requirements are met.

(2) During assembly, the pressure applied to the ball bearing should be evenly distributed and perpendicular to the end face, and it is forbidden to be loaded on one side. Select the force point according to the mounting relationship. When the bearing is mounted on the pin, the pressure should be applied to the inner ring of the bearing.

What should be considered when installing the ball bearing?

1.When mounting, the bearing and shaft shoulder should be close together. The clearance between the tapered roller bearing and the radial pressure bearing and the shaft shoulder should not be greater than 0.05 mm, and the other bearings should not be greater than 0.1mm. The bearing cover and retaining ring shall lie flat and evenly against the bearing face and the clearance shall be adjusted in accordance with the technical documentation;

2.When assembling, try to put the end of bearing marked with specification outwards to facilitate inspection and replacement. After assembly, turn by hand to check if it jams, and then grease accordingly. The sealant must be assembled as required and no oil shall leak after sealing;

3.For single row, double row and four row tapered roller bearings and radial bearings, the axial clearance should be checked during assembly and adjusted according to bearing standards or technical documentation.

What should be considered after installing the ball bearing?

All types of radial bearings, needle bearings and angular roller bearings of ball bearings must rotate flexibly after assembly. After assembling the bearing with grease, 65% to 80% of the cavity volume of clean grease is injected into the bearing cavity. Bearings lubricated with thin oil must not be greased.

After installing the ball bearing, the axial clearance to be adjusted and the axial preload (axial preload) should comply with the bearing standards or the technical documentation of the equipment.

Why is the radial clearance of deep groove ball bearings so important?

The radial clearance of deep groove ball bearings is divided into original clearance, installation clearance and working clearance. Usually, the original radial clearance of the bearing is larger than the clearance of the bearing during operation. Clearance is an important technical parameter of the bearing, which directly affects the technical performance of the deep groove ball bearing, such as load distribution, vibration, noise, friction, service life and mechanical motion accuracy. Strictly speaking, the dynamic load rating of the bearing varies with the size of the clearance. The load ratings (C and C0) listed in the catalog are the load values with zero operating clearance. If the clearance is too large, the bearing area inside the bearing will decrease, the stress on the rolling contact surface will increase, the motion accuracy of the bearing will decrease, the vibration and noise will increase, and the service life of the bearing will be shortened. It will even cause the bearing to "seize" during operation. Therefore, it is very important to select different grades of bearing clearance according to the type of bearing and working conditions.
