| Huizhou bearings are designed with different bearing materials according to different engineering conditions. Users should comprehensively consider various factors such as the bearing's operating temperature, bearing surface pressure, linear speed, wear resistance requirements, motion type, installation situation, and bearing cost when using and designing the bearing. |
| PV refers to the sum of the products of bearings under certain load and linear speed conditions. The PV value of the equipment is inversely proportional to the service life of the bearings. Therefore, it is recommended to use a lower safe PV value when designing the PV value of the equipment to ensure better service life of the bearings. At the same time, it is also necessary to consider that the actual bearing line speed, operating temperature, etc. on the equipment should not exceed the limit value of the selected material, and should be kept as small as possible. |
Bearings should be cleaned with kerosene or diesel before assembly, and then soaked in oil and pressed dry in engine oil. When assembling bearings and seat holes, it is necessary to keep the bearings from rotating or moving axially in the seat holes, and ensure that the outer surface of the bearings is in full contact with the seat holes. Generally, the contact area should be greater than 70% to facilitate the bearing surface to be copper backed. The friction coefficient between steel and steel is greater than that between copper and plastic. Therefore, a lighter fit is used to ensure that the sleeve does not move relative to the seat holes during use, and that the outer diameter of the sleeve is not too rough, causing significant deformation of the inner hole of the sleeve. For situations with high work pressure, in order to avoid the outer circle of the shaft sleeve, the following two methods are recommended:
1. Increase the outer diameter of the shaft sleeve and correct the deformation of the inner hole with a correction rod.
2. During installation, apply ZY801 anaerobic adhesive to the seat hole to enhance the bonding strength between the shaft sleeve and the seat hole. For bearings with an outer diameter of<50mm, use a pressure head bearing with a handle as shown in the diagram, operate carefully, and gently press into the seat hole. When the outer diameter of the bearing is greater than 55mm, use a handle with a shoulder, a "0" ring, and an auxiliary ring to carefully operate and press the bearing into the seat hole as shown in the diagram.
