YOCH Bearing

When the inner diameter of the KOYO bearing is greater than 70mm, or the fit interference is large, the heating method is used to expand the KOYO bearing hole, which saves labor and time during installation and avoids damage caused by excessive force.

Powder metallurgy is a processing method that prepares metal powder and makes products from metal powder or a mixture of metal powder and non-metal powder through processes such as shaping and sintering. It can not only prepare special materials that are difficult to prepare by ordinary smelting methods, but also manufacture various products. A kind of precision mechanical parts, saving labor and materials. However, the cost of molds and metal powder is high, and it should not be used when the batch size is small or the size of the product is too large. Compared with traditional material processes

Whether the forklift needle roller bearings are installed correctly will affect accuracy, life, and performance. Therefore, when installing forklift needle roller bearings, it is hoped that they should be installed according to operating standards. Please refer to the following

A Complete List Of Abnormal Sound Factors Of Bearings

After the bearing is installed, in order to check whether the installation is correct, an operation inspection must be performed. Small machinery can be rotated by hand to confirm whether it rotates smoothly. Inspection items include poor operation due to foreign matter, scratches, and indentations, unstable torque due to poor installation and poor machining of the mounting base, excessive torque due to too small clearance, installation errors, and sealing friction, etc. wait. If there is no abnormality, the power operation can be started.

When the bearing rotates at a high speed and bears a large axial load, the end surface of the nut in contact with the inner ring of the bearing should be perpendicular to the rotation center line of the shaft. Otherwise, even if the nut is tightened, the installation position of the bearing and the normal working condition of the bearing will be destroyed, and the rotation accuracy and service life of the bearing will be reduced. Especially when the fit between the bearing inner hole and the shaft is a loose fit, strict control is needed.

The service life and reliability of rolling bearings are closely related to the metallurgical quality of the bearing steel. Due to the characteristics of bearing steel, the requirements for metallurgical quality are much stricter than those of general industrial steel.

According to the size of the load If the load or impact is large, choose roller bearings (line contact); If the load is small or the impact is small, ball bearings (point contact) should be selected.
