The matters needing attention before and after the installation of cylindrical roller bearing

Cylindrical roller bearing is a kind of important modern machinery and equipment parts. Its main function is to support the mechanical rotator, reduce the coefficient of friction in the process of the movement, and guarantee its rotation accuracy. When installing a cylindrical roller bearing has a set of strict execution request, below is the bearing before and after the installation note: a note 1, before installation, check the bearing have quality problems. The rotation is flexible, carefully check whether there is any defect on surface of bearing parts, such as indentation, burns, cracks, etc. Strictly forbidden to load the parts with quality problems. 2, ensure the installation site clean, keep a foreign body into the bearing inside. 3, to ensure the bearing cleaning, clean no good bearing don't fit. 4, ensure the quality of the seal. Carefully check whether the packing specifications, size is appropriate, if there is a defect or quality issue, related accessories is complete, the cooperate is reasonable. Second, the matters needing attention when installation 1, avoid hard outfit, collision, must ensure that the load bearing gently, bearing and a hole for the small clearance fit, the normal situation should be light on face is loaded, hard hit diagonal loading much more difficult, so that the surface of bearing hole which can hurt even scrapped. 2, bearing inner sleeve must use inductive heating installation, and shall not exceed 120 ℃. It is strictly prohibited to open flame heating disassembling bearing. 3, poor loads, find out the reasons, troubleshooting problems after adoption of reasonable measures, discovered has the problems such as deformation of parts to repair in time, when it is necessary to modify the drawings. 4, in strict accordance with the requirements into adequate, clean grease. 5, installation is found unqualified parts, such as sealing, gland son must strictly scrap or repair, in order to ensure assembly quality meet quality requirements.
