On the bearing rotating speed, bearing is according to the type of bearing, size, precision, cage type, load, lubrication, and cooling way. Bearing installation and disassembly, in specific applications often need to disassembly and assembly, to ensure that can according to the testing and maintenance. Can be installed separately on inner and outer bearing such as: cylindrical bearings, needle roller bearings, and tapered bearing fits for this occasion. Taper groove of automatic self-aligning ball bearing and spherical roller bearing under the help of shaft sleeve, also simplifies the installation program. Exerted pressure in some cases to rolling bearing in order to increase rigidity, this program is typically used for deep groove ball bearings, angular contact ball bearings and tapered roller bearing inner and outer circle of bias, shaft bending, shaft or the bearing box tolerance changes, cooperate with the mistake could lead to the eccentricity of the inner and outer ring. In order to prevent the eccentric Angle through the large, automatic self-aligning ball bearings, automatic self-aligning roller bearings, or self-aligning bearing seat is a better choice. Voice frequency and torque, move bearing according to produce high precision measure is made, so the voice and the torque is small. Deep groove ball bearings and cylindrical roller bearing used for in low voice, low torque has special requirements of the occasion. ( 1) Note with sealed bearing is clean with this law, sealed internal cleaning should stick to the same. ( 2) Assembly shall be appearance with a clean gasoline, kerosene, toluene and xylene solution clean, and to wipe them with clean cloth, and then coated with a thin layer of smooth oil, which can make the device to operate bento efficiency. ( 3) Encapsulated in the device when open bearing, put it into the liquids such as gasoline with handle gently gently turning, to ensure that insist on frame, rolling element and raceway appearance of encapsulated oil be cleaned completely. ( 4) When cleaning a lot of bearing, with the first temperature is 90 ~ 100 ℃ heat oil pour hot oil to make packaging condensation, at the same time with seamless all mouth and no net exfoliation tools to dig the old oil, then pour hot a few minutes, then rinse with kerosene oil, clean with gasoline again finally. After washing clean, the bearing on film gloves should be worn in the workbench of dry clean cloth or paper.
