How to install the roller bearing block?

Install the bearing should be carried out in a dry, dust-free area, and should be far away from equipment can produce metal debris and dust. When must be installed in a complex environment, should be to minimize pollution.

Cylindrical bearing installation

Cold installationCooperate with not too tight little roller bearing block installation, can be through a sleeve (figure 5, figure 6), and by hammering method, tapping the sleeve bearing is put into place. Should as far as possible even when knock the effect on the bearing ring, in order to prevent the bearing tilt or skewed.

Most of the bearing pressure into the method for installation. If you would have a bearing inner and outer ring loaded on the shaft and roller bearing block at the same time, must ensure that the same pressure effect on the outer ring, at the same time, and must be installed with the tool interface on the same plane.

Heat installation

Normally, for larger roller bearing block installation, not by heating the bearing or bearing is impossible, because with the increase of the size, the greater the force needed for the installation. Heat installation needed between the bearing ring and the shaft or housing, the interference temperature mainly depends on the quantity and the diameter of the bearing fit place. Open type roller bearing block heating temperature shall not exceed 120 ℃, bearings with seals and dust cover is not recommended be heated to above 80 ℃ (shall ensure that the temperature does not exceed seals and grease allowed temperature)Bearing heating, uniform heating, never can have local overheating.
