Installation of pulley bearing
Installation of fixed end front bearing on the shaft: thoroughly clean the bearing with clean cleaning kerosene. For grease lubrication, first inject the organic solvent containing 3% ~ 5% grease into the bearing for degreasing and cleaning, and then fill the quantitative grease into the bearing with an oil gun (accounting for 10% ~ 15% of the bearing space volume).
Heat the bearing to raise the temperature by 20 ~ 30 ℃, and install the bearing into the shaft end with an oil press; Press the set sleeve on the shaft and press the bearing end face with appropriate pressure to make it axially positioned; Roll the belt of the spring scale on the outer ring of the bearing and check whether the specified preload changes greatly by measuring the starting torque (even if the bearing is correct, the preload may also change due to bearing the deformation of the fit or cage).
