AI Technical Summary
Idler roller bearings are susceptible to dust, moisture, and particulate matter intrusion, leading to wear, seizing, and lubrication failure, which affects the normal rotation and service life of the idler roller.
The mounted bearing is placed outside the machine housing, and a rubber seal is installed between the mounting plate and the pad. The rubber seal prevents dust, moisture and powder from entering the bearing. At the same time, the roller and shaft are fixed by the expansion sleeve to ensure the normal rotation of the roller.
It effectively prevents dust, moisture and powder from entering, avoids wear and jamming of idler roller bearings, extends the service life of idler rollers, and ensures efficient and reliable operation of belt conveyors.
