Precautions for the Usage:
(1) Keep eccentric bearings and their surrounding environment clean.
Even if the invisible smile dust enters the eccentric bearing, it will increase the wear, vibration and noise of the eccentric bearing.
(2) Users must take care during installing and using.
Strong punching is not allowed, hammers are not allowed to directly hit the eccentric bearing, and pressure is not allowed to pass through the rolling elements.
(3) Use appropriate and accurate installation tools.
Try to use special tools, while avoid using cloth and short fibers.
(4) Prevent the rust of the integral eccentric bearings.
When picking the integral eccentric bearing directly by hand, wash away the sweat from your hands and apply high-quality mineral oil before operating. Pay special attention to rust prevention in the rainy season and summer.
