What are the precautions for the use of tapered roller bearings
The precautions for the use of bearings are as follows:
(1) Keep tapered roller bearings and their surroundings clean.
Even small dust that cannot be seen by the eyes will have a bad impact on the bearing. Therefore, keep the surrounding clean so that dust will not invade the bearing.
(2) Use with care.
When the tapered roller bearing is strongly impacted in use, it will produce scars and indentation, which will become the cause of the accident. In serious cases, it will crack and fracture, so we must pay attention to it.
(3) Use proper operation tools.
Avoid replacing with existing tools, and appropriate tools must be used.
(4) Pay attention to the corrosion of tapered roller bearings.
When operating the bearing, the sweat on the hand will become the cause of rust. Pay attention to operate with clean hands, and it is best to wear gloves as much as possible.
