Rolling bearings use environment: choose standard size, accuracy based on the use of parts and conditions of use and environmental conditions, with suitable rolling bearings is to ensure that the premise of rolling bearing life and reliability.
Using the site: tapered roller rolling bearings suitable for radial load to bear mainly radial and axial joint load, usually paired with two sets of rolling bearings, the main hub in the front and rear wheels of the car, active bevel gear differential, reducer and transmission parts.
It allows speed: install the correct, well-lubricated environment, allowing for the rolling bearing limit speed of 0.3-0.5 times. Under normal circumstances, the limit of 0.2 times the speed of most appropriate.
Allows the tilt angle: Tapered Roller Rolling bearings generally does not allow shaft relative to the housing hole tilt, tilt, if any, does not exceed 2 '.
Allow the temperature: under normal load, and lubricant temperature performance, and, under conditions of adequate lubrication, generally Rolling allowed to work under the ambient temperature of -30 ℃ -150 ℃.
Even the small dust of the eyes can not see, will bring to the rolling bearing bad influence. So, to keep the surroundings clean so that dust will not invade rolling bearings.
Care use.
In the reasons given rolling bearing strong impact, will produce scar and indentation of an accident. Severe cases, it will fracture, fracture, and so must be noted.
Using the appropriate operating tool.
Avoid replaced existing tools, you must use the right tools.
Pay attention to the rolling bearing corrosion.
Operation of rolling bearings, the hands sweat will become rusty. Pay attention to clean hands operation, it is best to try to wear gloves.
