Tapered roller bearings for use in the environment under which


tapered roller Full complement cylindrical roller bearing are precision components, its use should also be carefully carried out. No matter how high-performance bearings, if used improperly, it will not get the expected performance. Use Notes on tapered roller bearings are as follows.
First, keep tapered roller bearings and their surroundings clean
Even tiny invisible dust into the tapered roller bearings, will increase wear, vibration and noise of the bearing. tapered roller bearings and its peripheral accessories should be kept clean, especially the dust and dirt, tools and working environment must be kept clean.
Second, when using the installation to be carefully
Does not allow a strong punch, not allowed to use a hammer, a direct hit  tapered roller bearings are not allowed to pass through the rolling pressure.
Third, the use of appropriate and accurate installation tool
Try using a dedicated tool, try to avoid using fabric and staple fiber stuff like that.
Fourth,  tapered roller bearings to prevent corrosion
Direct hand pick  tapered roller miniature linear bearings  to fully wash hands sweat, and coated with high quality mineral oil and then operate in the rainy season and summer with particular attention to rust. However, in some special operating conditions, the bearing can be obtained in a longer life of traditional computing, especially under light load conditions. These particular operating conditions that, when the rolling surface (track and rolling elements) are effectively separated and limit pollutants may cause surface damage of a lubricant film. In fact, under ideal conditions, the so-called permanent tapered roller bearing life is possible.
Use the site and conditions of use and environmental conditions to select size, precision, with appropriate tapered roller bearings based on the bearing life and viability of the premise.
1, using the site: tapered roller bearings for joint load to bear radial load mainly radial and axial, usually paired with two sets of crossed roller bearings  primarily for automotive front and rear hub, active gear, differential , a reducer and other transmission parts.
2, the permissible speed: install properly oiled environment, allowing for tapered roller bearings 0.3-0.5 times the speed limit. Under normal circumstances, to 0.2 times the speed limit is the most appropriate.
3, allowing the tilt angle: Tapered roller bearings are generally not allowed to tilt axis relative to shell hole, if inclined, to a maximum of 2 '.
4, allowing the temperature: in under normal load, and lubricant high temperature performance, and under conditions sufficient lubrication, tapered roller bearings are generally allowed to work at -30 ℃ -150 ℃ ambient temperature.
