In order to make the bearing have the function it should be; avoid premature failure; it must be a must-have for the bearing of the device; it is also necessary to keep it clean.
It is the same as the fine parts; it should be operated when the bearing is installed. In addition; the correct device method is selected; the correct device is used; it is important to extend the service life of the bearing for maximum limit; it is necessary to correctly install the bearing; Generally it seems to be much more handy than the appearance; especially for large-type bearing devices.
TIMKEN bearing installations should be carried out in a dry, dust-free room; away from metalworking equipment or other machinery that produces metal debris and dust. When it is necessary to install bearings in unprotected areas; it is necessary to adopt methods to maintain bearing and device orientation. Free from dust, dirt and moisture; until the end of the device stops. To do this; you can cover or wrap bearings, mechanical parts, etc. with wax paper or foil.
Before the installation; all necessary parts, things, equipment and data should be prepared. The senior professor of the bearing trading network also recommends you; carefully study the drawings or clarify; determine the correct order of the different parts.
To view TIMKEN bearing housings, shafts, seals and other components planned for the bearing; see if they can be cleaned; especially for screw holes, ducts or grooves, where local cast-in-place bearing housings can be used to have mechanically machined residues. The machined surface should be coreless sand; the burrs should be removed.
To see the dimensional accuracy and shape accuracy of all components in the bearing planning, as long as the associated components meet the necessary accuracy; meet the requirements of the public service; the bearing can reach a satisfactory function. The diameter of the cylindrical shaft and the box seat; Generally, the U-shaped gauge or the inner diameter gauge are used to view in two cross sections and four directions. The conical bearing base is selected by a ring gauge, a special taper gauge or a sine gauge.
The bearings should be stored in the original packaging; only take out at the moment before the device; avoid the intrusion of impurities (especially dust). Under normal conditions; do not need to remove the preservative applied to the new bearing before leaving the factory, just scrub the outer cylindrical appearance and cylinder Holes can be. However; if the bearing will be smooth and will be used at very high or low temperatures; or if the smooth grease is not compatible with the preservative, it is necessary to remove the bearing and carefully dry it. This is done to avoid the effects of suffocating on the smoothness of smooth grease.
If the bearing is contaminated due to improper transfer (such as broken packaging, etc.), the bearing should be removed and dried in front of the device.
When the TIMKEN bearing is removed from the original packaging; if the coated preservative is relatively thick and greasy; the bearing should also be removed and dried. Some large bearings with an outer diameter greater than 420 mm can have this condition. Suitable for removing the scavenger of rolling bearings; containing petroleum solvent and white wax.
If the bearing has been supplied with smooth grease smoothness and has internal seals or shields on both sides, it should not be removed before the device.
