When agencies operate, install FAG bearing parts to allow a certain temperature, when the stroking mechanism housing should not feel hot to normal, otherwise it indicates that the tapered roller bearing temperature.

High bearing temperatures reasons: oil quality does not meet the requirements or deterioration, lubricating oil viscosity is too high; institutional assembly too tight (lack of space); tapered roller bearing assembly tight; bearing ring is rotated on the shaft or housing ; overload; FAG rolling element bearing cage or fragmentation as well.

Rolling allow a slight noise at work, if the noise is too large or unusual noise or crash, then the bearing is faulty.

Rolling noise is more complex reasons, one is the bearing inner and outer rings with surface wear. Because of this wear, damage to the bearing and housing with tapered roller bearings and shaft relationship, leading axis deviation from the correct position, the shaft produce abnormal sound in the high-speed movement. When the bearing fatigue, its surface metal flake, but also make FAG bearing radial clearance increases abnormal sound. In addition, lack of bearing lubrication, the formation of dry friction, and bearing broken, etc. will have an unusual sound. After the tapered roller bearing wear Songkuang loose cage damage, it will produce abnormal sound.
