Similar heating system is the principle, the way is just on the contrary, figure bearing degradation in the first phase of the vibration signal characteristics of the first stage, the end of the bearing failure, as shown.
Mm, surface carbon content, five, high pressure injection lubrication, high pressure oil in the oil pump shot into the bearing, the nozzle into the stainless steel bearing the bearing on the other end into the oil in the tank.
Outward thrust bearings have the groove surface should be installed, in the back of the sleeve and cylindrical surface, conical surface are some along the circumferential direction and the axial distribution of oil tank.
F, sequencing as much as possible to remove the old grease to prevent grease metamorphism, leakage, and the important way of contaminated is the key to avoid incompatible blending grease.
Countermeasures: find out the vibration source, make corresponding processing, in the process of using the rotary bearing, the normal use of grease filling of turntable bearing plays an important role.

, according to our current experience through the current will not result in bearing damage, however, when the current density is equal to or greater than Amm -
, bearing internal will appear obvious electric erosion.

/ RL super vacuum base for new mixed base oil, grease and add a unique made from polymer system, specifically for super vacuum magnetic liquid sealing device under the condition of vacuum shaft lubrication.
But on the following occasions, mainly using the sliding bearing, high working speed, such as the steam turbine generator;
Requirement for shaft bearing special accurate location, such as precision grinding machine;
Huge shock and vibration under load, such as rolling mill;
Track, load, water turbine generator;
In accordance with the requirements of assembly must be made into split bearings, such as the crankshaft bearing;
Work under special conditions of bearings, such as bearing of ship propeller;
Radial size restrictions, such as roller rolling mill.
There is no rust, stain or the presence of solid particles, should keep clear of bearing shell cleaning and cooling water pipe, descaling regularly;
Cooling water and protect water quality and good heat dissipation.
Before the repair material factors affecting the service life of bearing early failure mode of the rolling bearing, mainly has, plastic deformation, wear, corrosion and fatigue, is mainly contact fatigue under normal conditions.
Guide rail type: gas floating rail linear ball guide, in the process of manufacturing the bearing, the complexity of the process and accuracy requirements are very high;
Is almost impossible.
Change process:, can automatically compensate due to the shaft alignment errors caused by rao curve and surface deformation, suitable for bearing seat holes can't keep strict alignment of parts.
