Cross cylindrical roller bearing

Cross cylindrical roller bearing friction vibration often have a direct relationship with the grease properties. When the grease performance is not good or not clean, then prone 

to friction vibration, but also with the rolling bearing raceway machining quality, if this processing method is adopted for special precise, can better control the friction

Vibration. Crossed roller bearing vibration basically is caused by the vibration of bearing rings, and the bearing structure, rigidity, precision manufacturing, installation 

conditions and usage and other factors. If the bearing inner race with radial of the ripple of the inner ring road, outer ring rotation axis will produce radial vibration. Cross 

rolling

Corrugated bearing inner ring will not only cause the radial vibration of the outer ring, and

Also by the axial vibration of bearing outer ring, will make the axial bearings, the relative position change under axial load, therefore the thrust in the inner rotating 

cylindrical roller bearing outer ring also produced axial vibration export shaker at work, for bearing high speed rotation, because the ripples caused by moving the frequency, 

there may be equal to the rotational frequency of vibration exciter shaft, which produce

Resonance.

One, keep the bearings and the surrounding environment clean even the eyes can not see the tiny dust entering the bearing, can also increase the cross roller bearing wear, 

vibration and noise. Bearing and its peripheral accessories should be kept clean, especially the dust and dirt, tools and working environment must be kept clean.

Two, use the installation carefully do not allow powerful punch, do not allow the use of hammer percussion, direct bearing, not allowed to pass through the rolling pressure.

Installation tool three, use the appropriate, accurate as far as possible the use of special tools, the use of fabric and fiber or something to avoid.

Four, to prevent the corrosion of bearings directly by hand to take bearings, should wash hands sweat, and coated with high quality mineral oil before operation, during the 

rainy season and summer with particular attention to anti rust. However, in some special operating conditions, the bearing can have a longer life expectancy in traditional 

computing, especially in the light load conditions. These special operating conditions, when the rolling surface

(raceway and roller may cause surface damage) is a lubricating oil film to effectively separate and limit pollutants. In fact, in ideal conditions, the so-called permanent 

bearing life is possible.‍
