Sleek has an important influence on the fatigue life of the rolling bearing and the conflict, wear, temperature rise, oscillation, etc., without normal smoothness, the INA bearing can not work. Analysis of the damage of the INA bearing is indicated by the fact that about 40% of the INA bearing damage is related to poor smoothness. The outstanding smoothness of the INA bearing is therefore a useful way to reduce INA bearing conflicts and wear. In addition, the smoothness of INA bearings also contributes to heat dissipation, rust prevention, sealing, and flat cushioning. To ensure that the smoothing agent does not expire, the selection should be correct. The harvesting machine INA bearing is smooth and oily smooth and grease smooth. The large model gear box oil is smooth and GL-5 80W90 gear oil is used. The grease is smooth and usually uses lithium molybdenum disulfide-based smooth grease, smooth torque increaser and stepless speed change. The lower equipment must be smooth with Mobil XHP222 or better grease; the importance of grease smoothness on bearings can be imagined; the same is true for SKF bearings; the best use of better quality grease; do not use those primary disabilities The grease is smooth; this will create a big problem for our bearings; thousands of SKF bearings are damaged; that loss is not a little bit.
Others: bearing burns and treatment methods; the so-called INA bearing wear burn damage refers to: INA bearing rolling wheel, rolling body and the support frame sharply heated in the rotation until discoloration, softening, welding and damage. Forming SKF bearings The primary cause of burns is because of the poor smoothness of the bearings imported from INA; the use of smoothing agents that are not on track; perhaps too much smoothing agent; too little; all are incorrect. Secondly, it can be excessive load (preload is too large). The speed is too large. The clearance is too small. There is water or other foreign matter intrusion. If the above two conditions are not the case, the accuracy of the shaft, the INA bearing box is poor, and the deflection of the shaft is large.
See here; I think we all want to know the way to deal with; first; to discuss smoothing agent and smooth method; choose INA bearing smoothing agent; and its dosage; and to correct the selection of INA bearing. Discussion cooperation, INA bearing Clearance and preloading; and improve the sealing equipment. Look at the accuracy of the shaft and INA bearing box. Of course, here is an INA bearing for example; in fact, the SKF bearing is also the same; the same will be presented; the treatment is the same.

STAINLESS STEEL PRODUCTS

Stainless steel is a corrosion resistant steel alloy with a minimum of 10% chromium. There are different grades and surface finishes of stainless steel produced to accommodate the environment in which the material will be implemented. Unlike carbon steel, stainless steel does not rust when exposed to air and moisture due to the sufficient amount of chromium present. The chromium creates an invisible passive film of chromium oxide that will not let oxygen attack the surface and prevents rusting of the iron base.

Yuhong Group is a stainless steel manufactory of more than 20 grades of Stainless Steel.
