The influence of KOYO bearing seal of quality for use

For bearing seal degree, the main factors influencing the KOYO bearing sealing performance, there are two, processing and manufacturing precision, cooperation between various parts and assembly quality. To solve this problem must be in-depth study of the two. Sealed bearing precision manufacturing: the influence of sealed KOYO bearings, though not clearly indicate the precision of the level of pain tolerance, but should be appropriate P5 class, in the sealed bearing is mainly due to the relative performance of the sealing performance, the accuracy of the analysis of the rotating. Bearing outer ring end face sealing performance is very strong to beat effect, will cause the oil bearing area along the axial frequency repeated inhalation, spit out the grease and dust escape phenomenon dustproof performance increase, due to the intrusion or seal leakage of oil on the lip, axial movement, lead to inhale vomit in alternating across in the process of dissolving fat, grease and dirt, dust, deteriorating even further. Must be connected to the rotation of the dimensional accuracy and improve the precision of processing and other related manufacturing strict tolerance requirements. Roller accessories bearing the life with the rotation of the roller has close relation with the resistance and sealing performance. 1. Regardless of the rotation resistance size, sealed performance is poor, water and dust pollution KOYO bearings after the end of life. The poor quality of the roller used in belt, easy to feel upset, unable to work. Also want to pay a high price. 2. Average 1 n roller rotation resistance, bearing life can reach more than 15 years; 2. 5 - 3 n roller, KOYO bearing life up to 5 years; 5 - 8 n roller, bearing life is no more than 1 year.
