You can check the EDA bearing bearing imports is with the unexpected loads and installation error is large, and be held bearing loss for clues to the cause of.
If there is no choice errors and correctly used, prior to bearing life, but for a long time, in this case, the damage to split. On the other hand, there are early injury by accident, and stand up to use an early injury, as the reason for the early damage, use and consider lubrication is not enough, then there is foreign intrusion, bearing assembly errors and the deflection of the shaft, research on the shaft and bearing box is not enough.
(1) since the groove and slot so that the lubricating oil film thinning or damage, leading to EDA bearing bearing imports local wear; (2) due to the installation between the axis deflection, load partial load, bearing steel back and bearing seat hole with a hard point and oil, shaft or bearing stiffness is not caused by the abnormal wear sliding bearing; (3) foreign body into the bearing surface between the foreign body, when more than the minimum oil film thickness, destruction of oil film, causing wear occurs; (4) the oil volume is too small, low oil pressure caused by the oil shortage or disruption, unable to establish the normal oil film, causing direct contact between the shaft and the bearing metal, cause abrasion or fever; (5) due to improper assembly, so that the bearing and the bearing interference fit is poor, bearing cover dislocation, oil hole position deviation, the shaft and the bearing center line deviation, resulting in loose bearing, bearing and bearing seat hole made contact fretting or incomplete, causing the bearing wear and flaking; (6) the degree of poor bearing interference. No interference causes the bearing steel back and the bearing seat to generate relative motion, causes the steel outer flank wear; the amount of interference, EDA bearing imports bearing bore down, not easy to form the oil film, causing premature wear and even killed.
(1) establish scientific maintenance system. Regular maintenance lubrication system, periodically check the oil pump, filter, the cooler, the quality indicators, the regular and comprehensive determination of lubricating oil quality by oil; (2) the appropriate choice of lubricant, using a fine mesh filter purpose; (3) before the assembly will lubricating thoroughly cleaned, installed to avoid into foreign body. To ensure the bearing sealing and pipe sealing in good condition, keep the oil filter and efficient working condition; (4) the design improvement of the oil groove and hole position, optimize circuit, ensure the normal oil, prevent oil leakage; (5) foreign body to improve assembly process, select the appropriate bearing interference, completely remove EDA bearing import bearings back and other assembly parts.

EDA bearing bearing imports a rotation, inner ring and outer ring raceway surface, due to contact with the rolling scrolling, and running track to the dark side, the running track of the raceway surface does not belong to abnormal, this variable can tell the load conditions, so in the remove bearing case, please strict careful and observation. The running track. If you look closely at the track, it will learn that only bear radial load, axial load, bearing the load torque, or extreme rigidity is not equal in the bearing box.You can check the EDA bearing bearing imports is with the unexpected loads and installation error is large, and be held bearing loss for clues to the cause of.
