Fan bearing box: what are the consequences of 7309 bearing if damaged

Bearing lubricating oil bearing grease synthesized from low viscosity lubricating oil and add the antioxidant, anti corrosion made from a variety of additives such as lubricating oil, designed for powder metallurgy oil bearing lifetime lubrication, sound, temperature range of use: temperature range: - ~ + ℃. The classification of the thrust bearing radial thrust bearing this kind of structure is placed in the body for the radial and thrust bearings, bearing is spherical to match corresponding spherical and bearing sleeve body, make the bearings with to automatically adjust the deflection of shaft deformation, reach on the tile surface and the rotor thrust plate surface, have a good contact between this structure is suitable for flexible rotor and axial load is not too much of a unit. Cage coating fall off or convex bubbles due to cage in front of the silver plating process processes improper, or silver plating process exists some problems, affecting the coating and the decrease of strength of the combination of the parent material, coating defects such as loss caused by work. Bearing lubrication is usually caused by adverse factors include: lubricating oil ( Grease) Inadequate; Oil pipe blocked, etc. ; Lubricating oil ( Grease) There is something wrong with the quality; Add lubricating oil is not on time, Grease) ； Lubricating oil ( Grease) Containing impurities. There is in these factors of the special damage type and damage to leave special marks, such ability when bearing the lubrication for reasonable lubrication effect. Peeling off the seal form changes shaft rotary vibration: fatigue spalling, bearing quality bad rolling bearing parts in the form of point contact and line contact, long-term work under the high alternating contact stress. Abrasive wear work refers to the bearing surface between into foreign hard or metal abrasive dust on the surface of the solid particles or relative movement and the contact surface caused by the wear and tear, often cause furrow of abrasion in bearings working surface. Troubleshooting: please send back to our company for maintenance, the spindle of dismantling check will find axis ( Bearing chamber) Surface scratches, even groove of the shaft or the bearing chamber surface grinding. Swimming bearing usually choose no guard of cylindrical roller bearing inner ring or outer ring ( Prototype, type) Such bearings and needle roller bearings, this basically is the internal structure allows axis and shell have proper axial displacement. Can be used sewing machine oil or spindle oil, bearing temperature is too high, — Culprit here high bearing temperature caused by many reasons, small make up finishing the common several big problems for everyone. Through the introduction of the big blue hydraulic factory, I think we all know, the main factors affecting the service life of gear pump is diverse, and at the end of the day, in addition to affected by the manufacturer manufacturing process, the correct installation and rational use of the gear pump is very important. Overall eccentric bearing outer ring tight fit with the overall eccentric bearing holes, inner ring and the shaft is a loose fit, as a whole can be eccentric bearing pressure into the whole eccentric bearing hole first, then assembling casing diameter should be slightly less than the diameter of a hole.
