INA Bearing Jarring and Its Control Methods

Bearing jarring is the sound of metal friction that cylindrical roller bearings on all occasions may occur, and most occurred in grease lubricated large type INA bearings. It's more likely to happen specially in lubricating grease which the base oil performance deteriorated.In addition, it happens more easily in winter. When bear pure radial loads, when the radial clearance is large, the occasion is also easy to occur.And with the different sizes of models, it will occur at a particular speed range easily , and can be both continuous and intermittent.Taking special processing method on outer ring raceway can prevent jarring appearance. When necessary, you can choose this type INA bearing, or reduce the radial clearance of the bearings appropriate, use excellent performance lubricating grease, or improve the bearing matched mechanical parts's rigidity.
