    Bearing different according to the direction of the load bearing, stainless steel bearings mainly take radial load, bearing can withstand can bear radial load and axial load, bearing mainly bear axial load. Bearing under load conditions, is the radial load acting on the shaft, Fr and Fn were acting on the shaft bearing radial load on both ends. Bearing under the action of radial load, bearing and roller contacts inside and outside the circle by pulsating cyclic stress the role of the fatigue pitting, bearing running after reaching a certain time, make the rolling element bearings, inner and outer ring raceway lose its original shape, the axis of rotation accuracy is reduced, the machine vibration and noise increased, resulting in bearing failure.
    Bearing loading situation, Fr and Fn were acting on the shaft radial load and axial load, Fr and Fn were role on the left side of the shaft bearing radial load and axial load, and Fa2 were acting on the shaft right end bearing radial load and axial load. Roller Bearings under the action of radial load and axial load, fatigue pitting occurred not only, and under the action of axial load, end bearing is compact, the other end of the stainless steel bearing is relaxed, contact surface pressure end bearing element, but also produce wear, so to speed up the bearing failure. Bearing under the action of axial load bearing elements inherit the extrusion, therefore in the process of operation and roller contact on inner and outer surface fatigue pitting corrosion and wear. Overload or excessive impact load of rolling bearing damage is very big, will cause the bearing and roller contact point on inner and outer plastic deformation occurs, permanent deformation and bearing component, the bearing life shorten.
    Rotating bearing, should be very smooth without sound, also should not have impurities. Stainless steel bearings allow running noise slightly in the work, if you have any abnormal noise or excessive noise or sound, suggests that the bearing failure. Bearing anti-rust treatment using a slight aroma of anti-rust oil, and the dosage is not big. Make the whole stainless steel bearing clean fragrance. Bearing in the horizontal plane and vertical plane junction with fine chamfering, and has a dark side. Bearing in the process of normal use, installation of bearing parts allowed to have a certain temperature, when the hand touch body shell, should not feel hot as normal. If NTN bearing use process temperature is too high, it can consider lubricating oil quality meets the requirements or metamorphism, the high viscosity of lubricating oil; Or install the assemble tight, bearing assembly too tight; Bearing cage or rolling body fracture, etc.
Bearing noise can be caused by many reasons, one is the bearing inner and outer surface wear. Again, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. Keep the stainless steel bearings and lubrication clean is very important. Need before checking surface cleaning machine, and then remove the perimeter of the bearing parts. Oil seal is very fragile parts, so need to carefully remove, not excessive force, and then carefully check oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace, and bad seal will result in bearing damage and severe equipment downtime.
