(1) F & Z bearing issue uniform and continuous "hissing" sound. This sound by rolling the inner generated by rotating the outer ring, and includes a rotational speed independent of the irregular metal vibrating sound. The general performance of the bearing grease is not enough, should be supplemented. If the equipment down time, especially at low temperatures in winter, sometimes bearing operation will issue a "hissing rustling" sound, which is bearing radial clearance becomes smaller, grease Penetration smaller related. Should be adjusted bearing clearance, replacement cone penetration bigger new grease.
(2) F & Z bearing periodically issued uniform, "Lo ho" sound in continuous "buzzing" sound. This sound is caused by the rolling elements and raceways appear scars, grooves, rust spots caused. Sound speed is proportional to the period of the bearing. Coping bearing replacement.
(3) F & Z bearing issue is not continuous "stalk stalk" sound. This sound is caused by the holder or the inner and outer ring rupture caused. Must stop immediately replace the bearings.
(4) F & Z issued bearing irregular, uneven "Cha Cha" sound. This sound is due to fall within the bearing iron, sand and other impurities caused. Sound intensity is small, there is no contact with the speed. Response bearings cleaned, re-greasing or oil changes.
(5) F & Z bearing emits a continuous irregular "rustling" sound. This sound generally associated with the inner ring and the shaft bearing outer ring fit too loose or too loose with the bearing bore a relationship with a larger sound intensity. Coping with the bearing inspection, identify problems and timely repairs.
(6) F & Z bearing emits a continuous shrill howling. This sound is due to poor bearing lubrication starvation caused friction, or rolling body tight local contact, such as inner and outer ring raceway deflection, bearing inner ring with tight and so caused. Bearings should be checked promptly identify problems, symptomatic treatment.
