The complete sets of the outer bearing race runout Kea outer ring in a different angular position, the difference between the outer diameter of the outer relative to the inner ring a fixed maximum and minimum radial spacing. In the angular position of said point or in the rolling at both sides of its Sakon import bearing body should be provided on the inner and outer ring raceway or the inner surface of the inner ring opposite wall contacting the bearing parts in the normal relative position.
The assembled bearing inner ring side facing the beating Sia inner ring raceway in a different angular position, in the interval from the inner ring radial direction of the axis line equal to the inner ring raceway contact with half of the diameter at the base end and the inner ring associated with the outer ring to a fixed point between the maximum and the minimum axial spacing of the differential. The inner and outer raceways shall be in contact with all rolling bodies.
The assembled bearing outer ring side facing the raceway of the beating Sea outer ring in a different angular position, away from the outer ring of radial direction of the axis line at intervals equal to the outer ring raceway contact diameter at half cup base end and the relevant within ring to a fixed point between the maximum and the minimum axial spacing of the differential. The inner and outer raceways shall be in contact with all rolling bodies.
Installation, use brute force, a direct hit with a hammer bearing on the bearing damage; caused by the deformation of the main reasons for.
Installed in place, the installation of a deviation or not attached to the bearing bit, causing the bearing clearance is too small. Inside and outside the ring is not in the same center of rotation, resulting in a different heart.
Recommendation: Select the appropriate or professional bearing installation tool installed to use special equipment testing.
According to the survey, poor lubrication is one of the main reasons that cause premature bearing damage. Mainly due to: and not timely filling of lubricants or lubricants; lubricants or lubricants are not filling in place; improper selection of lubricants or lubricants; lubrication incorrect.
Recommendation: Choose the correct lubricant or lubricants, use the correct lubrication filling.
Pollution can lead to premature bearing damage, pollution, dust, metal shavings from entering inside the bearing. The main reasons include: bearing packaging prior to use to open prematurely, causing pollution; installation dirty work environment, causing pollution; bearing the dirty work environment, the pollution of the working medium.
Recommendation: best before use packaging; Do not disassemble bearings keep the environment clean install, install bearing cleaning; enhanced bearing the seal device.
Fatigue failure is bearing a common way of damage. Common fatigue failure may be due to: the bearings long-term overload operation; maintenance is not timely; improper maintenance; equipment aging.
Runout of the sets of the bearing inner race Kia inner ring in a different angular position, the inner bore outer the relative outer ring of a fixed point between the maximum and minimum radial spacing difference of. The angular position of said point or at the rolling bodies on both sides of its Sakon and inner, the outer ring raceway or the inner ring the negative wall (bearing) to the inner surface of contact with the bearing parts in the normal relative positions.
