The radial runout of the sets of the rolling bearing outer ring of the the Kea outer ring in a different angular position, the maximum and minimum radial distance from the outer diameter of appearance and relative to the inner ring between a fixed differential. The angular position of the point or Sakon both sides move at the bearing should be on the inside, the outer ring raceway or the back of the inner ring wall (tapered roller bearings) face contact with the bearing parts in the normal relative position.
The assembled bearing inner ring side facing the beating Sia inner ring raceways in a different angular position, the radial distance from the inner ring axis line that is the inner ring raceway contact diameter of the half, the end face of the inner ring basis Relevance outer ring the difference of the maximum and minimum axial distance between a fixed point. The inner and outer raceway should all move relative to the contact.
The complete set of rolling bearing outer ring side facing the Sea beating outer ring raceways in a different angular position, i.e. the radial distance from the axis line of the outer ring is the outer ring raceway diameter of the semi-contact at the base end surface of the outer ring and the associated the difference of the maximum and minimum axial distance between the inner fixed point. The inner and outer raceway should all move relative to the contact.
Installation, use brute force, a direct hit with a hammer bearing maximum damage to the bearing; cause deformation of the main reasons.
Installed in place, deviation, or not attached to the bearing position, causing the bearing clearance is too small. Inside and outside the ring is not in the center of the uniform rotation, resulting in different heart.
Recommendation: Select the appropriate or professional bearing installation tool installed to use special detection equipment.
According to the survey, the poor lubrication is one of the main cause premature bearing damage. The main reasons include: not timely filling of lubricants or lubricants; lubricants or lubricants are not filling in place; improper selection of lubricants or lubricants; lubrication inaccurate.
Recommendation: select the exact lubricant or lubricants, the use of accurate lubrication filling.
Pollution can lead to premature bearing damage, pollution means there is dust, metal shavings from entering inside the mill bearings. The main reasons include: bearing packaging prior to use to open prematurely, causing pollution; dirty work environment, causing pollution; bearing dirty work environment, the working medium pollution.
Recommendation: best before use Do not disassemble the bearing packaging; keep the installation environment clean installation, clean the bearings to be used; enhance the bearing sealing device.
Fatigue damage bearing common damage. Common reason for fatigue damage may be: bearing long-term overload operation; was not timely maintenance; improper maintenance; equipment aging.
Sets rolling bearing inner ring radial runout of the a Kia inner ring in a different angular position, the inner bore of appearance and the maximum and minimum radial distance between a fixed point relative to the outer differential. In the angular position of said point, or move the body in its Sakon sides at the inner and outer ring raceway or the opposite inner wall (bearing) and the inner surface of contact with the bearing parts at a normal relative position.
