Bearing types, types and sizes vary. In order to make the mechanical equipment perform as expected, it is crucial to choose the most suitable SKF bearing.
The selection of bearings that require analysis is due in many ways, from research, evaluation procedures, to bearings with special specifications, but usually in the following order:
(1) Master the conditions of use of mechanical devices and SKF bearings
(2) Clear requirements for bearings
(3) Type of selected bearing
(4) Selected bearing configuration
(5) Selection of bearing size
(6) Selected bearing size
(7) Method of installing selected bearings
Bearings using conditions and environmental conditions
Under the premise of correct use and the conditions of the mechanical equipment and the SKF bearing area used under the environmental conditions, select the appropriate bearing. Who, to get the following data and information:
(1) Function and structure of mechanical equipment
(2) Site use of SKF bearings
(3) Bearing load (size, direction)
(4) Rotation speed
(5) Vibration, shock
(6) Bearing temperature (ambient temperature, temperature rise)
(7) Ambient atmosphere (corrosive, clean, lubricated)
Bearing configuration options
Typically, the two shaft bearings are supported radially and axially, and this time, the square is called the fixed-side SKF bearing, which bears the effect of the relative axial displacement of the fixed shaft and the bearing housing 2 radial and axial loads. The other side is the so-called free aspect, which only bears the radial load, the axial direction can be moved relatively, the temperature change caused by this solution changes the heading of the telescopic shaft and the spacing error of the mounted bearing.
For fixed-side bearings, the rolling surface can be selected for axial movement, such as cylindrical roller bearings or assembly moving (such as radial ball bearings) bearings. On the shorter axis, the fixed side and other cases have no side effects, and only one one-way fixed axially moving bearing (thrust ball bearing, such as the heart) is used.
