Preferred to correctly grasp the rolling bearing parts of the use of mechanical devices, select the appropriate SKF bearing only if. Do it, data and information needed in the following areas:
1, mechanical plant, function and structure
2, FAG bearing use part
3, bearing loads (size, orientation)
4, rotation speed
5, vibration, shock
6, bearing temperature (ambient temperature, temperature rise)
7, the surrounding atmosphere (corrosive, clean, lubricate) bearing arrangement is generally chosen.
With two bearings are bearings are radial and axial support, at this time, the side is called a fixed-side bearings, which bear both radial and axial load, fixed relative axial displacements between shaft and housing. Call free on the other side, only take radial loads, axial can be relatively mobile, as a solution to scale axis due to the temperature change problems and install the bearing interval error. For a fixed-side bearing, select scroll available in axial movement (such as cylindrical roller bearings) or to assemble the movement (such as radial ball bearing) bearing. On the short axis, fixed and free sides had virtually no other cases, using only unidirectional fixed axial movement of the bearing (such as radial thrust ball bearing). Selection of bearing type when choosing the NSK bearing type, conditions of use for complete control of the bearing is vital.
