NSK bearing selection and considerations for using

Summary of selected types of rolling bearings NSK bearings, types and sizes are varied. Mechanical installations play out for the expected performance, choose the most suitable bearing is critical. For the selected bearing requires analysis of many factors, from every angle to research, evaluation procedures for selection of bearing, no special specification, but the General sequence is as follows:
(1) master the use of mechanical devices and bearing condition
(2) specifies the requirements for bearing
(3) the type of the selected bearing
(4) select the bearing arrangement
(5) the selected bearing size
(6) the selected bearing specification
(7) installation method of NSK bearing used for the selected bearing correctly grasp the bearing condition and environmental conditions in the use of mechanical devices and the conditions of use and environmental conditions is a prerequisite for select suitable bearing. Do it, data and information needed in the following areas: (1) mechanical device function and structure
(2) bearing service parts
(3) the bearing load (size, orientation)
(4) the rotation speed
(5) the vibration and shock
(6) the bearing temperature (ambient temperature, temperature rise)
(7) the surrounding atmosphere (corrosive, clean, lubricate) bearing selection of configuration modes
Typically, the axis is based on two bearings in 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, to address arising due to temperature change of interval error of the telescopic part of the shaft and bearings. 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).
