Bearing type, type and size different. In order to make mechanical equipment play expected performance, to select the most appropriate SKF bearing is very important.

Selected bearing, need analysis is because many, from every Angle, research, the assessment process, with special specifications of bearing no choice, but usually in the following order:

(1) control of the machine equipment and the use of bearing SKF conditions

(2) bearing clear requirements

(3) the selected the type of bearing

(4) selected bearing configuration

(5) bearing size selection

(6) the selected bearing size

(7) selected bearing installation method

Use condition and the environmental condition bearing
Correct understanding and mechanical equipment use conditions and environment conditions of use SKF bearing area, under the premise of choose appropriate bearing. Who, to get the following data and information:

(1) mechanical equipment of function and structure

(2) SKF bearing site use

(3) bearing load (size, the direction)

(4) rotation speed

(5) vibration and impact

(6) bearing temperature (environment temperature, temperature rise)

(7) the surrounding atmosphere (corrosive, clean, lubrication)

Bearing configuration options
Usually, the two shaft bearing radial and axial support, this time, party called fixed side SKF bearings, it under the fixed axis and bearing axial displacement of the relative box of 2 role radial and axial load. The other side is the so-called freedom, only bear radial load, axial can relative motion, this solution has the temperature change of the shaft of the title and the expansion of the bearing interval installation error.

For fixed side bearings, rolling surface can choose in axial movement, such as cylindrical roller bearing or assembly mobile (such as centripetal ball bearing) bearing. In short axis, fixed side and other cases no side effect is small, with only a one-way fixed axial moving bearing (thrust ball bearings, such as a heart).
