Types of rolling bearings, a variety of types and sizes. To make mechanical devices played out the expected performance, choose the most suitable bearing is critical.
For selected TIMKEN bearings, requires analysis of many, studied from all angles, evaluation procedures regarding bearing selection, there is no special specification, but generally the order is as follows:
(1) the master, such as conditions of use of mechanical devices and bearings
(2) specify requirements for bearing
(3) selection of bearing type
(4) the selected bearing arrangement
(5) the selected bearing size
(6) the selected bearing specification
(7) of the selected bearing installation methods
Bearing condition and environmental conditions of use
Grasping the TIMKEN bearing uses parts of the mechanism and conditions of use and environmental conditions is a prerequisite for selecting suitable bearing. Do it, data and information need to be made in the following areas:
(1) mechanical device function and structure
(2) bearing service parts
(3) the bearing load (size, orientation)
(4) rotate speed
(5) the vibration and shock
(6) the bearing temperature (ambient temperature, temperature rise)
(7) the surrounding atmosphere (corrosive, clean, lubricate)
TIMKEN bearing configuration choices
Typically, axis are two bearings in radial and axial support, at this point, on one side of the bearing is called a fixed-side bearing, which accommodate both radial and axial loads, fixed relative axial displacement between the shaft and the bearing box. Call free on the other side, only take radial loads, axial can be relatively mobile, to address the arising due to changes in temperature interval of the axis scaling problems and install the bearing errors.
For a fixed-side bearing, select available rolling-axial movement (such as cylindrical roller bearings) or Assembly move (such as radial ball bearing) bearing. On the short axis, fixed and free side not other cases, using only unidirectional fixed axial movement of the bearing (such as radial thrust ball bearings).
