6205 zz c3 bearing is used in a variety of machines

6205 zz c3 bearing is used in a variety of machines and equipment with rotating parts. Designers often have to decide whether a ball bearing or a fluid film bearing should be used for a particular application. The following characteristics make ball bearings more desirable than fluid film bearings in many situations.
Bearing clearance for 6205 zz c3
Bearing 6205 zz c3 clearance (internal clearance) refers to the total distance that a bearing ring can move relative to another ring in a certain direction before the bearing is installed with the shaft or bearing box. According to the direction of movement, it can be divided into radial clearance and axial clearance.

The internal clearance of the 6205 zz c3 bearing before installation must be distinguished from the internal clearance (operating clearance) of the bearing when it reaches the operating temperature after installation.
The original internal clearance (before installation) is usually larger than the operating clearance. This is due to the difference in the degree of fit involved in the installation fit, and the difference in thermal expansion of the inner and outer rings of the bearing and related components causes the inner and outer rings to expand or contract.
Selection of internal clearance for 6205 zz c3 bearing:

When selecting the most suitable clearance according to the use conditions, the following points should be considered:
(1) The change of clearance caused by the fit between the 6205 zz c3 bearing and the shaft and the housing.
(2) The change of clearance caused by the temperature difference between the inner and outer rings when the bearing is working.
(3) The materials used for the shaft and the housing affect the change of bearing clearance due to different expansion coefficients.
