What are the SKF bearings clearances

What are the SKF bearing clearances?

C1 C2 CN C3 C4 C5 CN is a common group oil clearance, usually used only for certain letter combinations to indicate a narrower or offset oil clearance range.

Second, the simple introduction of bearing clearance:

Bearing clearance is also known as bearing clearance. The so-called bearing clearance, that is, the bearing is not installed in the shaft or bearing box, the inner ring or outer ring will be fixed on one side, and then make the bearing clearance is not fixed on one side to do radial or axial movement when the amount of movement. According to the direction of movement, can be divided into radial clearance and axial clearance. The size of the running clearance (called working clearance) has an impact on the rolling fatigue life of the bearing, temperature rise, noise, vibration and other properties.

What kind of equipment are c3 grade bearings suitable for?

C3 bearing clearance is radial clearance of centripetal bearings, larger than the standard clearance; C3 bearing clearance is generally used in the speed is particularly high, vibration is particularly large place. Clearance value according to the size of three groups, a group is the basic group (or called ordinary group), small clearance group (C2), large clearance group (C3, C4) ...  Clearance: the clearance of rolling bearings is an important use of characteristics, the size of the clearance, the fatigue life of the bearing, vibration, noise, temperature rise and mechanical operation precision, etc. has a great impact, choose the bearing, that is, to decide the structure of the bearing size, but also to choose the bearing clearance. Used in vibrating screen, vibrating bar, crusher and so on.
