What is the clearance of a deep groove ball bearing?
We generally refer to the clearance of deep groove ball bearings as radial clearance and axial clearance.
What is radial clearance?
Radial clearance is the maximum radial movement of the outer ring when the bearing inner ring is fixed.
What is axial clearance?
Axial clearance refers to the maximum axial movement of the outer ring when the bearing inner ring is fixed.
What is the clearance of bearings?
For deep groove balls, the clearance we generally refer to is radial clearance.
What are the parameters for radial clearance?
According to international standards, there are many different clearance combinations. Clearances are arranged in ascending order: C2, C0, C3, C4, and C5.
Bearing C2 Clearance: C2 clearance is smaller than the standard clearance and requires precise matching with shaft, bearing, and machine cover tolerances.
Bearing C0 Clearance: C0 is the standard clearance for deep groove ball bearings and a commonly used clearance grade, suitable for most general operating conditions, such as motors, water pumps, reducers, and other general machinery.
Bearing C3 Clearance: C3 clearance is larger than the standard clearance and is suitable for installations with an interference fit between the shaft, bearing, and housing, in high-temperature installations, such as high-temperature motor bearings, or where thermal expansion compensation is required. It is also commonly used in high-speed applications to reduce internal friction and heat generation.
Bearing C4 Clearance: Slightly larger than C3, it is suitable for heavy machinery with large interference fits and significant temperature differences.
Bearing C5 Clearance: C5 is an extra-large clearance and is only used in a few special applications.
◆In short, clearances from C2 to C5 increase in order. We will tailor the appropriate bearing clearance to the specific application scenario provided by the customer, ensuring they have no after-sales concerns when using our bearings and rollers.
◆There's so much technical knowledge involved in a small ball bearing. Choosing the right clearance is crucial for worry-free bearing rotation. As a Chinese bearing manufacturer, choose us for our expertise and stable bearing quality at competitive prices.
