Radial clearance for bearing is a measured value of the total movement of one ring relative to the other in a plane perpendicular to the bearing axis. It is calculated in terms of minimum film thickness and minimum film thickness variable.
The calculator uses the formula:
Where:
Explanation: This formula calculates the radial clearance by dividing the minimum film thickness by the minimum film thickness variable.
Details: Accurate radial clearance calculation is crucial for proper bearing performance, lubrication efficiency, and preventing premature bearing failure in mechanical systems.
Tips: Enter minimum film thickness in meters and minimum film thickness variable (dimensionless). Both values must be positive numbers greater than zero.
Q1: What is radial clearance in bearings?
A: Radial clearance is the total movement of one bearing ring relative to the other in a plane perpendicular to the bearing axis, which affects bearing performance and lifespan.
Q2: Why is minimum film thickness important?
A: Minimum film thickness is the lowest amount of oil film thickness formed inside sliding bearings, crucial for proper lubrication and preventing metal-to-metal contact.
Q3: What factors affect radial clearance?
A: Manufacturing tolerances, operating temperature, load conditions, and material properties can all affect the actual radial clearance in bearing applications.
Q4: How does radial clearance affect bearing performance?
A: Proper radial clearance ensures optimal load distribution, reduces friction, minimizes heat generation, and extends bearing service life.
Q5: When should this calculation be used?
A: This calculation is essential during bearing design, selection, and maintenance to ensure proper clearance for specific operating conditions and applications.
