Enter the radial load and the distance to each bearing from the load to calculate the bearing load on each bearing. This calculation is only for a simple two-bearing system with a load in between them, as shown below.

## Bearing Load Formula

The following formula is used to calculate the bearing load acting on two bearings in a radial shaft system.

R1 = L2*P/(L1+L2)
R2 = L1*P/(L1+L2)
• Where R1 and R2 are the radial loads on bearings 1 and 2, respectively
• P is the radial shaft load between the bearings
• L1 and L2 are the distances from the bearings to the radial shaft load

## Example Problem

How to calculate bearing load?

First, determine the radial load acting on the shaft. For this example problem, the radial load is 400 N.

Next, determine the distance from the further bearing to the radial load point. For this problem, the distance is found to be 10 meters.

Next, determine the distance from the closest bearing to the radial load point. This is measured to be 5 meters.

Finally, calculate the bearing load for each individual bearing.

R1 = L2*P/(L1+L2)

= 5*400/(15)

= 133.33 N.

R2 = L1*P/(L1+L2)

R2 = 5*400/(15)

=266.67 N
