Enter the frictional power loss (W), the heat dissipation per degree above ambient temperature (W/C), and the ambient temperature (C) into the Bearing Temperature Calculator. The calculator will evaluate the Bearing Temperature.

## Bearing Temperature Formula

The following formula is used to calculate the Bearing Temperature.

BT = (FL / HD) + Tamb

Variables:

- BT is the Bearing Temperature (C)
- FL is the frictional power loss (W)
- HD is the heat dissipation per degree above ambient temperature (W/C)
- Tamb is the ambient temperature (C)

To calculate the bearing temperature, divide the friction power loss by the heat dissipation per degree, then subtract the ambient temperature.

## How to Calculate Bearing Temperature?

The following steps outline how to calculate the Bearing Temperature.

- First, determine the frictional power loss (W).
- Next, determine the heat dissipation per degree above ambient temperature (W/C).
- Next, determine the ambient temperature (C).
- Next, gather the formula from above = BT = (FL / HD) + Tamb.
- Finally, calculate the Bearing Temperature.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

frictional power loss (W) = 500

heat dissipation per degree above ambient temperature (W/C) = 60

ambient temperature (C) = 25

BT = (FL / HD) + Tamb =** ** ?
