Bearing Life Calculation

Check out our 'Bearing Life Calculation Tool' at LILY Bearing. This tool helps you figure out how long bearings will last by considering their type, load, speed, and how they're lubricated. It's easy to use and helps make sure your equipment runs well for a long time. Give it a try for better decision-making on bearings.

The bearing life calculation is specifhically for deep groove ball bearings, including miniature and thin section bearings.

Error

1. Axial load should be less than 25% of the static rated load.

2. Radial load should be less than the static rated load.

Calculator Results
L10 Basic Rating Life

Remarks

1. This life calculation takes 90% reliability

2.This life calculation is valid below 160 degree Celsius

3.This life calculation is not suitable for the working condition of low speed, i.e. the pitch diameter (mm)*speed (rpm)<10000.
