Bearing Load Calculator
Calculate bearing life and load capacity based on operating conditions
About this calculator
The Bearing Load Calculator determines the expected service life and load capacity of rolling bearings under specific operating conditions. This essential engineering tool helps mechanical engineers, maintenance professionals, and designers select appropriate bearings for their applications and predict when replacement will be needed. By analyzing factors like applied loads, rotational speed, and bearing specifications, it prevents premature failures and optimizes maintenance schedules, ultimately reducing downtime and operational costs in mechanical systems.
How to use
Enter your bearing's basic dynamic load rating, applied radial and axial loads, and operating speed in RPM. Select the bearing type and input any load factors for your specific application conditions. The calculator will compute the expected bearing life in hours and determine if the current loading is within safe operating limits.
Frequently asked questions
What is L10 bearing life?
L10 life represents the number of operating hours that 90% of identical bearings will complete before showing signs of fatigue failure under specified conditions.
How does speed affect bearing life?
Higher rotational speeds reduce bearing life exponentially. Doubling the speed can significantly decrease expected service life due to increased stress cycles and heat generation.
What factors reduce bearing load capacity?
Contamination, inadequate lubrication, misalignment, extreme temperatures, and vibration all reduce effective load capacity and shorten bearing life significantly.
