Our bearing load calculator helps you determine the equivalent load acting on a bearing.
A bearing carries both radial load (acting perpendicular to the shaft) and axial load (acting along the shaft). Since both loads act together, they are combined into a single value called the equivalent bearing load.
Do you want to know the formula for bearing load, its terms, and how to calculate it step by step?
Are you curious about how factors like radial and axial loads affect the performance and life of a bearing? Look no further because you’ve come to the right place!
⚙ Bearing Load Calculator
This bearing load calculator helps you determine the equivalent dynamic bearing load by using the standard formula with X and Y factors. You will also find a quick reference table with common bearing values and a worked example to understand the calculation better.
📌 Bearing Load Formula
P = X × Fr + Y × Fa
- P – Equivalent dynamic bearing load
- Fr – Radial load (N)
- Fa – Axial load (N)
- X, Y – Bearing factors (depend on bearing type)
📋 Bearing Load Reference Table
| Bearing Type | X (Dynamic Factor) | Y (Static Factor) |
|---|---|---|
| Deep Groove Ball Bearing | 1.0 | 0.5 |
| Angular Contact Bearing | 0.6 | 1.6 |
| Cylindrical Roller Bearing | 0.67 | 0.33 |
| Spherical Roller Bearing | 0.67 | 0.67 |
🔎 Worked Example
Problem: A deep groove ball bearing is subjected to a radial load of 2000 N and an axial load of 500 N. Calculate the equivalent dynamic bearing load.
Step 1: Identify factors → X = 1.0, Y = 0.5
Step 2: Apply formula → P = (1.0 × 2000) + (0.5 × 500)
Step 3: Calculate → P = 2000 + 250 = 2250 N
FAQs
What is equivalent bearing load?
It is the radial and axial loads placed on a bearing, multiplied by dynamic and static factors.
What are the typical values of X and Y factors?
X and Y also rely on the bearing. For instance, deep groove ball bearings generally have X = 1 and Y = 0.5. Always check the manufacturer’s catalog.
Why are X and Y factors important in bearing calculations?
They modify a radial load and an axial load for bearing type, direction of load, and operating condition in order to find a more realistic equivalent bearing load.
