Dynamic load tests simulate real-world operational conditions where the bearings experience movement under load.
- **Test Procedure:** Bearings are installed in test rigs that replicate actual operating conditions, and various loads are applied to assess performance metrics such as temperature rise and vibration levels.

3. Fatigue Testing

Fatigue testing determines how long a bearing can operate under cyclic loading before failure occurs.
- **Test Procedure:** Bearings are subjected to repeated loading cycles, gradually increasing the load until failure occurs. This helps establish the fatigue life of the bearing.

4. Temperature Performance Testing

Temperature performance testing assesses how the bearings perform at elevated temperatures, which is essential for applications in harsh environments.
- **Test Procedure:** The bearings are operated at specified temperatures while monitoring performance indicators such as lubrication effectiveness and wear rates.
