Rolling Bearing Tribometer
The Rolling Bearing Tribometer is a laboratory test system used to measure friction losses, temperature rise, and dynamic behavior of rolling element bearings under controlled load and speed conditions. The system is suitable for testing a wide range of rolling bearings, including axial-load and heavy-duty taper roller bearings. Two interchangeable test assemblies allow operation under low-load and high-load conditions, enabling accurate friction and durability evaluation across different bearing sizes and load classes.
