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.
Standards
The system is applicable to testing and evaluation in accordance with the following standards and guidelines:
(1) GB/T 307.1 — Rolling Bearings — Dynamic Performance Test Methods
(2) GB/T 307.2 — Rolling Bearings — Friction and Endurance Test Methods
(3) ISO 15243 — Rolling Bearings — Damage and Failure Terminology
(4) ASTM D7048 — Standard Test Method for Measurement of Bearing Friction and Lubrication Performance
(5) DIN 51819 — Lubrication and Fatigue Testing of Rolling Bearings
(6) ISO 281 — Rolling Bearings — Dynamic Load Ratings and Rating Life
(7) — Measurement of Mechanical Vibration
