Detailed Description
Steam Turbine Bearing Bush is a critical support component in steam turbine rotor systems, optimizing low-friction performance and reducing equipment vibration. Made from Babbitt metal or high-strength steel, the surface is treated with precision coating, withstanding temperatures up to 500°C and a tolerance of ±0.02mm. It excels in fatigue resistance and self-lubrication, offering a lifespan exceeding 8 years, ideal for high-pressure power generation maintenance. Applications include global power facility upgrades and retrofits.
